Dude. One of the reasons Project Farm is so good is because he shows his rankings/info for every product he tests for that video. If you don't want to make your spreadsheet available to the public for free for whatever reason, charge a dollar or two for it but damn, make that information available please!
Project Farm is ok, but I wouldn't consider him as a great source for product reviews and choosing the best product. Since he doesn't specialize in any product or category, his knowledge is very limited. His choice of product brands to compare is very small and he doesn't always choose the best ones to compare in that category. He usually just picks some cheap Amazon/Harbor Freight products and compares them to a couple of name brands. He then creates a few tests, picks a couple winners and calls it a day. He then moves on to another product. Project Farm showing his data is pointless because it doesn't have enough data on any specific product category compared to channels like Vacuum Wars and Toolbox Buzz who specialize in specific categories. It would be nice if Vacuum Wars would show us theirs so we can eliminate the categories that aren't important to us., like Toolbox Buzz does, but I'd still hold Vacuum Wars opinions higher than Project Farm. Go see Project Farm's vacuum comparisons. They kind of suck because of the ones he chose to compare and lack of other brands.

The best filter isn’t even listed. It is the filter queen defender. It is a class II medical device because it is so effective and removes particles, including viruses, spores, mold, bacteria, etc. below one micron and below one micron is there requirement for medical devices for the air. It’s a filter that literally can be used in a hospital. And it’s also, 3times more effective than HEPA filters.
I'm not sure anything should win via features. Dyson is known for its gimmick features, things that really don't make the machine work better but give the illusion that it does. As you can see on your test results, the numbers don't lie. The other machine works better for what one buys it for. Bells and whistles don't make a better product. Bottom line, I want to know what machine is going to function the BEST with the least amount of money going into its upkeep. Filters are expensive and that should factor in to your assessment. Sadly I'm disappointed this gave Dyson the win when the only thing it won on was the bells and whistles, not the actual function of the unit. Pretty products don't matter when the pocket book is getting smaller.
@@larsisaksen I disagree, "features" should be "Effectiveness of Filtration", "Speed of Filtration", and "Longevity" But they aren't here. HERE, things like heat, Alexa, AQM (Air Quality Montior ... which is so dumb, you want your monitor on the OTHER SIDE of room as the cleaner, the same way the thermostat on your A/C isn't ATTACHED to your A/C unit.) Which is dumb, and isn't in keeping with the idea that the best air filter should win. FTR, the Dyson is ~1100, the IQAir HPP is ~900.
@djericjames again. These are features that makes the product better for the user. Some people might not need them, but that doesn't make the product worse. A cheaper product, that works as well, but has bonus features, is better.
Great video but it's disappointing you don't show or publish all the raw data of your tests. Would greatly increase the value of these videos. Keep up the good work!
Winix isn't sealed, so once the filter gets used air starts to go around the edges. You need to consider filters that are in a used state, not just new filters.
I've used winix for years and glad they made the list, though admittedly one of their best selling points is that they don't produce ozone with their sanitizer. Something alot of companies can't say.
Feedback: it would be amazing to have more info about the different Air Purifiers that you tested. In particular, for each section (Best Budget, Best Value, and Best Overall) have a winner and the two runner ups. So in total that would be 3 categories times 3 air purifiers = 9 air purifiers options. Additionally, having the whole list of Air Purifiers that you tested would be a nice-to-have :)
Agreed -- I would love to see a list of everything tested, and their scores & sub-scores. Would be great to find the best purifier for my situation based on categories I do/don't care about.
100% - It would be great to see what the other purifiers tested were. Maybe I'm happy to trade off a bit of value for something that looks better, but unfortunately this review doesn't allow me to do that since they only give the winner for each category.
Another reason why runner ups should be included is the simple fact that not every product is available in all countries. If the category you are interested in was won by a product that you can not buy where you live, you are pretty much walking away from this video empty-handed.
I have Dyson since 5 years now, no complain. Use it everyday in bedroom (I'm allergic). Very efficient machine. Recently I got another one from this company for second room.
Honestly I wasn’t expecting the Dyson at all. Dysons new products have trickled into different markets at different times so I wasn’t sure that the Big + Quiet made it to the states yet. But that’s very surprising to see it win so drastically
Agree I saw a university lab test Dyson products against a handful of other air filters when COVID and indoor air quality was at large on peoples minds, and they got better results taking a basic furnace filter and duct-taping it to a box fan. Makes me suspect.
Nice, I have two Levoit Core 300 at home. I bought them without doing much research other than reading a few Amazon reviews, so I guess I lucked out. They work great for forest fire smoke which is common in my area in the summer. I also have a PM2.5 sensor so I can measure how well they're working.
Im in the market for a true hepa air filter with a carbon filter too. Amazon reviews are saying levoit 300 is the best but vacwars is saying winix and dyson with no raw data. Something seems off.
I have a Dyson Big+Quiet Formaldehyde and I absolutely love it! So quiet and very responsive to air quality changes. I also enjoy all the data that it tracks.
@@BladedRocky No, it does not oscillate, but the unit is on wheels, the cone can be adjusted, and the airflow height is adjustable with the remote or in-app.
I have 2 of the Winix 5500-2 for my house, glad they made the list! I wish I had one that projects air sideways though. In large rooms they tend to make a bubble of a clean zone rather than even dust reduction.
I've owned multiple Dyson air purifiers - HP01, HP03, HP04, and HP06. The HP01 died after 3 years. The HP04 makes an insane clicking noise and Dyson told me I had to drive 2 hours to the closest location to get it serviced. I love their vacuums, but I would NEVER buy another air purifier from them. Recently purchased a few Levoit sizes and am pleasantly surprised with them. I prefer them 10:1 over my Dyson already and they are significantly cheaper.
