After the first hour, I checked my room and can feel the difference. When the full 4 hours was up, I checked again and noticed that the humidifier was shut off as it is suppose to. The moisture level never seem to get passed 56/57%. I then let it run until all the water is used up, which it wasn't all used up. There are still some left in the base that you are not suppose to add water to. I filled up the water tank all the way again, being careful when removing it from the base. Some left over water may spill out. After putting it back on and setting the unit to auto, I let it operate. It didn't stop running, rather I don't know if it did at any point since I didn't check it regularly, for 24 hours after which the water in the tank ran out. The moisture reading never passed 56/57%, which may be a good thing for me. Being situated right next to my bed, the noise was not very noticeable with the occasional water gurgle from time to time as the unit ran.

Yeah snakes. Anyway just an update... i bought that small unit with the tank at the bottom and it’s only good at making water. Didn’t drop the humidity for my pets haha. But if u use it in a small closet it would help keep your clothes a little fresh, which is what I’m using it for now. Kinda worth the price actually.
It depends on where you are living, as to which type of dehumidifier you use. You can correct me if I'm wrong, but if you are somewhere in Southeast Asia, as I think you are, with high temperature and high humidity, your electric one is the best type to use, as they work better due to the temperature differential. The same type here, in the British Isles, works reasonably well during our summer months, but nowhere near as efficiently as where you are, for the same reason. Over here, the best type to use is the electric version of the second type that you displayed with the reusable dessicant beads, as it is the material in the beads, that draws the water out of the air, and not a temperature differential, allowing it to work all year round across a range of temperatures, however, in order to get the water out of the material, it needs to be heated and most of these dessicant type electric dehumidifiers use more electricity than the condenser type of an equivalent capacity.

@@joex8279the thing with desiccants is that they break within 2-3 years. Condenser based ones are much better and can last a decade easily. As long as the temperature is 10c+ they work very well, which is in almost all homes.
Most ppl just review how a dehumidifier works. But no one actually mention is it work on open environment like living room which air are coming in and out of the environment. As I know the most effective is a close environment which like dry box which had a build in dehumidifier build in. But also the large size dehumidifier power usage compare to Aircon Dry mode and how much heat it increase for the room temperature as the dehumidifier generate dry air by warm the air back out from the blower.
It’s not going to be effective if the room if there is lots of air circulation. Similar to how aircon will not be effective in such situation. Not sure how much heat a huge dehumidifier will give out. But humidity will make temperature feel relatively higher so the dehumidifier may give out heat but also reduces humidity to reduce relative temperature
@@teohontech7141 A dehumidifier will definitely cause an increase in the temperature, especially if it's in a small, enclosed space. In a larger space though, it will probably not be noticeable. It will also be a "dry heat" so it wouldn't necessarily be that uncomfortable. The heat produced by a dehumidifier comes from both the electrical energy used to run the compressor and the fan motors, as well as latent heat released by the condensation process (think evaporative cooling in reverse). At a room temperature of 22C (72F), a dehumidifier will put out 2,260 kJ (2140 BTU) for each liter (33.8 fl oz) of condensate it produces. For every kilowatt-hour of electricity consumed (500-Watt unit for 2 hours), it will also release 3600 kJ (3412 BTU).
0:40 That bit about moisture inside LCD panels is also a huge problem for me with vintage PC hardware! In fact, I have both a medium-sized dry cabinet and a large dehumidifier.
What is the humidity level you maintain? I had been using dehumidifier for nearly 15 years, and it worked great, but recently I moved a lot of stuff to storage shipping container as I had to leave rented flat and have problems, as expected, with high humidity. I have 2.4 kW solar and recently supplemented it with Hyundai 2 kW inverter generator, because it is winter and I can't charge batteries to sufficient level to support dehumidifier. I am hoping to maintain 70% (ideally
@@kbhasi I am considering upgrading my 250 watt compressor dehumidifier or getting some heating in the container. I don't want to run the generator too much, as petrol gets expensive. Moreover, it isn't possible to close the door from inside, so every time I open the container I am risking undoing all the work. Sounds like lost cause, to be honest, but I am experimenting with off-grid life style anyway. What do you keep in the dry cabinets?
