Best Quiet Dehumidifiers of 2021 – Complete Buyer’s Guide

| Last Updated: May 21, 2021

We rarely think about the content in the air we breathe. Other than the main gases (nitrogen, oxygen, and carbon dioxide), air also contains water vapor, which is referred to as humidity. These moisture levels are defined as a percentage called relative humidity.

Relative humidity is affected by various factors including altitude, season, weather condition, and human activity (for example hanging wet clothes indoors, cooking, and constantly having damp material in the house). Sometimes, the extra humidity could come from rising damp. It sometimes seeps up from the ground, through the walls.

Excess moisture acts as a culture spot for mildew, dust mites, and mold. These have been linked to life threatening diseases. Excess humidity also causes rust on metal surfaces, and can have adverse effects on your electronics. Investing in an efficient dehumidifier prevents some of these problems.

A dehumidifier is a device that reduces the amount of water vapor in the air. It works by taking in large amounts of air, removing the moisture in it, and blowing the now-dry air back out. Extracted moisture collects in a drip tray which you have to empty every once in a while. The best levels of humidity for comfort are 40% to 60%.

Are These Dehumidifiers Actually Quiet?

The straightforward answer is yes. Most dehumidifiers on this list fall below the 60 dB line, which is akin to a normal conversation between two people. One of the options on our list is virtually noiseless, only emitting sound during the renewing process. In the comparative noise matrix, breathing is measured as 10 dB, while a hair drier is 70 dB.

Manufacturers reduce noise by using highly efficient compressors and cutting down available fan speed settings. Exhausts are strategically placed at the top to reduce the noise levels. Multiple filters and moving parts are also sources of noise, so having fewer parts makes your dehumidifier considerably quieter.

How to Choose a Quiet Dehumidifier

There are a few things you need to be on the lookout for when buying a quiet dehumidifier. These include:

The Noise Level

Since you’re looking for a quiet dehumidifier, this is the most important factor. The lower the decibels it measures, the better the choice. This will – however – impact other factors such as price. Quieter dehumidifiers tend to cost more.

Energy Efficiency

This is important, since you will be adding on to your electricity bill if you choose an inefficient dehumidifier. Be on the lookout for the ENERGY STAR sticker, which shows you the unit has been tested and rated for energy efficiency.

Space Covered

Knowing where you will use the dehumidifier will help. If your home has large rooms for instance, you will have to be on the lookout for the 1500 to 4500 square feet range. Also, a living room dehumidifier can be louder than a bedroom one – the TV will mask noise.

Ease of Use

Look for the dehumidifier with the easiest control panel. It should also have an easy to view LED screen, and multiple smart options to help you plan around your usage.

Having an auto resume feature (in case of a power outage) is an added advantage.

Review of the Best Quiet Dehumidifiers

Even with a clear list of must-have features, you still have hundreds of brands to choose from. Here’s a slightly narrower list. We’re sure you’ll find a dehumidifier here that works for you, but even if you don’t, this is a good foundation for your search.

hOmeLabs 1,500 Sq. Ft Energy Star Dehumidifier for Medium to Large Rooms and Basements


  • Energy efficient
  • Easy to use controls
  • Has wheels for portability
  • Quiet fan even when in operation
  • Sleek, modern design with good build quality


  • Has a small tank
  • Does not come with a hose for draining.

As the name suggests, the hOmeLabs 1,500 Sq. Ft. Dehumidifier is created to work in large rooms of up to 1,500 square feet. Even as the smallest dehumidifier in the hOmelabs, it’s ideal for large rooms, basements, storage spaces, and even small warehouses. The dehumidifier is capable of removing up to 4 gallons of moisture daily.

The fan has different settings, which can take it from normal (129 cubic feet) to turbo (138 cubic feet of air) per minute. It comes in a sleek, well put together design that looks like a computer desktop tower in some ways. The company offers a 2 year warranty on the unit, with an additional 6 months if you register on their website.

There are wheels on the unit, so it can be moved to a different location if needed. Using this unit is also very easy. You set your ideal humidity levels, and let the unit run continuously. If you don’t adjust the settings, it will continue to run all day, or until the tank fills up, after which it will automatically shut down.