Hi - I'm considering this item for a room (~18' x 18') to help remove the dust being created by cat litter. However, I don't want the unit's operating noise to scare the cat. Based on your experience, do you think it can do a decent job of keeping dust at bay on low setting? Many thanks if you can respond. (I actually would prefer to buy one of the budget winners but don't know if they'll do a good enough job on low setting 🤷)
For a small medium room (carpet) What would you your first and second choice? 1.Blueair 3410 (aud 450 dollars) 2. COWAY AIRMEGA MIGHTY AP-1512HH Air Purifier (aud 323 dollars) 3.COWAY AIRMEGA 250 (aud 380 dollars) 4. Winix Zero+ Pro 5 Stage (aud 365 dollars) I've been doing so much research for days but cannot decide it on my own. Thanks so much :)
Great work! I love the thorough testing! Just a quick thing, is the spreadsheet with all the scores available? Extremely interested in checking performance regarding reduction of formaldehyde and TVOCs from a new-build home. I could live with no Internet of Things and great connectivity of the unit but value filtering performance the most! Would like to see the Dyson hepa big+quiet formaldehyde vs the IQAir GC Multigas! Maaany thanks!!
Honeywells do a great job, price point is good, third party HEPA filters are a big advantage over other purifiers. I only care for HEPA filtration so the honeywells are the way to go for me. Great performance and an American company.
I just purchased a Winix 5500-2 based on this video! I was in need of a purifier that handled odors since my mother likes to cook indoors now, my Blueair Pure 411 was COMPLETELY blind to strong smells that physically hurt my sinuses.
@@msy7804 It works very well for my bedroom! No funky smells linger for more than hour, not even strong cooking oils, dust accumulation in my room is slightly reduced, and it's been easy to use and maintain. The sleep mode is especially nice, you can barely hear it at all and it's automatic. The only thing is I stuck some black tape over an always-on bright light since I sleep in the dark, but other than that it's been great, I don't plan on replacing it any time soon. 😉👍
thank you thank you thank you... Im your advertiser for free, I recommend this channel to all my friends. Every time I want to buy one of this expensive products I come to this channel to make my decision easy, informed and fast.
I just bought three air purifiers. The BlueAir 211 Max, the Winix C545, and the Dyson TP03. The BluAir and the Winix are great. The Dyson (the most expensive list price) was by far the worse. The Dyson on auto never seems to find a reason to increase fan flow. The other two frequently sense the need. I would really be upset if I paid full price for the Dyson as it was only $98 at Costco - reduced from $559. The new Dyson you picked looks like it might be a better device thaan my TP03.
Love the air purifier review, keep it up and the good work! 👌🏻 Side note; I’ve used many different air puffers for various spaces around home and office. I’d like to see you do a review or comparison video of the LG aerotower! I liked the smart features and aesthetics for my living room. I wasn’t expecting it to give me a $450 level of air purification, but I’ve been happy with it and according to my separate IAQ sensor, it works well, It only struggles against things like smoke when compared to others. As for features and smart integrations it blows away my Levoits & Wyze… speaking of Wyze that’s another obscure air purifier. I got it after seeing it on sale, and eventually moved it to the laundry room because it’s absolutely fantastic with odors (at least with the premium filter. I’d love to see a review of all smart air purifiers verse one another! I think a lot of people these days want smart integrations and see it as a crucial feature. Thanks for the good work!
Since the Winix 5500-2 is the Best Value winner of 2023 compared with other brands, my question is, will you make a comparison between the 4 other Winix models that are shown on Amazon? Seems like there might be better models, for not that much more money.
Would love to see the top of the line Govee air purifier (Govee H7122) tested as well. Offers great integration into smart home systems but would be curious to see how it stacks up from an actual performance perspective.
What is the CDAR of the Dyson BP04 and how does it compare to the Coway Airmega ? The Dyson is advertised to cover 33 feet but what is the CDAR ? The Clean Air Delivery Rate??
I found your channel when I bought my first house 2 years ago and ended up with a vacuum I love. Now I’m back for an air filter and I’m thrilled you have such a detailed breakdown. Great stuff
Amazing research! What air purifier comes to mind if you're looking for one that also works well as a white noise machine for sleep. So a purifier that has a nice consistent deep sound to it and you can manually change the fan speed.
Having one of those things all the time running while sleeping will damage your eardrums in the long term.. believe me, a not so loud sound for years can be much worse than a big bang once..
Would love to see 1) how well they clean up the air 2) cost of filters for these air purifiers: Coway AP-1512HH Mighty Medify MA-112 Nuwave oxypure Shark purifiers HP302 vs HC502 Winix 5500-2 Kenmore PM1005 LEVOIT Core 300
Can you add “Wellis Air” next year? 😍 I’d love to see how they stack up. They’re different in that it’s supposed sanitize not just the air but surfaces too!
So excited! I have the original molekule. I have tried to stay up to date on the ones that filter pathogens out of the air as well as allergens without emitting ozone or other harmful emissions because that would defeat the point
Since these devices are meant to run 24/7 365 days I assume most people, like myself, will be running them on the low setting if an Auto function is not available. I think it would be a great addition to your testing to see how quickly/effectively these devices can clean the air in a room at their lowest settings. I have a hunch a device that performs amazing at high fan speeds might perform terribly at low fan speeds.
Is the raw data available so we can see how all the models performed? This video is unlike the vacuums where we are unable to broaden our selections. Thanks for the work!
I'm sorry but based on which data do you assume the video goes in depth? It looks like an ad to me. If there is no available data, there is no way to be sure.
I found them on Amazon, but if you buy directly from Dyson's site, I'll bet they will upsell you a regular filter replacement subscription with your purchase... ;-)
Any idea if purifier would help with dust in 45m sq flat ? Would love to get rid of dust but dont want constant noise. maybe I could run it while I am at work ?