@@pavel9652 Vintage laptops and monitors that are small enough to fit. Both dry cabinets I have have around 38 cm or 15" wide interior size (exterior is around 40 cm or 15¾" wide) and have a similar depth, so they can hold upwards of laptops with 15" 4:3 displays. I could probably list some examples of the stuff I do keep in there if you want. The upper cabinet, which has the same width but a shorter height and depth compared to the lower cabinet, doesn't have a humidistat and runs off an external power supply. That one already defaults to 40% humidity. The lower cabinet does have an internal power supply and humidistat, but it has a flaky humidistat at that and is currently at around 20% humidity. As I can't get to the humidistat because it's all the way at the back of the interior, I can't change it, and I can't remember if I had intentionally set it to 20% some years back or if I had accidentally bumped it at some point in time. I forgot to mention this but I live in a country that has a humid climate, so it's rarely cold here. I assume that by "heating", you're referring to a split system air conditioner, but correct me if I'm wrong.
right now in uk past month it has been 80% and above. We get 23'C somtimes sun and 23'C sometime rains. Remind me when I am in asian country. Very annoying humidity
I use passive one inside a tight container with a meter to measure humidity when it goes above 45% i recharge it it lasts a month in a closed container. It is the best if u dont open container often.
This is perfect I was just looking for dehumidifier so I check ytb. Finally I find an english speaking video I start watching and oh wait this is the guy with the graphic tablets :D anyway I almost bought that off brand xiaomi, Bt speaker looking like one but you convinced me that the active electric is more worth it.
*We liked it **Fastly.Cool** so much in the basement, we bought a second one for the main level. The amount of moisture it pulls out of the air is astonishing.*
The relationship between humidity and temperature is complex. What's ideal for humans is good for mold and bacteria. However there's a range where it's good for humans and bad for mold/bacteria but it's not a single number it's a scale between temp and humidity. At 35% humidity you become a capacitor and start shocking yourself everytime you ground yourself. So between 35-40% is best for stopping bacteria. So in F, at 80° F< we'd want the humidity to be between 35-40%. However at 50°F bacteria doesn't grow well or at all and you can raise the humidity to 60%.
That active dehumidifier is a Peltier cooler, it works on temp difference, when electricity is applied to the Peltier plate it heats one side and cools another, heat is removed by a fan and cool side condenses water. If you are worried about electricity bills then buy a solar panel and connect it to a DC Peltier (I'm sure sm1 must have made it on yt) since you live in Malaysia u'll be getting sun most of the year.
Thanks for explanation. I was pretty sure this is what the device was equipped with. Compressor dehumidifier will work better, as they are more efficient. He has a good temperature difference and the air is warm and moist. At the end of the day, what matters is that condensing water vapour takes a lot of energy, so power rating of the unit matters.
@@pavel9652 yeah that is more efficient but I'm not sure if those compressor ones would be under every1s budget. A 100 watt solar panel + the dehumidifier would be cheap enough to maintain livable conditions especially for the price concious
They don't turn into water. They absorb the water and get dissolved in it which means that the liquid below is a mixture of water and the silica. Also, the beads are often refillable so you don't need to keep on buying new ones. I would pick buying bead refills over having an inflated electric bill.
Those dehumidifiers suck I suggest getting a Midea they are great 👍 you will not be disappointed and you can tell a difference immediately very powerful mine filled up half way with water from the humidity in the air in two hours from 9:15-11:21 and it’s also blue tooth and WiFi connected you can control it from you home and you will have to empty every 8
@@teohyc Finally, someone with a scientific approach. Thanks a lot. Lots of the review does not have a sustain environment with numbers to test. This is the first video that's showing everything. You did a great job :D
Agree! He did a great job. I bought a semi big one for my bedroom with two liter of capacity. But I have to replace it a few times every day. I am also trying out the smaller ones. Lastly, I think it will stay humble in the wardrobe throughout its life. No one likes a cocky dehumidifier😉
I bought the Xiaomi Deerma Mini Portable Dehumidifier also. I read a comment that say "The advantage of silica gel is that it can be heated again when it is saturated with water without changing shape. But funnily enough, if the heating is done in the same room, it means you release the water vapor that's been caught back into the room.". I usually charge it inside my bedroom, any idea if during charging the water inside is it really released back to the room?
