The quietest dehumidifier on the market will almost always be a desiccant dehumidifier. These dehumidifiers don’t have a compressor so you eliminate the biggest contributor to dehumidifier noise.
The problem is that desiccant dehumidifiers may be quiet but they’re really expensive. Also, they have far smaller capacities than the regular compressor type dehumidifiers do.
Don’t be too quick to discount regular compressor type dehumidifiers though. As technology has improved some of the best dehumidifier brands are producing really silent dehumidifiers in spite of having to use a compressor.
We’ve reviewed 5 of the quietest dehumidifiers, both desiccant and compressor type, and have listed their noise levels, features and links to updated pricing below.
Best Quiet Dehumidifier Reviews
It’s a desiccant dehumidifier so there’s no compressor noise. Pretty much the only sound you may hear is from the fan.
The fan has multiple speed settings. At its lowest setting you’ll get a noise level of an impressively quiet 34dB. Even at its highest fan setting you’ll still only be getting up to around 51dB or so.
And this dehumidifier is no slouch. Even though it is a desiccant dehumidifier it still has a decent capacity of 15-pints and will bring your room’s humidity all the way down to 45%.
We love the compact size and elegant look of this unit. The dehumidifier’s filter is pretty easy to clean and is a cinch to remove and replace.
The Classic model has your regular rotary controls and no fancy LED readouts on the control panel. We prefer the electronic control version (Classic model) of this dehumidifier but you’ll be paying a bit more.
We just love how whisper quiet this dehumidifier is. The capacity isn’t sufficient for a larger living space but it’s perfect as a bedroom dehumidifier and it won’t disturb your sleep.
With a capacity of 50-pints it will easily dehumidify the biggest bedroom and even medium to large living spaces.
As with the other dehumidifiers on our list it has multiple fan speed settings. At the highest fan speed it will only put out an impressive 52dB! That’s just about as quiet as the EcoSeb.
For a comparable price you get the same low noise output but with almost 4 times the capacity. It’s a little bulkier though so you’re going to need to find a good spot for it. It has an auto-restart function so all your settings wil still be in place after a power outage.
It also supports continuous drainage but you’ll have to buy a hose because it doesn’t come with one.
We didn’t like the squared off look of it much but we love how quiet it is.
At 30-pints it has twice the capacity of the EcoSeb while only being marginally noisier. At the highest fan speed setting you’ll be hearing a pretty quiet 53.3dB.
In fact, that difference of only 3dB means that your ears wouldn’t actually be able to hear the difference between this unit and the EcoSeb.
It has some great features too. There’s an alert to tell you when the water reservoir is full, auto-defrost for low temperature operation and auto shutoff function.
The digital controls are attractively arranged and simple to use.
It’s going to take up a little more space than a desiccant dehumidifier will but the performance makes it worth considering.
If you’re looking for a quiet dehumidifier to use in a medium sized space then this is a good option. In fact, taking its low noise level and great performance this is probably the best quiet dehumidifier for the money.
If you’re trying to dehumidify a large space that experiences high humidity then you need to aim for something with a 70-pint per day capacity. It’s still possible to find quiet dehumidifiers at this capacity.
This great dehumidifier gives you the performance you’re after while still remaining whisper quiet.
At its highest fan speed it only puts out 53dB. For a 70-pint dehumidifier that’s really impressive.
The electronic controls make it easy to operate and setting the desired humidity level is a breeze.
Because of the higher capacity it’s quite a bit heavier than some of the other dehumidifiers we’ve reviewed but the castors make it simple to move around and position.
The low temperature performance makes this dehumidifier a good choice for rooms that aren’t heated and that may experience lower temperatures in winter.
It will look good in any living space and when it’s switched on will remove up to 35-pints of moisture per day. It will do that fairly quietly too.
You get two different fan speed settings and at the highest setting it will produce around 58.2dB of noise. It’s a little noisier than the other options we reviewed but it has some nice features.
One of the biggest advantages of this dehumidifier is that it allows for continuous drainage. This means you can set it up with some simple plumbing and never need to empty the water reservoir.
It’s also Energy Star rated so it runs very efficiently.
It may not be quiet enough for the bedroom but it’s plenty quiet enough for your living space. Hisense also have excellent customer support for their products.
How To Make The Quietest Dehumidifier Even Quieter
Your best opportunity for the lowest noise is when you purchase your dehumidifier. Making a good choice gets you off to a good start. There are ways to reduce dehumidifier noise even further. There are some basic noise reduction techniques you could try. If you want quiet dehumidifiers with the lowest possible noise level then take the following into consideration:
Noise Sources – The fans and compressor (if it has one) will be your main noise sources. If the fan passes air over louvres that move automatically make sure that they don’t squeak when moving. A quick spritz of silicone spray should sort that out. Loose panels can also cause noise. Make sure that the dehumidifier panels are secure and can’t vibrate.
Fan Speed – For a dehumidifier to work effectively it needs to circulate all the air in the room through the unit. The larger the volume of the room, the faster the fans will need to spin. Higher fan speed means higher noise output. Your best bet is to use the high fan speed during the day and the low speed at night when you really need it to be quiet.
Capacity – If you buy a regular dehumidifier make sure that you’re not going overboard with the capacity. As the capacity of the dehumidifier increases so does the size of the compressor. A bigger compressor means more noise. (This is the same issue we discuss in our quiet generator post) Do your calculations beforehand to see exactly what capacity you need. There’s no need to buy a 70-pint dehumidifier when a 50-pint or even 35-pint one will suffice.
Location – As with any noise, the further you get from it the quieter it sounds. You want your dehumidifier to be in a space that makes it possible to shift the air through it. That doesn’t mean that it needs to be right next to where you sit or sleep though. A desiccant dehumidifier will be a lot more compact so it’s easier to fit into a smaller spot that may be out of the way and further from your sensitive ears.
Bedroom Dehumidifier – When you’re sleeping you need everything to be extra quiet. Even the quietest dehumidifier could still end up keeping you awake at night. Rather place the dehumidifier just outside your bedroom and keep your door open. It will still get the job done and you’ll get a good night’s sleep.
Surface – Make sure that you place the dehumidifier on a level surface. If the surface is uneven then you’re going to get vibrations and noise. If your room has wood floors then the vibrations from the dehumidifier could reverberate through the floor. Placing a piece of carpet under the dehumidifier will reduce the vibrations and noise.
Humidity Level – Your dehumidifier shouldn’t have to run all day. If you set the controls to maintain an ideal humidity level of around 40% to 50% it will cycle on and off throughout the day. That means you’ll have quiet periods and less quiet ones. If you set the humidity set point too low then it will never switch off and the air will be uncomfortably dry.
Air Filters – When your air filters get clogged up then your fan needs to work a whole lot harder to push the air through it. If you clean your air filters regularly then the fans can operate at a lower speed and a lower noise level.
The only time a dehumidifier is completely silent is when it’s off. Every dehumidifier, desiccant or compressor type, needs to shift air and that requires fans. If you buy a desiccant dehumidifier you end up with a small, low noise dehumidifier but with a high price tag and reduced capacity. That being said, they’re probably you best option if you want a bedroom dehumidifier.
If you want a quiet dehumidifier for a larger space then you’ll have to get one with a compressor. Make sure you spend a little more to get a good one like the ones we reviewed above. They really aren’t much louder than the desiccant type. During the day you can run them with high fan speed and when you absolutely need peace and quiet then just turn the dehumidifier fan down to low.
