What is the quietest dehumidifier?

When it comes to dehumidifiers quietest doesn't always mean best. We've reviewed the 5 quietest dehumidifiers that actually perform. These have the lowest noise output and are the best quiet dehumidifier options for the money.

1. EcoSeb DD122EA-SIMPLE Quiet Desiccant Dehumidifier, 15-Pint

Quietest Dehumidifier

When it comes to being whisper quiet then the DD122EA-SIMPLE from EcoSeb is the best combination between being the quietest dehumidifier and being effective. Being a desiccant dehumidifier means there’s no compressor so if you manage to hear anything at all it’s only the fan.

At low fan speed the sound level is at a really low 34dB which is lower than anything else we’ve seen. At high fan speed it only gets up to 51dB. This low noise level makes it perfect for the bedroom. It doesn’t compromise on performance either and it’ll easily get your humidity down to around 45%.

The filter is really easy to remove and simple to clean as well. It has an auto-restart function so it will start up automatically with all your settings after a power failure. This unit is a great choice if you're looking for quiet dehumidifiers for bedrooms. While some desiccant dehumidifiers can be a little on the expensive side this one is really well priced and the quietest dehumidifier we reviewed with a really low noise output.

Quiet Dehumidifier - Frigidaire FFAD5033R1

Shhh. Did you hear that? Probably not. The spot for quietest dehumidifier is almost a dead heat between this unit and the one above. These compressor based units are ultra quiet dehumidifiers and they work extremely well and have extremely low noise output levels.

What really makes this unit stand out is that it has adjustable fan speeds. This means that when you want it to work hard you can turn it up and when you want it to be quieter you can turn the fan speed down. At high fan speed the noise level is 51dB which is really quiet compared to other big brand units.

The bucket pulls out conveniently from the front but it also supports continuous drainage if you connect a hose to the outlet at the back. This makes it ideal as a quiet basement dehumidifier. The castor wheels and handles make it really easy to move around too.

Quiet Dehumidifier - Keystone KSTAD50B

Not only does this dehumidifier get rid of humidity in a hurry, it also does it really quietly. And for a bedroom dehumidifier quietest is best. At high fan speed the noise level is about 52dB. It will remove 50 pints of water a day from a space of up to 3000 feet which makes it perfect for an open plan living space.

It also supports continuous drain function if you connect a hose (not supplied) to the outlet. It doesn’t have a built in pump so you have to rely on gravity and make sure the end of the hose is lower than the outlet.

The auto-restart function means that it will start up again with your settings after a power failure without you having to touch it.

Quiet Dehumidifier - RCA RDH705

If you’re trying to dehumidify an area less than 4,500 square feet and you want to do it quietly then this is the piece of equipment you need. When the fan is running at high speed it only generates 53dB of noise which is pretty amazing.

While this unit doesn’t make a lot of noise it is really effective. It’s fairly compact and, while it isn’t the lightest, the castors do make it easy to move around from room to room.

The controls are easy to use and the auto-reset function means it will start up after a power failure with the settings you entered. It’ll keep working even if the temperature gets down to 11 degrees so it’s a good option for the garage or basement as well.

Quiet Dehumidifier - SPT SD-52PE

While it’s not as quiet as the other units we reviewed this is a great compromise between quiet and effective. At high fan speed the noise level is 58.5dB which is still way below the dehumidifier noise level of a lot of other top brand dehumidifiers.

It will switch off automatically when the bucket is full and indicate that it needs emptying. It also has a built-in pump if you prefer to attach a hose to the outlet.

The pump makes it possible to pump away the water by running the hose (supplied) up through a window or into a sink. This way you never have to empty the bucket.

The controls allow for setting the desired humidity level to between 35% and 85% in increments of 5%. This unit is also Energy Star rated so it's very efficient.

​Quiet Dehumidifier - Noise Sources

​If you're looking for a really quiet dehumidifier then it's important to identify and eliminate the sources of the noise. Because every effective dehumidifier will generally have some moving parts you can't eliminate every source of sound but you can reduce their noise output. Here are the main noise sources to focus on:

Compressor Noise - Compressor type dehumidifiers will be your loudest dehumidifier options but they are also the most effective. If you want the quietest dehumidifier while still being able to dehumidify a large space you've got to go with a compressor. By making sure that the capacity of the dehumidifier isn't bigger than you need you limit the size, and noise, of the dehumidifier.

Desiccant Dehumidifier - With no compressor these are the most silent dehumidifier options available. These are also great dehumidifiers to use in really cold weather. Regardless of the fact that there's no compressor you're still going to hear it a little bit because of the fans.

Fans - Whether the dehumidifier has a compressor or not, it will have a fan. A good quality fan with decent bearings will be pretty quiet but you'll still hear it a little. Buy a dehumidifier with multiple fan speed settings. That way you can select the slow speed when you want it to be really quiet.

Louvres - If your dehumidifier has louvres that move automatically they can eventually make a slight squeak. If that's the case a drop of oil on the hinges should do the trick to make it quiet again.


Some people may say that there are quieter dehumidifiers with lower noise outputs available but the reviews above list quiet dehumidifiers that actually perform. There’s no point buying one that you can’t hear if doesn’t work properly either. The best dehumidifiers aren't always the quietest. If you absolutely need silence then get a desiccant dehumidifier but don’t expect it to work effectively in large open spaces unless you’re willing to spend some serious bucks. The refrigerator (compressor) type options above are your best bet if you want a good compromise between silence and performance. If you don’t want your peace disturbed by the sound of a compressor and fan then make sure you get a whisper quiet dehumidifier like the ones we recommend above.