Since we don't test for dust collection, it would be wrong for us to say either way. Running it while you are away though sounds like a good idea. You can even check the filter when you return to see how it did!
I'm all for this. Personally, I have no need to have features like cord length, data history, alexa compatible, etc affecting the overall score I'm looking for.
Is there such a thing as a motion sensor activated purifier? For example, it's on a low setting but when motion is detected it turns up to high for a few minutes before returning to low.
The Winix on its auto setting, detects no light and light. When it switches to night mode, it goes to a fan speed setting below low. When lights are on, it'll return to normal. Other than that, I haven't seen anything else.
Great video, thanks for such a complete test. I am curious if you have ever put the Vollara Air & Surface Pro+ through these tests? I keep hearing about them and wonder how they stack up to your testing
Really wish you guys would have tested the Molekile Air Pro, since they don't even make the old one you tested way back in the day. Always grateful otherwise, but seriously please add them to your test group. They have sensors and all sorts of new stuff for larger rooms now. Thanks!
Theres nothing to test on air purifiers really. Its all about filter quality and air going in and out. Sensors and lights are just a gimmick to bump up prices. Having a motherboard for air purifiers is so useless lol.
Agreed, it's about one crucial thing beyond the filter; airflow (CFM) -- something their original (non-pro) unit was terrible with apparently. Hence why I'd like to see more data on the large (Pro) unit. Some people don't want high/max airflow all the time (excess noise, power consumption, etc) so a design that can react to existing conditions (cooking particles/smells or VOCs from cleaning products, etc.) is also a big benefit in my opinion/experience. Thanks for the reply! @@JoHn-if6wy
Can you look into the reported bad odors that come on Blueair 411 auto replacement filters? There's a lot of reviews for the replacement filters complaining about a bad smell. And unfortunately I encountered the issue too. I bought a Blueair 411 auto and enjoyed it for 6 months. But when it came time to replace the filter, I had major issues with bad odors on the replacement units. I bought 3 replacements, one of which was directly from Blueair's website. All had a bad odor. The odor is faint. I tried to ignore it (I usually go noseblind easily) but the more time I spent in the room, the more it bothered me. After spending a night with it, my nose and throat were really irritated! Blueair promises the odor will go away after you run the filter for a few days, but it never worked for me. Even running it outdoors for 2 days. After 6 months of use, I have to throw it away and try to shop for a new system that doesn't use Blueair's filters. Is it possible that there is bad stock at my local distribution center? Maybe excessive heat in storage broke down the glue at some point?
Hi there! am about to order an air purifier. Before I do I would really appreciate your advice. After watching this video (and reading lots of reviews) I was about to order the Levoit. BUT then noticed, your most recommended is a Kenmore (budget, and similar in price to the Levoit). Which one would you get if you were going to buy one? I like that the Levoit light can be turned off (in bedroom). It'd be to know the priced of the replacement filters to compare. (Levoit 100s has a washable carbon filter I think. So, maintenance economy is a consideration. Thank you so much for this work!
My man! I've been shopping around for the Better part of a year for air purifiers. I really needed this. I shouldn't only listen to one person but I bought the robot vac, and stick vac I did because of your channel. Edit: now that I have actually watched it, still good, but do you have one broken down by room sizes?
So glad we've helped you out! We don't have them broken down by room size, but we usually mention their room spec really early in the videos. Sorry about that.
Why wasn't the Enviroklenz air purifier added to your testing, if you had a great impression of it in a previous video? Does the fact you left it out imply it doesn't stack up to the Dyson or IQ Air?
Are the circular, 360 filters better than the flat filters? Right not I have a Dayette AP304 (1 rectangular filter on both sides) but was considering getting a Air Purifier that has a circular 360 filter. Anyone care to chime in? they are similar price for filters.
I'd like to see how popular portable purifiers do. The Pure Enrichment PureZone mini is very popular among cc folks and I can't keep from thinking that it's just a glorified fan and it doesn't actually do much. Some people lug around purifiers like the smaller levoits but they aren't easily portable.
2:36 you know your video and your website give different answers to which one is the best budget purifier. this video says it's the Kenmore PM1005. However, your website says it's the Levoit Core 300. Confusing.
I'm really sad that the darlings of the wellness community we're not included in this lineup. At least not that I could see because you guys didn't give us a full rundown of all the models reviewed. I even checked the website and couldn't find the complete list. But I'd really like to see the air doctor, the Mila, and maybe you guys already did the molekule, but that one maybe isn't even worth it at this point because it's been discredited so heavily. Seriously though, would love a longer more in-depth video on this subject. Would love to know more about all the different models evaluated. And would really really really love to see the Air Doctor and the Mila included. I'm less interested in the ones I'm likely to run into in the store and more interested in the ones that are so heavily advertised and marketed especially through influencers.
