Dehumidifiers maintain optimal indoor air quality prevent mold growth, and reduce odors. But you didn’t bargain for a jet engine noise! So what’s the quietest dehumidifier? 

With modern technology and innovative design approaches, manufacturers have made significant strides in noise reduction. Today’s quietest models operate at sound levels comparable to a soft rainfall or gentle library whisper.

This article will take you through the best quiet dehumidifiers, covering both smaller and larger models. 

You’ll get a decibel (dB) comparison, as well as a description of the noise reduction technology and other notable features.

But first, how loud is a dehumidifier? The quieter dehumidifiers can register at under 50 dB, and below 40 dB. That’s a little louder than some of the quietest fridges, but quieter than a microwave or ceiling fan.

Before we get going, here are some stats on the chosen 7:

#1 – Waykar 2000 Sq. Ft Dehumidifier – 33 dB 

Here’s a rule of thumb – in general, the smaller the dehumidifier, the lower the noise. But while this Waykar Dehumidifier is compact, it can still remove moisture effectively from spaces up to 2,000 sq ft – those are larger spaces.

The 33 dB noise level makes it near-silent, and certainly one of the quietest we came across in the process of writing this article. The manufacturer puts the low noise level down to “advanced noise reduction technology”. What that means exactly, we aren’t sure – but at a lowest of 33 dB that will do for us!

Upgraded for 2024, the Waykar Dehimidifier derives its power from the latest rotary compressor technology. There are 3 adjustable fans speeds, an Energy Star ‘Most Efficient’ rating, built in child lock, and a timer. The unit offers a drying mode as well as dehumidifying.

Pros

• Very quiet (33 dB)
• Powerful
• Good value

Cons

• Users report it is heavy (but can be moved easily with wheels)

Best for: Very quiet mid-size dehumidifier

 #2 – HUMILABS Dehumidifier – 36 dB

If you are tackling condensation in your bathroom, or want to reduce humidity in another smaller room, chances are you don’t need a huge humidifier.

That’s where a small-size humidifier such as this HUMILABS Dehumidifier comes in. With a 2 L (about 4 pint) capacity, modest 10” x 8.6” x 18.5” dimensions it’s exactly what you need for a small space – and it’s quiet.

A noise level of 36 dB is very low and there is a timer which means the unit can automatically switch off and save you from wasting energy… and money. A small LED display allows you to read humidity levels, indicated by three color codes (blue, green, and red lights).

Pros

• Very low noise for size (36 dB)
• Easily maneuverable 
• Good value

Cons

• May be unsuitable for larger spaces

Best for: Bathroom or small bedroom

#3 – SIMSEN Dehumidifier – 35 dB

One more for the mid-size category – this SIMSEN Dehumidifier is fine for small to medium spaces, and its 35 dB noise level while in Sleep Mode means you can easily get some shut eye with it on. 

This is an upgraded dehumidifier that has added a filter and ionize to remove moisture and small particles from the air, keeping your dehumidifier running smoothly.

There is a colorful atmosphere light which gives you the choice of color – this can create a nice chilled or romantic ambience in your room without the need for another light. 

For its size, it’s pretty light at just over 2 pounds (lb), so you can easily move it around to the house to the room where you require it. There is also a handy auto shut-off feature which gives you peace of mind, preventing leaking or overflowing when the tank is full.

Pros

• Low noise (35 dB)
• Light weight
• Charming illumination 

Cons 

• May not be suitable for large spaces

Best for: Dehumidifying while you sleep

#4 – Hisense Portable Dehumidifier – 45 dB

If you live in a tropical climate, the Hisense Portable Dehumidifier is your friend. 

Able to dehumidify areas of up to 1,500 sq ft (that’s a large space), it has the power than you need to keep you comfortable, and prevent mold and mildew from forming. What’s more, for a dehumidifier of this size, it’s quiet – at 45 dB, the noise can go as low as some of the quietest fridges.

This is an Energy Star-certified dehumidifier that can remove an impressive 25 pints of moisture each day. There’s an automatic shut-off, which means when the internal bucket is full, the unit will turn off to avoid overflowing. Alternatively, you can connect a hose for continuous draining.

We must say – for the seller to call this portable is a bit of a stretch. Sure, you could put it in the boot of a car, but there are other dehumidifiers that are much more straightforward to move about. There are wheels and side handles to make this big boy easily maneuverable from room to room. And a washable filter makes for simple maintenance. 

If you need power without the sound of a jet engine; this is a dehumidifier to consider.

Pros

• Low noise for its power (45 dB)
• Can dehumdify large spaces
• Easy to move

Cons

• Not as quiet as some less powerful models

Best for: Studio apartment and large open pan living areas

#5 – AEOCKY Smart Dehumidifier – 45 dB

Going a bit less bulky and a bit quieter – this AEOCKY Smart Dehumidifier (which is great value by the way) registers at 44 dB, putting it comfortably in the quiet bracket. Reviewers are also almost unanimous that this is a quiet humidifier. 

With a 52-pint capacity, this is a dehumidifier that punches well above its weight and dimensions of 14.5” x 8.6” x 24.09” – it can perform dehumidifying duties for homes over 4,500 sq ft. That’s serious power.

AEOCKY calls its noise reduction technology ‘Arcticore’, and points out that at 45 dB it is significantly quieter than other dehumidifiers in its category. 

This AEOCKY Smart Dehumidifier ticks all the important boxes of quietness, power, and energy efficiency.

Pros 

• Quiet for its size and power (45 dB)
• Capable of dehumidifying large homes
• Sleek design
• Superb reviews

Cons

• Not as quiet as some smaller and less powerful units (but still quiet)

Best for: Large homes or spaces

#6 – Keepglad Dehumidifier – 30 dB

We really liked the cool modern design of this one; but we know that’s not all you are here for.

The Keepglad Dehumidifier is seriously quiet, registering as low as 30 dB. That is not enough to disturb even the most sensitive sleepers and chillers.

A capacity of just over 7 pints means that this isn’t the most powerful dehumidifier, but it can be effective in a space of 1,000 sq ft, and that covers most normal-sized rooms. So the Keepglad Dehumidifier is a safe bet to tackle your moisture problem and make your room more comfortable. 

Like a few of the models on this list, there is an automatic shut-off feature with red warning light. And also there is timer setting to avoid wasted energy. 

All-in-all, a very solid, very quiet option that looks the part and is pretty easily portable.

Pros

• Extremely quiet (30 dB)
• Cool design
• Powerful for size

Cons

• May struggle to do the job in large, open pan spaces

Best for: Bedroom or basement

#7 – hOmelabs Dehumidifier – 33dB

We like dehumidifiers that are compact, powerful for their size, and above all else – quiet. So why not end with one? 

The hOmeLabs Dehumidifier is no joke. It can take care of moisture in average size rooms of 1,000 sq ft. But it still manages to keep the noise down to a really impressive 33 dB. That’s ideal for spaces that need silent operation, such as bedrooms or small offices.

With an 8-pint-a-day capacity, this is a dehumidifier that can deal with standard-size rooms of 1,000 sq ft – removing moisture, improving comfort levels, and making a space healthier.

If you want to take the continuous drainage option instead of removing the water tank, note that this dehumidifier comes with a hose included. 

There’s also a user-friendly control panel that allows you to set your desired humidity level, before you let this baby loose and leave it to do its thing. 

Pros

• Very quiet (33 dB)
• Powerful
• Compact
• Excellent value

Cons

• Not suitable for large open-pan living areas

Best for: Quiet all-rounder for standard-sized rooms