@@teohontech7141 Yes, as the official ad recommends it's usage at a mere 385cm³ which is smaller than a small cabinet. For reference, my moderate sized 5m×9m×3m room is already 135,000,000cm³
Get a Midea I was skeptical for the money but oh my goodness I had to empty the water filled up in 8 hours from the moisture in our house and watch a video Midea 22pint dehumidifier
I just bought this one and noticed instantly with the air quality and completely stopped mold growth here is the video I was talking about ruclips.net/video/w9DBXoWSsTw/видео.html
Here in Singapore it’s too humid. 75% humidity so it’s kinda pointless to have it out in the open even if it’s under the sun. That and it takes really long for the water to escape
@@teohontech7141 i have a humidifier which is a big 40 litre one, i recommend going for expensive over cheap because the tank is bigger and since its bigger so is the condenser inside it and the fan so it can do heating too. On FB marketplace in the summer these big ones get cheaper
The last one pillow-like is great in cars in my opinion here UK. Especially the larger ones, it prevents steamy windows and when its full you just throw it in microwave.
1. Is the 3:30min electric dehumidifier noisy, is it louder than fan or air con? 2. Will the electric dehumidifier auto stop if it detects the water tank is full of water already, how does it alert you to empty the tank? 3. I think it comes with a water tube/hose, is it you could attach the tube to the water tank (I see a round back rubber covering a hole at the top) then you can drain the water to a big pail so no need to empty the water tank so often? I guess is the water tank needs to be full of water then water will flow out from the tube. Thanks.
Noise is audible. Louder than aircon silent mode. The humidifier will stop by itself when tank is full. There are dehumidifers that have draining pipes
Are there wireless electric dehumidifier (like the one at 3:30min that has water tank) that do not require wired to electric socket when in use or maybe can recharge then use? I intend to put inside wardrobe/cupboard that has doors, inside the wardrobe no 3 pin plug socket. Thanks.
A mix of that and little desiccant packets in the boxes or around my stuff keeps them dry and the damprid helps the desiccant last longer before needing replenishing in my food dehydrator
Probably the one container with beads that you have to replace. That's if you have space inside the piano that lets you put and take the container out easily.
Just buy the dispodable one and when the beads are no longer effective, you can just refill it with calcium chloride :) You can buy calcium chloride at pool stores.
Should also explain that dehumidifiers differs in method and which temperature they are most effective. Example a condenser dehumidifier is not effective at colder temperatures as a desiccant dehumidifier etc.
I did not measure the non-electric ones. But for the electric ones, the humidity will drop to 50%+ for my cupboard, and go up to 75% when I open the cupboard for long period of time.
thanks for the video. how do you empty the water btw? do you remove the white part that covers the tank? or remove the black silicone stopper on the corner? also how do you clean the tank itself? thanks so much.
Thank you. I watched a tear down video of the device and saw that it contains a regular PC-type brushless fan. These fans are noisy and wear out quickly...
A dehumidifier does not kill the mold. The dehumidifier will remove water vapor in the air so that your chances of getting getting mold decreases. As mentioned in the video, you also need to choose the right size dehumidifier for the job. Those shown in this video are for small spaces likes closets or baths. Hope this helps.
@@makaveli2tt hi I used scented dehumifers they say they can be used in home wardrobe and cars and I use mini moisture traps and wardrobe dehumifers are dehumifers worth using and are they ok to use if u have visible mold in a bedroom also can I use salt when Crystal's have run out
@@taramiller70 if you have visible mold, you need to get rid of that first. Depending on how much mold you have and what type of mold is visible, you may need to call in a specialist or you can do the removal yourself with some mold and mildew remover from the hardware. Be sure to properly prospect your eyes, nose, mouth, hair and skin if you choose to do the job yourself. Mold spores can cause adverse effects on your health. As for using salt... This will not have any effect on the mold as the mold will continue to feed on moist air in your room. Dehumidifiers are worth it although you may need a bigger more powerful dehumidifier than those you mentioned if your humidity level in your room is really bad (constantly over 60%). Get a hygrometer to monitor your humidity they are cheap at under $20. Also, once you get the mold cleaned, try to get fresh air to circulate into and out of your room. Try rearranging some furniture or keep doors and windows open more often. If you have any water leaks/seepage near the room get that fixed also. Moist AND stagnant air is the main cause for indoor mold. Hope this helps.