They did test the Molekule, a few months after I bought three of them. The Molekule came in dead last in a test of several (five?) air filters/purifiers that claimed to kill viruses. Made me very sad. I'm finally buying a couple of new air filters/purifiers, a Winix and a Kenmore (from this video review). I hope they will help keep our home's air clean while it's mostly sealed up during the long winter. (it is a very well-sealed house, near zero drafts, which can be a gift or a curse, depending on the situation.... getting a dehumidifier too)
@@Wordsmiths After a few years of tackling air filtration and monitoring in our home, which is a mid-sized apartment in the Northeast US, I've learned some lessons. 1) The biggest problem isn't filtration, it's ventilation. No filter that exists can "filter" CO2 and other gases (they aren't particles) and the only answer is getting fresh air from the outside. If you've got forced-air heat like we do, then that helps and you can run the fan to help circulate air to prevent CO2 building (eg in bedrooms at night if you tend to shut the doors). But, you're screwed if you've got radiant heat or a mini-split heat pump. And you're REALLY screwed if you have a gas stove/oven. We need to open our front and back windows to use our oven without our CO2 levels skyrocketing to concerning levels (and staying there for hours and hours even after we're done). 2) VOC filtration seems like a scam and no one seems to really know what they're talking about. None of the 3 units I personally tested made a difference. If my wife paints her nails or uses a burns a candle or if we cook inside, we have to open the windows to get the VOC level down. This may partially be due to VOC detectors being super ambiguous in what they are detecting. You might think that "Total VOC" readings from a lab-certified meter or home product designed to test for VOCs would mean "all" of the various volatile organic compounds in the air. Nope. It's just all of the specific VOCs that meter is designed to detect. Which they don't always advertise or document, and none that I've found actually gives the user a way to see the levels of each class/specific one. So, every time we pour some wine or have a few beers, those alcohol vapors are enough to set off one of our air quality monitors for VOC, while the other one stays silent. 3) Cooking inside = you need ventilation. Even if you have an electric or induction cooker, you're going to produce VOCs and particulates that your filter is going to have to turn all the way up to high for a while before it makes a difference. That's gonna be loud and stay loud for a while. And, of course, lots of those VOCs aren't going to be removed by that carbon filter no matter what the manufacturer says. You either need a REAL kitchen ventilation system with a strong (commercial grade) fan and an actual external exhaust, or open all your windows. That little fan built into the bottom of your cabinet probably does nothing if it isn't built into a ventilation shaft that goes to an outside wall. 4) Humidity matters. For those of us in the cold climates, life sucks when it comes to humidity in winter. And ventilation only makes that WORSE. You need a humidifier. And those "cool mist" ones that produce visible vapor are actually vaporizers, which is only going to put more particles into the air unless you're using distilled water. They can also OVER-humidify even when they have controls that set a specific humidity, because nearby items can end up with condensation from the mist. An evaporative humidifier is the way to go. It won't put particles into the air and the drier your air the faster the evaporation will happen yet it will naturally slow as the air becomes more saturated. Physics. In any case, it's not as fast acting and it will take time to normalize humidity in winter after you've had to open the windows to flush the air because you cooked dinner. Which leads me to the last lesson. 5) There's no comprehensive solution for managing home air quality. We're fighting problems with no practical solution (how to get ventilation if you don't have HVAC) and some problems have opposite answers so you solve one problem just to cause another. Maybe in the future homes will have HVAC systems that also manage humidity levels, temp, CO2, gases, VOCs, and PM filtration all on a room-by-room basis. But right now... good luck with that. Living in an apartment that doesn't even have zone based heating, we have to put boards over some vents downstairs just to get enough heat to the bedrooms upstairs without roasting the downstairs in the process. So we have to cover/uncover vents, turn the fan on/off, open windows, run a humidifier, and still run multiple HEPA filters just to try and manage, however imperfectly, the indoor air. And that's just the stuff we have tools to measure. I'm sure there's other stuff. Currently, the most comprehensive air quality monitor I've found is the Uhoo. It monitors Temp, humidity, PM2.5, CO2, CO, Ozone, NO2, air pressure, and of course "VOCs" (if those are high, good luck trying to figure out if it's from sewer gases, off-gassing furniture, or just your dog having flatulence). Sadly, it doesn't measure PM1, PM10, either, unless you get the Business model. The consumer model is already very expensive and buying one per room or even one per floor is a lot. There are some cheaper options but none that get the right mix of sensors for my preference (the amazon ones for Echo don't even do CO2, which is weird). Good luck to anyone reading this. But once you go down the rabbit hole... you'll miss the days when you would just breath air mindlessly, no matter if someone had just burned the crap out of a telfon pain in the kitchen.
Have you tested any of the large Bissell air purifiers? I ended up going with the air400 a few months back despite them not getting much attention because the filters seemed very high quality (carbon pellet honeycomb instead of carbon infused pad), replacement filters were far cheaper than the Shark I was also considering, it was well priced compared to others with similar specs, and was from a brand I know and trust. I don't have a very scientific way to test them, so I'm curious how they actually perform compared to others.

It'd be useful so people could apply their own algorithm for what's important to them.
Any luck finding the spreadsheet?
I've used winix for years and glad they made the list, though admittedly one of their best selling points is that they don't produce ozone with their sanitizer. Something alot of companies can't say.
Thanks for the tip, that confirms my decision to buy @ least one.
Feedback: it would be amazing to have more info about the different Air Purifiers that you tested. In particular, for each section (Best Budget, Best Value, and Best Overall) have a winner and the two runner ups. So in total that would be 3 categories times 3 air purifiers = 9 air purifiers options. Additionally, having the whole list of Air Purifiers that you tested would be a nice-to-have :)
Agreed -- I would love to see a list of everything tested, and their scores & sub-scores.
Would be great to find the best purifier for my situation based on categories I do/don't care about.
poor review. where are the other purifiers' individual scores? he didn't even post on their website. are we supposed to pick wherever you say?
100% - It would be great to see what the other purifiers tested were. Maybe I'm happy to trade off a bit of value for something that looks better, but unfortunately this review doesn't allow me to do that since they only give the winner for each category.
Another reason why runner ups should be included is the simple fact that not every product is available in all countries. If the category you are interested in was won by a product that you can not buy where you live, you are pretty much walking away from this video empty-handed.
Really hope my big+quiet shows up well! It made a huge difference on the freshness of air on the main floor of my townhouse which lacks a ceiling fan.
oh my yeah I didn't even see it at first
Ooh is it actually that quirt
I have Dyson since 5 years now, no complain. Use it everyday in bedroom (I'm allergic). Very efficient machine. Recently I got another one from this company for second room.
I LOVE UR CHANNEL! u do so much of my favourite things and even have my 2nd fav robot vacuum! the LG Hom Bot Square!😀😃😄😁🙂🙃😊😇🥰😍🤩☺
Roomba 02!