The tank is easy to remove and empty, and you can drain it down a common household sink. There’s a drain outlet for a hose, although the hose does not come with the product at purchase. A common 5/8 inch garden hose with an internally threaded end is ideal. You can also add Teflon tape to secure it properly.

Bottom Line

For sheer functionality, the hOmeLabs 1,500 Sq. Ft. Dehumidifier takes the cake. It’s also capable of removing odors and allergens such as pollen from the air. This is definitely the unit to get.

Frigidaire Energy Star 50 Pints-Per-Day Wi-Fi Controls, Large Dehumidifier for Home, Basement, and More, FGAC5044W1, White


  • Continuous operation
  • Quiet fan in operation
  • Easy to use controls with digital readout
  • Compact durable design with portability
  • Energy efficient unit (ENERGY STAR CERTIFIED)


  • The humidity sensor is incorrectly placed and this affects reading accuracy

This beautifully designed machine is ideal for large rooms, basements, offices, and storage spaces, up to 2,500 square feet. It operates at a relatively low temperature of 41ºF. It’s capable of working with a large humidity range (35 to 85%). It’s ENERGY STAR rated for energy efficiency, so its effect on your power bill will be minimal.

The Frigidaire 50-Pint Dehumidifier is quiet at a noise level of 51 dB. This is about the same amount of noise an electrical transformer makes when it’s 100 feet away, so the dehumidifier is ideal for your living area or office space. It can be moved thanks to the caster wheels at the bottom, and the handles at the top and sides.

The filter that eliminates odors and allergens is removable, for easy cleaning. The controls are electric and easy to use. They are paired with a digital readout, making it easier to set your ideal humidity levels. The dehumidifier is capable of working continuously, or until the tank is full at which point it will auto-shut.

If a hose is attached to drain away water from the tank, this unit will work uninterrupted. There’s a full tank alert that lets you know when it’s time to empty the reservoir. The tank is located at the front of the unit, to make it easy to remove. It comes with a carrying handle and a splash guard to reduce chances of accidental spills.

Bottom Line

The quiet operation and the energy efficiency are big advantages to owning the Frigidaire 50-Pint Dehumidifier. They could have added an outlet hose with the product at purchase, but this is otherwise an excellent choice.

Honeywell TP70WK 70 Pint Energy Star Dehumidifier for Basement & Large Room Up to 4000 Sq Ft. with Anti-Spill Design, White, 50


  • Portable
  • Easy-to-access washable filter
  • Auto-restart in case of power outage
  • Smart humidifier with digital controls
  • Energy efficient in operation (ENERGY STAR certified)


  • No automatic defrost
  • Noticeable noise levels for an allegedly quiet dehumidifier

This is one of the more powerful options when it comes to dehumidifiers and space. Capable of cleaning up to 9 gallons of air every day, it’s rated at a 4,000 square foot capacity. It’s very well made and backed by a 5 year limited warranty. The Honeywell DH70W 70 pint Energy Star Dehumidifier comes with two fan settings; high and low.

The operating temperature is a cool 41ºF, which means its power consumption won’t hurt your bill. It’s also ENERGY STAR certified for efficiency. Maintenance is also relatively easy, since there are few removable parts. The air filter reduces dust and allergens. You can wash it under your kitchen sink faucet. There’s no need to replace it.

The water tank holds up to 14.4 pints, is detachable, and is easy to clean. It also has comfortable handles and an anti-spill feature that makes it easy to carry. The cleaning process for the tank is also easy, with the rest of the unit requiring a simple wipe down.

The controls are digital and paired with a large easy to read LED display. This indicates the current temperature, humidity settings. It’s also where you program the 24h timer.

Bottom Line

The Honeywell’s large capacity and the washable filter are what make it perfect for basement usage. Since basements are – for the most part – large, dusty, humid spaces, you need a dehumidifier that requires minimal attention and can run non-stop. You don’t want to keep going to the basement to check on your device.