@@makaveli2tt what about calcium chlorine the Crystal's in dehumifers I brought two packs of them also can i still continue using dehumifers I have the big dehumifers are expensive also I watched a video on here and someone used salt in their dehumifer as damp trap trick
One observation, at the beginning of the video you had air conditioning and humidity dropped to 40%, is that enough? does the air pump (whether to cool or heat) behaves like a dehumidifier for big room?
Usually there's info provided on how big an area the dehumidifier can serve. The small one I have is good for use inside cupboards but not for rooms. 40% is good for me because the high humidity here is 70+
@@moonbreon if your ac drops the humidity to 40% and then it quickly rises when it cycles off is usually a sign your ac is too powerful. When this occurs, instead of a dehumidifier, get the smallest BTU window AC you can get that will run non-stop to get it just barely cool enough to be comfortable . That will reduce the humidity. The only difference between AC and dehumidifiers are that ACs blow hot air outside. Dehumidifiers simply mix that hot air with the cold air and send in all into the room.
Bought 2 of the smallish ones like on the left here. Running for an hour and not one drop... One in hallway and one on landing upstairs and nothing! House is average 65-80%. Any insight? They look decent enough but no moisture is coming through
Thank you for this video, I have been looking at mostly north american settings.for.dehumidifier goot thing I found one closer to my setting in the Philippines. Does the humidifier work better when doors and windows are closed? I am thinking of getting one for my room.in order to minimize use of airconditioners. Thanks.
Thanks for the info, you mentioned humidity level is better below 60%, does it same with room at singapore as well? i bought the meter and show consistent of 70 - 75% in my room. Do that consider high? I am also confused sometime, if the room humidity level is low, we might have a dry throat when sleeping and consistent needs drinking at midnight... and if the humidity is high, it might have several side effect?
70-75% is considered high. The dehumidifier is mostly to prevent damage due to humidity, prevent mold growth. Not sure if lower humidity will result in dry throat, maybe if your mouth is open when asleep but the thing is even if it's 70-80% typical humidity in Singapore, you can get dry throat too if your mouth is open when asleep. There's not much reason to use dehumidifier for a room. And if you want to dry a room, you'll need a much larger dehumidifier than the small electric one shown in the video. Some people use dehumidifier to dry the room because they want to dry clothes, or their skin don't react well with humidity.
Did the beads turn black after 1 day because it was closed inside of a bookshelf? Is there a chance that maybe it was merely pulling moisture out of the wood?
One of my watercolor sets get moldy for when I don't use it. I use a silica gel pack, but it still gets mold. My guess it's perhaps it has collected enough moisture, or it's expired. A dehumidifier is a nice way for this, as it gets humid where I'm from. So far, my mom is telling me to open the windows to make it less humid.
Silica absorbs circa half if its weight of water vapour, so it is tiny amount, few drops of water. They were designed to protect products in plastic bags during shipping.
You can think of it that way. Or it could be the water holding capacity is low which is why it turns black fast. And it will be inconvenient to recharge that often
@@teohontech7141 i meant, which one is it? Is it very effective at absorbing moisture or does it have a low storage capacity? Your video would be so much more valuable if you had pointed it out. Have fun!
@@TheAllMightyGodofCod The ones that connect to power outlets will be most effective because they are working all the time and no re-charging of beads, or changing out beads is required.

Is the active one good for small rooms? I always have 50% to 90% humidity in my room and because of that I'm always sweaty. I live in the Philippines which is a tropical country. The condensation thing on the active dehumidifier is called a Peltier cooler. Which have other side going hot and other side going cold. I think the cold side condense the water in the air which reduce moisture.