@@mileslife366thanks! 😁
Honestly I wasn’t expecting the Dyson at all. Dysons new products have trickled into different markets at different times so I wasn’t sure that the Big + Quiet made it to the states yet. But that’s very surprising to see it win so drastically
Agree I saw a university lab test Dyson products against a handful of other air filters when COVID and indoor air quality was at large on peoples minds, and they got better results taking a basic furnace filter and duct-taping it to a box fan. Makes me suspect.
@@rickmurillo6857your intuitions are probably correct
Note that it won on features, not in air purification specifically. 4:37 shows IQ Air doing ~25% better in particle reduction.
Nice, I have two Levoit Core 300 at home. I bought them without doing much research other than reading a few Amazon reviews, so I guess I lucked out. They work great for forest fire smoke which is common in my area in the summer. I also have a PM2.5 sensor so I can measure how well they're working.
That is good to hear. Glad you are happy with it.
I had to return mine bc it was giving off a bad chemical smell
Im in the market for a true hepa air filter with a carbon filter too. Amazon reviews are saying levoit 300 is the best but vacwars is saying winix and dyson with no raw data. Something seems off.
@@msy7804I don't think the Core 300 is the best overall, just good for its price and size.
Thank you for this video. Only one thing: quieter is not always better for some people. I actually like the steady sound of a fan. Helps me sleep.
I am obsessed with air quality. Love this!!!!
I own a Lupe, a Shark and now I'm buying a Dyson big + quiet. Vacuum wars is my fav youtube channel.
We hope you enjoy them all!
I have a Dyson Big+Quiet Formaldehyde and I absolutely love it! So quiet and very responsive to air quality changes. I also enjoy all the data that it tracks.
Is It oscilating too?
@@BladedRocky No, it does not oscillate, but the unit is on wheels, the cone can be adjusted, and the airflow height is adjustable with the remote or in-app.
How does the Dyson do concerning odor????
Yeah and IT also has pathetic Mass of charcoal
Is there another one like this that’s less expensive ? 🙏
I know more about air purifiers and vacuums than any of my friends and this channel is the reason why.
😃
I have 2 of the Winix 5500-2 for my house, glad they made the list! I wish I had one that projects air sideways though. In large rooms they tend to make a bubble of a clean zone rather than even dust reduction.
I have 10 throughout my 2500sq ft house 😆 bought them all off of warehouse deals for like $110 each
I've owned multiple Dyson air purifiers - HP01, HP03, HP04, and HP06. The HP01 died after 3 years. The HP04 makes an insane clicking noise and Dyson told me I had to drive 2 hours to the closest location to get it serviced. I love their vacuums, but I would NEVER buy another air purifier from them. Recently purchased a few Levoit sizes and am pleasantly surprised with them. I prefer them 10:1 over my Dyson already and they are significantly cheaper.
I havethe Winix one for a few months now, Its very good. Best performance/price ratio
Hi - I'm considering this item for a room (~18' x 18') to help remove the dust being created by cat litter. However, I don't want the unit's operating noise to scare the cat. Based on your experience, do you think it can do a decent job of keeping dust at bay on low setting? Many thanks if you can respond. (I actually would prefer to buy one of the budget winners but don't know if they'll do a good enough job on low setting 🤷)
@@gibbersking6575 i dont have pets so i cant say how it will affect your cats. But its very quiet, i sleep/work while its on.
the information value to video length ratio on this is insane. thanks for making this video.
Glad you enjoyed it! thank you!
For a small medium room (carpet) What would you your first and second choice?
1.Blueair 3410 (aud 450 dollars)
2. COWAY AIRMEGA MIGHTY AP-1512HH Air Purifier (aud 323 dollars)
3.COWAY AIRMEGA 250 (aud 380 dollars)
4. Winix Zero+ Pro 5 Stage (aud 365 dollars)
I've been doing so much research for days but cannot decide it on my own.
Thanks so much :)
Great work! I love the thorough testing! Just a quick thing, is the spreadsheet with all the scores available? Extremely interested in checking performance regarding reduction of formaldehyde and TVOCs from a new-build home. I could live with no Internet of Things and great connectivity of the unit but value filtering performance the most! Would like to see the Dyson hepa big+quiet formaldehyde vs the IQAir GC Multigas! Maaany thanks!!
Any luck finding the spreadsheet?
i wish that your videos would get so much more veiws showing how much effort you put into them.
Thank you!
Winix in every room and rehearsals.
Honeywells do a great job, price point is good, third party HEPA filters are a big advantage over other purifiers. I only care for HEPA filtration so the honeywells are the way to go for me. Great performance and an American company.
I just purchased a Winix 5500-2 based on this video! I was in need of a purifier that handled odors since my mother likes to cook indoors now, my Blueair Pure 411 was COMPLETELY blind to strong smells that physically hurt my sinuses.
Hope you enjoy it!
Any update? Will it rid the smell of fried garlic
@@msy7804 It works very well for my bedroom! No funky smells linger for more than hour, not even strong cooking oils, dust accumulation in my room is slightly reduced, and it's been easy to use and maintain. The sleep mode is especially nice, you can barely hear it at all and it's automatic. The only thing is I stuck some black tape over an always-on bright light since I sleep in the dark, but other than that it's been great, I don't plan on replacing it any time soon. 😉👍
thank you thank you thank you... Im your advertiser for free, I recommend this channel to all my friends. Every time I want to buy one of this expensive products I come to this channel to make my decision easy, informed and fast.
Thank you too!
3:23 what are your 3rd, 4th, 5th, 6th, and 7th places?
I just bought three air purifiers. The BlueAir 211 Max, the Winix C545, and the Dyson TP03. The BluAir and the Winix are great. The Dyson (the most expensive list price) was by far the worse. The Dyson on auto never seems to find a reason to increase fan flow. The other two frequently sense the need.
