I’m very pleased with mine - it does exactly what it’s supposed to. I did all of my “research” within the first couple of days. The only real surprise for me was the buildup in the car; I’m not using “recirculate” anymore! It was fun the first couple of days blaming any spike in the CO2 levels on the wife’s incessant talking ! - but it didn’t take her long to realize that simply breathing causes the same thing …
I have multiple and I wish there was a software update to allow you to add an offset to the humidity readings as I have one that is consistently 5% high.
Funny you say that -- they actually just dispatched one to our studio -- we should have it soon and will be testing it! Stay tuned, video will be coming too.
I just bought one of these and at first felt a little ripped off with how cheap it felt out of the box considering the high price. After setting it up and using it though, it's simple and works flawlessly at everything it's supposed to do. I also like how they just sell you a good product + app that works without the BS of trying to get you to subscribe to something, pay to unlock features, or constantly displaying ads trying to sell you more of their crap.
@@jacobpetersen5662 The weight and E ink display threw me off at first. It has been 9 months since I posted this comment and it has been working perfectly with half of the original battery still left. Worth every penny.
Idk, I tried the Aranet4 a few weeks ago and compared it with Airthings View Plus, and the Airthings was higher, like 100 to 250+. Lately though, in the last few weeks, the Airthings is like 20 over or 20 under or spot on. I wonder if Airthings did an update because that's a drastic change.
Yeah Airthings always drops like a rock, eventually will be way off within a couple more weeks. Not good. I usually calibrate them "aka setting them outside for 30 mins" once a month to keep them relatively accurate. Otherwise they're way off.
Yup. I have mine sitting next to my Airthings View Plus everyday now. The Aranet is wayyy more accurate for CO2 only because the Airthings you have to calibrate it every 2 weeks which is insanely annoying. Aka you have to take it outside for 10-20 mins every 2 weeks. Aranet, I always bring with it but it never needs it. It stays calibrated somehow. It's awesome. I might try going extended time without calibrating the Aranet to see how long it can go.
@@arielrodriguez6980 That’s different. That’s calibrating to your air on initial setup. But then it falls out of calibration every 2 weeks. It gets 100-200 low. So I have to calibrate it manually. You can read about it if you look up their manual
@@Slimothy That is correct. I called the co and they said what you said to take it outside weekly. I have the A4 now and it is nice that it is portable. I may keep it or return it. I figure suppose the Airthings is off by 100-300 when it displays 800 I can see it as it really is 900-1100.
@@arielrodriguez6980 It drifts. So I guess if you just want an estimate, that would be ok? I don’t trust it though that’s why I check my Aranet4 instead. I also have the new INKBIRD device which I believe uses the same sensor as the Aranet4. But I believe it’s owned by a Chinese company instead of European like Aranet4 so that will likely turn a lot of people off. But I’ll have a review of the INKBIRD up within a month. Slightly cheaper. I love the Aranet4 though. If I didn’t, I wouldn’t have bought my own!
@@barygol Eh. Pm 2.5 requires a fan. Would make this thing much larger and use a lot more energy. I think the price is fair. The INKBIRD is 50$ cheaper if you are ok with a Chinese company instead of European. We will have a review of it up soon.
Temperature sensor didn't work for me, I put it outside and temperature only dropped from 23C to 22C. My guess is it is picking up waste heat from circuit instead of ambient air temperature. I once worked on an IoT project and we had exactly that problem for embedded sensors, we have to use a wired analog temp sensor to get accurate measurement.
@@8749236 I have multiple of these and have extensively tested them and they are insanely accurate. I have a feeling you got a dud or something else is going on. Try doing a firmware update and make sure if it’s outside you leave it for about 30-60 mins to acclimate and set the refresh rate to 1 minute not 5. If it still doesn’t work reach out to Aranet.
@@MaxCaud Perhaps, there’s a lot of things I’d like for $200. But I can tell you whatever magic they put into these devices makes them the most accurate CO2 sensors we’ve tested. I actually bought another one with my own money from Amazon just to make sure Aranet didn’t give me a juiced up version. They both are so accurate. All of my other CO2 monitors fall out of calibration every 2 weeks or so. These do not. It’s fantastic.
@@barygol Great so your $200 CO2 sensor needs another piece of hardware to connect to the internet. The exact Sensair NIDR sensor they use is $40. Pressure, temperature and E-ink screen is nothing. For $200 they could of put a wireless module in it is the point....
@@b93kda I thought the same until I tested others on the market. This is the only one I trust. INKBIRD has a slightly cheaper one and it’s very close to this one. Besides this one and INKBIRD, I have 0 other CO2 meter recommendations.

Hey Slim, are you interested in trying out our View Plus air quality monitor?
Hey there, could you shoot an email over to us? On our RUclips channel about page we have our business email and we can get something going!
I have an air things indoor monitor, so I’d be interested in your review. I have it mostly for CO2 and radon
I’m very pleased with mine - it does exactly what it’s supposed to. I did all of my “research” within the first couple of days. The only real surprise for me was the buildup in the car; I’m not using “recirculate” anymore!

*What do you think of the SAF Aranet4 wireless indoor co2 and air quality monitor? For us, we think it's great and one of the best on the market!*
I have multiple and I wish there was a software update to allow you to add an offset to the humidity readings as I have one that is consistently 5% high.
@@mattweisz That is another thing they could add, good catch!
Thanks for the review, I'm a teacher and am getting this for my classroom.
Cheers! It’s a great little device
Have you tried the Inkbird CO2 monitor? Very similar to the Aranet4 (they use the same sensor).
Funny you say that -- they actually just dispatched one to our studio -- we should have it soon and will be testing it! Stay tuned, video will be coming too.
@Slimothy Awesome , looking forward to it!
@@Slimothycan you also check the Android app experience, as i think that iOS app is much refined on both Aranet4 and Inkbird
I had one, returned it right away. Got 2 Aranet4's. They're just nicer and more accurate.
7:24 not adjusted for elevation? It's a real time local sensor. Not sure what you mean✌️
Pressure needs your elevation to be accurate. This doesn’t allow that. Doesn’t really matter tho

Bingo. It's a great, solid device that is SUPER accurate in my tests so far.
Didn't feel cheap to me, it's just light. Had it been steel the price would have been $30 more. The Inkbird knock-off, now THAT felt cheap.

Thanks, I think I'm getting one. Followed your link.
Cheers 💯
What do you use as a carry case?
Nothing right now. I’m actually about to bring it on an international flight without a case

@@Slimothy Airthings needs to go outside once a week for calibration? I thought it auto calibrates the CO2 and VOC in 7 days.

What’s that
No PM2.5 nor Radon?
Absolutely not. That’s a weird question to ask when we literally go over every feature of the device 🤣
@@Slimothy It was more a critic to the product than a question. For the price tag it might as well bring at least a PM2.5 sensor.

No wifi, therefore you can’t monitor if away from home!
Correct. Though most circumstances you’d want this device where you’re currently at. Not much help if you’re away from the device!