Smallest Quiet Dehumidifier:
New and Improved Eva-dry E-333 Dehumidifier

Eva-Dry Wireless Mini Dehumidifier, White (E-333)


  • Small and compact design
  • 100% renewable and non-toxic
  • Renewable silica gel technology
  • Very quiet unit when in operation
  • Does not use any batteries or electricity


  • Covers a small area of operation
  • Takes some time to dissipate the moisture it collects

This is one of the smallest dehumidifier units in the market. It’s also among the lowest price points. Although it has no batteries, it doesn’t require constant connection to electricity. This is because unlike other dehumidifiers in this list, the New and Improved Eva-dry E-333 Renewable Mini doesn’t use fans. Instead, it uses a silica gel to remove moisture from the air. As a result of this technology, the unit is virtually noiseless.

The small amount of noise it does make blends with ambient noise, including the hum of the fridge. It’s capable of removing 6 ounces of moisture before reaching full capacity. This makes it perfect for bathrooms, closets, gun safes, and small storage spaces for paper. Once it’s full, you then plug it into an outlet for the moisture to dissipate and the unit to recharge. This is called “renewing”.

The indicator has silica crystals that change color from orange when dry to green when they’ve absorbed enough moisture. This typically takes 3-4 weeks. Since it has no water tanks and no filters, this unit adsorbs water vapor from the air. Once it has been captured, the water can’t spill or leak.  The unit can be used for up to 10 years.

This unit is extremely easy to use. Since it doesn’t use power or batteries, you don’t need a control panel. You only need to know when the silica needs renewing. This simplicity also makes the maintenance of this product very easy. There are no parts to remove or replace. The product is also non-toxic, which makes it great in a house with children.

Bottom Line

Built for small spaces, this is a dehumidifier that will serve you diligently for years to come. It’s also 100% renewable.

Bottom Line

Danby Energy Star 30-Pint Dehumidifier


  • Small portable design
  • Full tank indicator light
  • Reasonably well priced
  • Automatic de-icer for the coils
  • Operates at low temperatures of up to 41ºF


  • Noticeable noise levels for a small dehumidifier

In some cases, it’s been known to work in spaces of up to 1,700 square feet, but factors such as humidity and temperature will definitely affect it.

The Danby Energy Star 30-Pint Dehumidifier has a smart function. It controls the humidity in the room by factoring in ambient temperature. It’s also energy efficient with an ENERGY STAR rating, meaning it’s kinder to the environment and good for your bills as well. It operates on two fan speeds, high and low. It’s relatively quiet on the low setting, although noise levels increase to a noticeable hum when set to high.

Although it’s pretty light at 30 pounds, this sleek machine has been put together using quality material and the highest craftsmanship. It comes with an auto-resume feature.

Maintenance is relatively easy, thanks to its removable filter and the direct drain system. The multi-directional caster wheels, coupled with the easy to grip handle, make moving this unit from room to room a breeze. It also has a humidity sensor that can be set in 5% increments, between 35% and 85%. It automatically shuts off when the room reaches your chosen humidity setting.

Bottom Line

What makes it ideal for the bedroom is its relative silence. It’s more than capable of handling your excess humidity needs at low noise levels that let you sleep peacefully.

Emerson Quiet Kool 50-Pint Dehumidifier with Built-in Vertical Pump, White


  • Filter is easy to remove and clean
  • 3 fan speeds for more maneuverability
  • Digital control panel with large LED display
  • Auto-resume feature in case of a power outage
  • Large working humidity range of between 35% and 80%


  • There’s a noticeable drop in power after about 9 months to a year of use

This is one of the best options for large spaces. It’s capable of removing up to 9 gallons of moisture from the air every 24 hours, spanning over 4,500 square feet of space. All the water is put into a large 13.65 pint reservoir that’s removable and has an easy-to-monitor water window, which shows the level of liquid collected.

The design is sleek and the Emerson Quiet Kool EAD70EP1 70-Pint Dehumidifier looks like a really stylish suitcase from some angles. It’s also very well built. The warranty is tiered, to make it easier for both you and the manufacturer. There is a 1 year warranty for labor, 2 years for the rest of the parts, and 5 years for the compressor.