Just bought a dehumidifier because it's way too hot here at night in the u.k 30oc in the day 25 at night hard to sleep will one of these actually help? I always get mixed up with dehumidifier and humidifier lol
Dehumidifier dries the air to prevent moisture damage, eg mold. Humidifier provides more moisture to the air, eg to prevent dry skin. To control temperature, you should get an air conditioner that you can use to adjust temperature. You can’t adjust temperature with dehumidifier
Hi Teoh! It' been one year now. Is the device still working? I'd love to buy a similar model (the electric one with a blue tank) at home that's worth the price.
Unfortunately mine broke down. I bought another one. Go with the smaller units but with larger water capacity so that you don’t have to pour out the water often.

At a room temperature of 22C (72F), a dehumidifier will put out 2,260 kJ (2140 BTU) for each liter (33.8 fl oz) of condensate it produces. For every kilowatt-hour of electricity consumed (500-Watt unit for 2 hours), it will also release 3600 kJ (3412 BTU).
0:40 That bit about moisture inside LCD panels is also a huge problem for me with vintage PC hardware! In fact, I have both a medium-sized dry cabinet and a large dehumidifier.
What is the humidity level you maintain? I had been using dehumidifier for nearly 15 years, and it worked great, but recently I moved a lot of stuff to storage shipping container as I had to leave rented flat and have problems, as expected, with high humidity. I have 2.4 kW solar and recently supplemented it with Hyundai 2 kW inverter generator, because it is winter and I can't charge batteries to sufficient level to support dehumidifier. I am hoping to maintain 70% (ideally
@@pavel9652
Usually around 60% humidity for the large dehumidifier and around 40-50% for the dry cabinets.
@@kbhasi I am considering upgrading my 250 watt compressor dehumidifier or getting some heating in the container. I don't want to run the generator too much, as petrol gets expensive. Moreover, it isn't possible to close the door from inside, so every time I open the container I am risking undoing all the work. Sounds like lost cause, to be honest, but I am experimenting with off-grid life style anyway. What do you keep in the dry cabinets?
@@pavel9652
Vintage laptops and monitors that are small enough to fit.
Both dry cabinets I have have around 38 cm or 15" wide interior size (exterior is around 40 cm or 15¾" wide) and have a similar depth, so they can hold upwards of laptops with 15" 4:3 displays. I could probably list some examples of the stuff I do keep in there if you want.
The upper cabinet, which has the same width but a shorter height and depth compared to the lower cabinet, doesn't have a humidistat and runs off an external power supply. That one already defaults to 40% humidity.
The lower cabinet does have an internal power supply and humidistat, but it has a flaky humidistat at that and is currently at around 20% humidity. As I can't get to the humidistat because it's all the way at the back of the interior, I can't change it, and I can't remember if I had intentionally set it to 20% some years back or if I had accidentally bumped it at some point in time.
I forgot to mention this but I live in a country that has a humid climate, so it's rarely cold here. I assume that by "heating", you're referring to a split system air conditioner, but correct me if I'm wrong.
Thank you for sharing. I found the final piece of information on how to build a cabinet to house all my collectables!
In Indonesia, we need to use dehumidifier, because RH is so high around 70-90%
right now in uk past month it has been 80% and above. We get 23'C somtimes sun and 23'C sometime rains. Remind me when I am in asian country. Very annoying humidity
Thank you. I was about to purchase the deerma. I'll be looking for one of those "active" dehumidifiers.
I use passive one inside a tight container with a meter to measure humidity when it goes above 45% i recharge it it lasts a month in a closed container. It is the best if u dont open container often.
thank u so much for this video! really helped give me an insight into what kind of humidifiers to get for my house :D
This is perfect I was just looking for dehumidifier so I check ytb. Finally I find an english speaking video I start watching and oh wait this is the guy with the graphic tablets :D anyway I almost bought that off brand xiaomi, Bt speaker looking like one but you convinced me that the active electric is more worth it.
i got the box dehumidifier and never understood how it works until i check it today theres some water in it and i was shocked 😳😳
Idyot
*We liked it **Fastly.Cool** so much in the basement, we bought a second one for the main level. The amount of moisture it pulls out of the air is astonishing.*
The relationship between humidity and temperature is complex. What's ideal for humans is good for mold and bacteria. However there's a range where it's good for humans and bad for mold/bacteria but it's not a single number it's a scale between temp and humidity. At 35% humidity you become a capacitor and start shocking yourself everytime you ground yourself. So between 35-40% is best for stopping bacteria. So in F, at 80° F< we'd want the humidity to be between 35-40%. However at 50°F bacteria doesn't grow well or at all and you can raise the humidity to 60%.