I would really be upset if I paid full price for the Dyson as it was only $98 at Costco - reduced from $559.
The new Dyson you picked looks like it might be a better device thaan my TP03.
hi any thoughts on Blueair 7770i vs 211i max ? i m not able to decide....
I can't believe how high quality this review is genuinely thank you
Love the air purifier review, keep it up and the good work! 👌🏻
Side note; I’ve used many different air puffers for various spaces around home and office. I’d like to see you do a review or comparison video of the LG aerotower! I liked the smart features and aesthetics for my living room. I wasn’t expecting it to give me a $450 level of air purification, but I’ve been happy with it and according to my separate IAQ sensor, it works well, It only struggles against things like smoke when compared to others. As for features and smart integrations it blows away my Levoits & Wyze… speaking of Wyze that’s another obscure air purifier. I got it after seeing it on sale, and eventually moved it to the laundry room because it’s absolutely fantastic with odors (at least with the premium filter.
I’d love to see a review of all smart air purifiers verse one another! I think a lot of people these days want smart integrations and see it as a crucial feature.
Thanks for the good work!
Cool input! Thank you!
Since the Winix 5500-2 is the Best Value winner of 2023 compared with other brands, my question is, will you make a comparison between the 4 other Winix models that are shown on Amazon? Seems like there might be better models, for not that much more money.
Would love to see the top of the line Govee air purifier (Govee H7122) tested as well. Offers great integration into smart home systems but would be curious to see how it stacks up from an actual performance perspective.
This is the content I need as we approach allergy season. 💪🏽🤠🇺🇸
What is the CDAR of the Dyson BP04 and how does it compare to the Coway Airmega ? The Dyson is advertised to cover 33 feet but what is the CDAR ? The Clean Air Delivery Rate??
Thank you ! I dont make air purifier let alone vacuum purchasing decisions without consulting this channel
the intro to all the categories taken into account was just pure perfection and had me hooked. thank you!
I found your channel when I bought my first house 2 years ago and ended up with a vacuum I love.
Now I’m back for an air filter and I’m thrilled you have such a detailed breakdown. Great stuff
That is awesome! Thank you for coming back!
seems he fell for the Dyson hype. I have the Levoit Core 300 and it does everything I need while saving $1000
Amazing research! What air purifier comes to mind if you're looking for one that also works well as a white noise machine for sleep. So a purifier that has a nice consistent deep sound to it and you can manually change the fan speed.
Having one of those things all the time running while sleeping will damage your eardrums in the long term.. believe me, a not so loud sound for years can be much worse than a big bang once..
😂
@@Trikipumthat could be old age catching up. Lol I’ve had white noise while sleeping for the past 20 years. I can hear the same. Idk maybe I’m lucky.
Would love to see 1) how well they clean up the air 2) cost of filters for these air purifiers:
Coway AP-1512HH Mighty
Medify MA-112
Nuwave oxypure
Shark purifiers HP302 vs HC502
Winix 5500-2
Kenmore PM1005
LEVOIT Core 300
I use the winix. Works well.
Great to hear that! Thanks for commenting!
Hello. How did you manage to insert the big purifiers in your fridge?
Awesome benchmark! Do you mind sharing that Sheet with us? I couldn’t find the link.
I just have seen what you are about to do and I love it! Thank you for your work, will def buy via your link!!
Thank you!
Can you add “Wellis Air” next year? 😍 I’d love to see how they stack up. They’re different in that it’s supposed sanitize not just the air but surfaces too!
So excited! I have the original molekule. I have tried to stay up to date on the ones that filter pathogens out of the air as well as allergens without emitting ozone or other harmful emissions because that would defeat the point
Molekule is basically a scam
What is molekule??
Since these devices are meant to run 24/7 365 days I assume most people, like myself, will be running them on the low setting if an Auto function is not available. I think it would be a great addition to your testing to see how quickly/effectively these devices can clean the air in a room at their lowest settings. I have a hunch a device that performs amazing at high fan speeds might perform terribly at low fan speeds.
Is the raw data available so we can see how all the models performed? This video is unlike the vacuums where we are unable to broaden our selections. Thanks for the work!
We aren't able to release the spreadsheet, but we hope the video still is helpful. Thank you!
Because your paid by sponsors😢
Does the LevoitCore 300, perform the same as Xiaomi Air Purifier? They both look almost identical on the outside.
Can you recommend an air purifier with permanent HEPA filters that do not need to nr replaced?
Were the Austin Air purifiers tested? I didn't see them pictured, but would be curious about how they compare
There is no channel that goes this in depth. Thank you. Bought the shark apex vacuum because of you
Thank you and we hope you enjoy that Shark!
You never heard of project farm?
I'm sorry but based on which data do you assume the video goes in depth? It looks like an ad to me. If there is no available data, there is no way to be sure.
@@goku445 check his vacuum videos
Thank you for the video, is there any chance we can have a look at the spreadsheet? Thank you!
Imagine running all 30 of those air purifiers at once
Hi! I like the Dyson, you mention the filters are cheaper, where are their filters on their website?
I found them on Amazon, but if you buy directly from Dyson's site, I'll bet they will upsell you a regular filter replacement subscription with your purchase... ;-)
The levoit is one i bought based on your review a while back - used it several months and like a lot! Thanks!!!
Thank you so much for all your research and work this was very helpful!
Glad it was helpful!
surprised to see that crazy dyson win the best overall! 😳
I am looking for one that will collect the most dust in my gaming room. Any recommendations would be apricated. Thank you
wow, this is one legit review video. Awesome work!
Wow, thanks!
What are the air quality testers used?
Which one is the best for dust reduction on a single room? I dont care about how big it is, just dust removal on the air
Obviously paid by Dyson
Any idea if purifier would help with dust in 45m sq flat ? Would love to get rid of dust but dont want constant noise. maybe I could run it while I am at work ?