This unit has a drainage pump included at purchase. The pump makes removing the water convenient by pumping it above (and away from) the device, to a run off point of your choosing. It’s different from gravity draining, where a hose is connected to the unit and drains water to a runoff below (but away from) the humidifier. This option is also available on the Emerson EAD70EP1.

The drainage pump comes with a hose, but you will have to put in a garden hose if you prefer the gravity option. You also get 3 preset smart options, namely: continuous, bedroom, and basement. These take into account the different challenges in each scenario, adjusting your fan speeds accordingly. They use highly efficient motors and compressors to reduce the amount of noise produced during operation.

A digital control panel with an LED display lets you easily calibrate the machine to your needs. It’s portable, thanks to its 4 caster wheels, which can move in multiple directions. The Emerson Quiet Kool EAD70EP1 70-Pint Dehumidifier has auto-resume. In case of a power outage, it starts the unit back up and operates on its previous settings.

Bottom Line

A large area of operation, quiet fans, and an auto restart feature all make this a worthwhile purchase. The drainage pump and the secondary drainage option are also a great addition. It’s made from fire resistant material that has been given the highest flammability standard, UL60335.

Electric Dehumidifier, iSiLER Portable Dehumidifier with 2L(4.2 Pints) Water Tank, Electric Mini Dehumidifier for Bathroom, Auto Shutoff Ultra Quiet Dehumidifier for Basement, Kitchen, Bedroom, Closet


  • Small portable design
  • Very quiet when in operation
  • Large working temperature range
  • Easy to read moisture and tank indicators
  • 3 months unconditional return and replacement policy


  • It only dehumidifies a small area

At 8.9×5.9×14.7 inches, this is a tiny dehumidifier that fits anywhere inconspicuously. This makes it ideal for bathrooms, kitchens, and even bedrooms. In a workplace setting, this works well in individual offices, stock rooms, and conference areas. It has a 2 liter detachable water tank and is capable of removing about 750 ml of water from the air daily. It works best at temperatures of 86ºF, and between 40% and 80% humidity.

This low temperature of operation coupled with its small size, mean that the dehumidifier uses very little power; about 65 watts. That’s only a little more than a normal house lightbulb. It’s well made with a durable build quality. There’s an unconditional return and replacement policy that kicks in at purchase.

However, the warranty on this dehumidifier is only for 12 months. The ISILER Electric Dehumidifier is easy to use, thanks to its one button operation, coupled with an auto-off. Simply press the ‘on’ button. The indicator is green when the unit is operational. It will run continuously, and when the indicator turns yellow, the tank is almost full, and the unit will automatically shut off.

This is one of the quieter dehumidifying options in the market today, at only 40 dB when in operation. This makes it the ideal gadget for use in bedrooms, study areas, and even children’s rooms. The unobtrusive design will look at home on any countertop, whether it’s a low-fuss reading room or a conservative office space.

Bottom Line

For a small unit, this is a very functional dehumidifier. The low operating noise level is endearing, especially in the bedroom. The tank is also large enough to work for two and a half days before you need to empty it.

When Would a Quiet Dehumidifier Come in Handy?

There are many places a quiet device would be desired. Here are a few examples:

Bedroom Setup

Quiet Dehumidifier vs Regular One - Are They Really That Different?

How much of a difference does it make to find a dehumidifier that operates more quietly? 

Similarities of Quiet and Regular Dehumidifiers

Energy Efficiency

Both types of devices have an energy-efficient dehumidifier available to help lower your electric bill.

Ease of Use

Most dehumidifiers are easy to install and set up without professional or technical support. The different controls are also easy to use. 


Regular commercial dehumidifiers are equipped with caster wheels, while the quiet ones are lightweight and easy to move around. 

Compact Design

Both types of dehumidifiers are compact and don’t take up too much space, making them convenient to use in a small room or office. 


Both types of dehumidifiers have brands that auto-restart in case of power outages. It’s a convenient feature that keeps the machines going even if you’re not around to manually restart them. 