That active dehumidifier is a Peltier cooler, it works on temp difference, when electricity is applied to the Peltier plate it heats one side and cools another, heat is removed by a fan and cool side condenses water.
If you are worried about electricity bills then buy a solar panel and connect it to a DC Peltier (I'm sure sm1 must have made it on yt)
since you live in Malaysia u'll be getting sun most of the year.
Singapore.
Yep, Malaysia here. Out side is already 60-70%, so my room coupled with a bathroom makes me suffer at 70-90% humidity 🥵
Right! Peltier model is the best to use. Also, library and music and instrument room can use those beads and portable dehumid aircond
Thanks for explanation. I was pretty sure this is what the device was equipped with. Compressor dehumidifier will work better, as they are more efficient. He has a good temperature difference and the air is warm and moist. At the end of the day, what matters is that condensing water vapour takes a lot of energy, so power rating of the unit matters.
@@pavel9652 yeah that is more efficient but I'm not sure if those compressor ones would be under every1s budget. A 100 watt solar panel + the dehumidifier would be cheap enough to maintain livable conditions especially for the price concious

Still, good content.
They don't turn into water. They absorb the water and get dissolved in it which means that the liquid below is a mixture of water and the silica.
Also, the beads are often refillable so you don't need to keep on buying new ones. I would pick buying bead refills over having an inflated electric bill.
The beads are not silica, it’s calcium chloride. Silica can’t be dissolved in water
Unless you can get the dessicant for free, electric dehumidification is cheaper by far.
Those dehumidifiers suck I suggest getting a Midea they are great 👍 you will not be disappointed and you can tell a difference immediately very powerful mine filled up half way with water from the humidity in the air in two hours from 9:15-11:21 and it’s also blue tooth and WiFi connected you can control it from you home and you will have to empty every 8

Agree! He did a great job. I bought a semi big one for my bedroom with two liter of capacity. But I have to replace it a few times every day. I am also trying out the smaller ones.
Lastly, I think it will stay humble in the wardrobe throughout its life. No one likes a cocky dehumidifier😉
the best way i think is to just install ac. cool the room and dehumidify.
I bought the Xiaomi Deerma Mini Portable Dehumidifier also. I read a comment that say "The advantage of silica gel is that it can be heated again when it is saturated with water without changing shape. But funnily enough, if the heating is done in the same room, it means you release the water vapor that's been caught back into the room.". I usually charge it inside my bedroom, any idea if during charging the water inside is it really released back to the room?
In theory, it will release the water back into the air. Anyway, the mini dehumidifier is meant to be used in small enclosed areas, not for rooms.
@@teohontech7141 Yes, as the official ad recommends it's usage at a mere 385cm³ which is smaller than a small cabinet.
For reference, my moderate sized 5m×9m×3m room is already 135,000,000cm³
Have you seen any difference in mold growth after using dehumidifiers?
Use a ozone machine if you've got a mold problem. Clean all surfaces. And then a dehumidifier will keep it at bay for awhile.

To revitalize the gel put it in the sun it will shrink then you can use it again.
Here in Singapore it’s too humid. 75% humidity so it’s kinda pointless to have it out in the open even if it’s under the sun. That and it takes really long for the water to escape

The last one pillow-like is great in cars in my opinion here UK. Especially the larger ones, it prevents steamy windows and when its full you just throw it in microwave.