Since we don't test for dust collection, it would be wrong for us to say either way. Running it while you are away though sounds like a good idea. You can even check the filter when you return to see how it did!
Does the BP04 work the same as the BP03? Especially for filtering out smoke?
Would you suggest the dyson p07?
Thank you guys for your ratings! Super helpful, with trying to figure out what to buy
Is there anywhere to see the score chart online?
I'm all for this. Personally, I have no need to have features like cord length, data history, alexa compatible, etc affecting the overall score I'm looking for.
Two minutes in and I love this video. Thank you so much!
You are so welcome!
@VacuumWars. Great review. Where do I find the master spreadsheet with all the data?
Thank you! but sorry - we aren't able to share that. We hope the video is helpful.
Dayum, this is right up there with Project Farm efficiency! I hope you get the million views per video that he gets!
Great video… what I want to know is… will a good air purifier improve the quality if my life? Is it really that useful?
Is there such a thing as a motion sensor activated purifier? For example, it's on a low setting but when motion is detected it turns up to high for a few minutes before returning to low.
We have not seen that, but it is a cool idea!
The Winix on its auto setting, detects no light and light. When it switches to night mode, it goes to a fan speed setting below low. When lights are on, it'll return to normal.
Other than that, I haven't seen anything else.
Great video, thanks for such a complete test. I am curious if you have ever put the Vollara Air & Surface Pro+ through these tests? I keep hearing about them and wonder how they stack up to your testing
Really wish you guys would have tested the Molekile Air Pro, since they don't even make the old one you tested way back in the day.
Always grateful otherwise, but seriously please add them to your test group. They have sensors and all sorts of new stuff for larger rooms now.
Thanks!
Theres nothing to test on air purifiers really. Its all about filter quality and air going in and out.
Sensors and lights are just a gimmick to bump up prices. Having a motherboard for air purifiers is so useless lol.
Agreed, it's about one crucial thing beyond the filter; airflow (CFM) -- something their original (non-pro) unit was terrible with apparently. Hence why I'd like to see more data on the large (Pro) unit. Some people don't want high/max airflow all the time (excess noise, power consumption, etc) so a design that can react to existing conditions (cooking particles/smells or VOCs from cleaning products, etc.) is also a big benefit in my opinion/experience. Thanks for the reply! @@JoHn-if6wy
Can you look into the reported bad odors that come on Blueair 411 auto replacement filters?
There's a lot of reviews for the replacement filters complaining about a bad smell. And unfortunately I encountered the issue too.
I bought a Blueair 411 auto and enjoyed it for 6 months. But when it came time to replace the filter, I had major issues with bad odors on the replacement units.
I bought 3 replacements, one of which was directly from Blueair's website. All had a bad odor.
The odor is faint. I tried to ignore it (I usually go noseblind easily) but the more time I spent in the room, the more it bothered me. After spending a night with it, my nose and throat were really irritated!
Blueair promises the odor will go away after you run the filter for a few days, but it never worked for me. Even running it outdoors for 2 days.
After 6 months of use, I have to throw it away and try to shop for a new system that doesn't use Blueair's filters.
Is it possible that there is bad stock at my local distribution center? Maybe excessive heat in storage broke down the glue at some point?
Hi there! am about to order an air purifier. Before I do I would really appreciate your advice. After watching this video (and reading lots of reviews) I was about to order the Levoit. BUT then noticed, your most recommended is a Kenmore (budget, and similar in price to the Levoit). Which one would you get if you were going to buy one? I like that the Levoit light can be turned off (in bedroom). It'd be to know the priced of the replacement filters to compare. (Levoit 100s has a washable carbon filter I think. So, maintenance economy is a consideration. Thank you so much for this work!
What's the difference between the Shark HC501and the Shark HP502? Also, will the Shark HC501 heat a fully insulated, 300 square foot he/she/kids shed?
Instant like for the extensive testing criteria.
Looking for a countertop air filter for kitchen range top fumes.
Replacement filter is where they get you.
My man! I've been shopping around for the Better part of a year for air purifiers. I really needed this. I shouldn't only listen to one person but I bought the robot vac, and stick vac I did because of your channel.
Edit: now that I have actually watched it, still good, but do you have one broken down by room sizes?
So glad we've helped you out! We don't have them broken down by room size, but we usually mention their room spec really early in the videos. Sorry about that.
Wow, thorough review. Awesome
Much appreciated!
Bless you for these videos :)))) very little quality no fluff these days
We try! Thank you!
Where can I see the ranking? Would be nice to know the second and third best on each category. ?
Why wasn't the Enviroklenz air purifier added to your testing, if you had a great impression of it in a previous video? Does the fact you left it out imply it doesn't stack up to the Dyson or IQ Air?
What about the Sensibo Pure? Is it any good?
Are the circular, 360 filters better than the flat filters? Right not I have a Dayette AP304 (1 rectangular filter on both sides) but was considering getting a Air Purifier that has a circular 360 filter. Anyone care to chime in? they are similar price for filters.
guys whats the best for sulphur dioxide and nox? I live close to a cement factory... thank you
I'd like to see how popular portable purifiers do. The Pure Enrichment PureZone mini is very popular among cc folks and I can't keep from thinking that it's just a glorified fan and it doesn't actually do much. Some people lug around purifiers like the smaller levoits but they aren't easily portable.
I would love to see a dehumidifier video. I can't fine a person that does good reviews on them like this.
Any tests done on Daikin models? Curious about their stream tech and their filters last 10 years.
2:36 you know your video and your website give different answers to which one is the best budget purifier. this video says it's the Kenmore PM1005. However, your website says it's the Levoit Core 300. Confusing.
Is there somewhere that you provide a list of the purifiers that you tested? Wondering where the Ibuki L falls in the rankings.