1. Is the 3:30min electric dehumidifier noisy, is it louder than fan or air con? 2. Will the electric dehumidifier auto stop if it detects the water tank is full of water already, how does it alert you to empty the tank? 3. I think it comes with a water tube/hose, is it you could attach the tube to the water tank (I see a round back rubber covering a hole at the top) then you can drain the water to a big pail so no need to empty the water tank so often? I guess is the water tank needs to be full of water then water will flow out from the tube. Thanks.
Noise is audible. Louder than aircon silent mode. The humidifier will stop by itself when tank is full. There are dehumidifers that have draining pipes
Are there wireless electric dehumidifier (like the one at 3:30min that has water tank) that do not require wired to electric socket when in use or maybe can recharge then use? I intend to put inside wardrobe/cupboard that has doors, inside the wardrobe no 3 pin plug socket. Thanks.
Not that I remember
Informative. Thanks!
I have 5 damprid containers with the white shards in it around my room, it stays around 35-40% and tops at 55% when I sleep.
A mix of that and little desiccant packets in the boxes or around my stuff keeps them dry and the damprid helps the desiccant last longer before needing replenishing in my food dehydrator
Can you give me a link to the active dehumidifier that uses electricity? I can’t find it :(
i find the electric one in shopee
An excellent review and overview. Thanks!
What would be good for the living room.
Nice comparison, could you please also link the hygrometer (or tell us a brand and model) please. I haven’t seen this model and I like it
I can't remember where I bought this. Anyway, this is a rather generic hyprometer
which one would you recommend for me to put in my piano
Probably the one container with beads that you have to replace. That's if you have space inside the piano that lets you put and take the container out easily.
Would u save more money using the box with the beads than buying the electric, because the electric would use electricity and it adds up?
Just buy the dispodable one and when the beads are no longer effective, you can just refill it with calcium chloride :) You can buy calcium chloride at pool stores.
I like the device you have to check the humidity level. Can you share the link of that product and for how much you got it. Thanks
Bought that too long ago. Just search for hygrometer. Not too expensive.
Should also explain that dehumidifiers differs in method and which temperature they are most effective. Example a condenser dehumidifier is not effective at colder temperatures as a desiccant dehumidifier etc.
Is it ideal for hotter temperatures though?...
Excellent video I had no idea there’s was a difference between dehumidifier and humidifier.
Does one use a dehumidifier to perspire less but save money from otherwise using an air conditioner?
Informative but is there any measurements of the humidity levels after "x" hours in the cabinet between the different dehumidifiers you have?
I did not measure the non-electric ones. But for the electric ones, the humidity will drop to 50%+ for my cupboard, and go up to 75% when I open the cupboard for long period of time.
How many watts is the electric dehumidifier. Does it have an internal fan ?
Not sure on the watt. There is a fan
thanks for the video. how do you empty the water btw? do you remove the white part that covers the tank? or remove the black silicone stopper on the corner? also how do you clean the tank itself? thanks so much.
Remove the black silicon stopper to drain out the water. I’ve not tried cleaning the tank yet. So far after a few months the tank seems very clean
@@teohontech7141 thanks so much for the tip!

@@RandomNullpointer Don't PC fans last for years?
Do dehumifers kill mold already in a room or stop new mold appearing
A dehumidifier does not kill the mold. The dehumidifier will remove water vapor in the air so that your chances of getting getting mold decreases. As mentioned in the video, you also need to choose the right size dehumidifier for the job. Those shown in this video are for small spaces likes closets or baths. Hope this helps.
@@makaveli2tt hi I used scented dehumifers they say they can be used in home wardrobe and cars and I use mini moisture traps and wardrobe dehumifers are dehumifers worth using and are they ok to use if u have visible mold in a bedroom also can I use salt when Crystal's have run out
@@taramiller70 if you have visible mold, you need to get rid of that first. Depending on how much mold you have and what type of mold is visible, you may need to call in a specialist or you can do the removal yourself with some mold and mildew remover from the hardware. Be sure to properly prospect your eyes, nose, mouth, hair and skin if you choose to do the job yourself. Mold spores can cause adverse effects on your health. As for using salt... This will not have any effect on the mold as the mold will continue to feed on moist air in your room. Dehumidifiers are worth it although you may need a bigger more powerful dehumidifier than those you mentioned if your humidity level in your room is really bad (constantly over 60%). Get a hygrometer to monitor your humidity they are cheap at under $20. Also, once you get the mold cleaned, try to get fresh air to circulate into and out of your room. Try rearranging some furniture or keep doors and windows open more often. If you have any water leaks/seepage near the room get that fixed also. Moist AND stagnant air is the main cause for indoor mold. Hope this helps.