I'm really sad that the darlings of the wellness community we're not included in this lineup. At least not that I could see because you guys didn't give us a full rundown of all the models reviewed. I even checked the website and couldn't find the complete list. But I'd really like to see the air doctor, the Mila, and maybe you guys already did the molekule, but that one maybe isn't even worth it at this point because it's been discredited so heavily.
Seriously though, would love a longer more in-depth video on this subject. Would love to know more about all the different models evaluated. And would really really really love to see the Air Doctor and the Mila included. I'm less interested in the ones I'm likely to run into in the store and more interested in the ones that are so heavily advertised and marketed especially through influencers.
Yeah this seemed like an AI summary.
They did test the Molekule, a few months after I bought three of them. The Molekule came in dead last in a test of several (five?) air filters/purifiers that claimed to kill viruses. Made me very sad. I'm finally buying a couple of new air filters/purifiers, a Winix and a Kenmore (from this video review). I hope they will help keep our home's air clean while it's mostly sealed up during the long winter. (it is a very well-sealed house, near zero drafts, which can be a gift or a curse, depending on the situation.... getting a dehumidifier too)
@@Wordsmiths After a few years of tackling air filtration and monitoring in our home, which is a mid-sized apartment in the Northeast US, I've learned some lessons.
1) The biggest problem isn't filtration, it's ventilation. No filter that exists can "filter" CO2 and other gases (they aren't particles) and the only answer is getting fresh air from the outside. If you've got forced-air heat like we do, then that helps and you can run the fan to help circulate air to prevent CO2 building (eg in bedrooms at night if you tend to shut the doors). But, you're screwed if you've got radiant heat or a mini-split heat pump. And you're REALLY screwed if you have a gas stove/oven. We need to open our front and back windows to use our oven without our CO2 levels skyrocketing to concerning levels (and staying there for hours and hours even after we're done).
2) VOC filtration seems like a scam and no one seems to really know what they're talking about. None of the 3 units I personally tested made a difference. If my wife paints her nails or uses a burns a candle or if we cook inside, we have to open the windows to get the VOC level down. This may partially be due to VOC detectors being super ambiguous in what they are detecting. You might think that "Total VOC" readings from a lab-certified meter or home product designed to test for VOCs would mean "all" of the various volatile organic compounds in the air. Nope. It's just all of the specific VOCs that meter is designed to detect. Which they don't always advertise or document, and none that I've found actually gives the user a way to see the levels of each class/specific one. So, every time we pour some wine or have a few beers, those alcohol vapors are enough to set off one of our air quality monitors for VOC, while the other one stays silent.
3) Cooking inside = you need ventilation. Even if you have an electric or induction cooker, you're going to produce VOCs and particulates that your filter is going to have to turn all the way up to high for a while before it makes a difference. That's gonna be loud and stay loud for a while. And, of course, lots of those VOCs aren't going to be removed by that carbon filter no matter what the manufacturer says. You either need a REAL kitchen ventilation system with a strong (commercial grade) fan and an actual external exhaust, or open all your windows. That little fan built into the bottom of your cabinet probably does nothing if it isn't built into a ventilation shaft that goes to an outside wall.
4) Humidity matters. For those of us in the cold climates, life sucks when it comes to humidity in winter. And ventilation only makes that WORSE. You need a humidifier. And those "cool mist" ones that produce visible vapor are actually vaporizers, which is only going to put more particles into the air unless you're using distilled water. They can also OVER-humidify even when they have controls that set a specific humidity, because nearby items can end up with condensation from the mist. An evaporative humidifier is the way to go. It won't put particles into the air and the drier your air the faster the evaporation will happen yet it will naturally slow as the air becomes more saturated. Physics. In any case, it's not as fast acting and it will take time to normalize humidity in winter after you've had to open the windows to flush the air because you cooked dinner. Which leads me to the last lesson.
5) There's no comprehensive solution for managing home air quality. We're fighting problems with no practical solution (how to get ventilation if you don't have HVAC) and some problems have opposite answers so you solve one problem just to cause another. Maybe in the future homes will have HVAC systems that also manage humidity levels, temp, CO2, gases, VOCs, and PM filtration all on a room-by-room basis. But right now... good luck with that. Living in an apartment that doesn't even have zone based heating, we have to put boards over some vents downstairs just to get enough heat to the bedrooms upstairs without roasting the downstairs in the process. So we have to cover/uncover vents, turn the fan on/off, open windows, run a humidifier, and still run multiple HEPA filters just to try and manage, however imperfectly, the indoor air. And that's just the stuff we have tools to measure. I'm sure there's other stuff.
Currently, the most comprehensive air quality monitor I've found is the Uhoo. It monitors Temp, humidity, PM2.5, CO2, CO, Ozone, NO2, air pressure, and of course "VOCs" (if those are high, good luck trying to figure out if it's from sewer gases, off-gassing furniture, or just your dog having flatulence). Sadly, it doesn't measure PM1, PM10, either, unless you get the Business model. The consumer model is already very expensive and buying one per room or even one per floor is a lot. There are some cheaper options but none that get the right mix of sensors for my preference (the amazon ones for Echo don't even do CO2, which is weird).
Good luck to anyone reading this. But once you go down the rabbit hole... you'll miss the days when you would just breath air mindlessly, no matter if someone had just burned the crap out of a telfon pain in the kitchen.
Curious why the Winix was placed at Best Value when in your Air Purifier Wars series the Coway actually beat out the Winix?
Have you tested any of the large Bissell air purifiers? I ended up going with the air400 a few months back despite them not getting much attention because the filters seemed very high quality (carbon pellet honeycomb instead of carbon infused pad), replacement filters were far cheaper than the Shark I was also considering, it was well priced compared to others with similar specs, and was from a brand I know and trust. I don't have a very scientific way to test them, so I'm curious how they actually perform compared to others.
Not yet, but we hope to.