@@makaveli2tt what about calcium chlorine the Crystal's in dehumifers I brought two packs of them also can i still continue using dehumifers I have the big dehumifers are expensive also I watched a video on here and someone used salt in their dehumifer as damp trap trick

Good and helpful video.
How laud is the electrical one? Can you use it while sleeping?
Difficult to describe accurate. Maybe sound of a fan at light to medium speed?
One observation, at the beginning of the video you had air conditioning and humidity dropped to 40%, is that enough? does the air pump (whether to cool or heat) behaves like a dehumidifier for big room?
Usually there's info provided on how big an area the dehumidifier can serve. The small one I have is good for use inside cupboards but not for rooms. 40% is good for me because the high humidity here is 70+
@@moonbreon if your ac drops the humidity to 40% and then it quickly rises when it cycles off is usually a sign your ac is too powerful. When this occurs, instead of a dehumidifier, get the smallest BTU window AC you can get that will run non-stop to get it just barely cool enough to be comfortable . That will reduce the humidity. The only difference between AC and dehumidifiers are that ACs blow hot air outside. Dehumidifiers simply mix that hot air with the cold air and send in all into the room.

Purifier. May work.
Thanks for the info, you mentioned humidity level is better below 60%, does it same with room at singapore as well? i bought the meter and show consistent of 70 - 75% in my room. Do that consider high? I am also confused sometime, if the room humidity level is low, we might have a dry throat when sleeping and consistent needs drinking at midnight... and if the humidity is high, it might have several side effect?
70-75% is considered high. The dehumidifier is mostly to prevent damage due to humidity, prevent mold growth. Not sure if lower humidity will result in dry throat, maybe if your mouth is open when asleep but the thing is even if it's 70-80% typical humidity in Singapore, you can get dry throat too if your mouth is open when asleep.
There's not much reason to use dehumidifier for a room. And if you want to dry a room, you'll need a much larger dehumidifier than the small electric one shown in the video.
Some people use dehumidifier to dry the room because they want to dry clothes, or their skin don't react well with humidity.
Did the beads turn black after 1 day because it was closed inside of a bookshelf? Is there a chance that maybe it was merely pulling moisture out of the wood?

As a sportscard collector living in SEA, these humidifiers save my investment hahaha
One of my watercolor sets get moldy for when I don't use it. I use a silica gel pack, but it still gets mold. My guess it's perhaps it has collected enough moisture, or it's expired. A dehumidifier is a nice way for this, as it gets humid where I'm from.
So far, my mom is telling me to open the windows to make it less humid.
The silica gel has a limited to how much moisture it can absorb. Ventilation will help prevent mould
Silica absorbs circa half if its weight of water vapour, so it is tiny amount, few drops of water. They were designed to protect products in plastic bags during shipping.
But if it turns black over night doesn't it mean that it is very effective and it collected a good amount of moist in a short time?
You can think of it that way.
Or it could be the water holding capacity is low which is why it turns black fast. And it will be inconvenient to recharge that often

Is the active one good for small rooms? I always have 50% to 90% humidity in my room and because of that I'm always sweaty. I live in the Philippines which is a tropical country.
The condensation thing on the active dehumidifier is called a Peltier cooler. Which have other side going hot and other side going cold. I think the cold side condense the water in the air which reduce moisture.
You need to get a bigger one that's suitable for drying a room.
Does dehumidifier also prevents corrosion?
Ofc, one of the cause of corrosion is humid
does the electric or the charcoal one lower the humidity from 64 to 40%???

Dehumidifier dries the air to prevent moisture damage, eg mold. Humidifier provides more moisture to the air, eg to prevent dry skin. To control temperature, you should get an air conditioner that you can use to adjust temperature. You can’t adjust temperature with dehumidifier