Washable Filter

Both devices allow you to remove and clean the air filter after it’s accumulated dirt and grime.

Differences Between Quiet and Regular Dehumidifiers

Noise Emission

The clearest and most significant difference is that quiet dehumidifiers don’t emit any noise, regardless of their fan speed. Both devices have fans, but only a quiet dehumidifier will spare you from that irritating buzzing.

Perks of Having a Quiet Dehumidifier

Whether it’s for your home, office, basement, or even smaller spaces like closets and gun safes, owning a dehumidifier has its benefits. These include:

  • Maintaining habitable humidity levels, which make rooms more comfortable to be in. Lowered humidity also means the atmosphere is less hospitable to bacteria, mildew, and mold-causing spores.

  • They have filters which remove bacteria and odors from the air. They also remove allergens such as dust and pollen.

  • They work quietly and unobtrusively, meaning your routines and habits will not be interrupted.

  • They help lower the energy costs in your home. As a unit, a quiet dehumidifier doesn’t use a lot of power. They however help the AC function more efficiently. They remove moisture from the air, which is half the work. Your AC repair and replacement costs also go down.

  • Quiet dehumidifiers help extend the life of your upholstery, drapes and wall paper. All these suffer when there’s too much humidity. They can fade, discolor, or even start to rot.

How Do I Maintain My Dehumidifier So That It Stays Quiet?

A quiet dehumidifier can last for some time if it’s taken care of. Here are steps and tips for caring for your quiet dehumidifier:

1. Follow the Manual 

Most manufacturers detail how to use the dehumidifier properly, which helps with its durability. 

2. Install it Correctly

The best place to install a dehumidifier is where there are no obstructions or open windows and doors. Ensure it lies on an even surface that allows proper air circulation.

Additionally, make sure your room isn’t too cold or you can damage the dehumidifier over time. 

3. Clean the Air Filter

Make sure to clean and pour out the excess moisture of your dehumidifier's air filter. It’s an essential part of this machine as it clarifies the air of dust and other harmful particles. You can also replace your worn-out air filter. 

4. Keep the Water Reservoir Clean

Empty and clean the water reservoir frequently. Use soap and water to remove all the accumulated slime and dirt at the bottom.


Investing in a quiet dehumidifier is the perfect balance between functionality and peace. You get all the benefits of having a dehumidifier, with the main exception of the obvious noise. They also come with a bunch of smart options to pre-program various functionalities. All this is done at a tiny cost to your electricity bill, and in some cases, none at all. 

Quick Recap: Best Quiet Dehumidifiers

People Also Ask

Below are some frequently asked questions:

What Can Be Done to Quiet a Dehumidifier?

Placing your dehumidifier on a soft surface to absorb the sound and putting it as far away from common areas will reduce the annoyance caused by the motor running.  

What are the Decibels for a Very Quiet Dehumidifier?

Quiet dehumidifiers have a dB level below 60, while a very quiet dehumidifier has around 20db. 

Do Pumps on Dehumidifiers Make More Noise?

Condensate pumps in quiet dehumidifiers don’t make any noise. These dehumidifiers are more expensive but worth it if silence is necessary. 

Are Quiet Dehumidifiers Worth It?

Yes. They ensure spaces that require total silence remain noise-free. They’re effective whether you’re trying to rest or you want your baby to sleep.

How Do I Figure Out if it is Energy Efficient or Not?

The best way to know whether the dehumidifier is energy efficient is to look for an ENERGY STAR rating. This is usually prominently displayed on the packaging, and on the unit as a sticker. The product description will also have power consumption information, which you can compare with other electronic appliances. As a last (or first?) resort, check the internet for the energy efficiency ratings of your chosen model.

Can One Quiet Dehumidifier Work For Multiple Rooms?

It depends on two main factors; total square footage and air conditions. If the combined area of your rooms is less than the square footage covered by the dehumidifier (and if the rooms are connected via vents), then it should work.

That said, performance will be influenced by air conditions, especially humidity and temperature. You should also make sure there are openings in the rooms for better air flow. Still, manufacturers recommend one dehumidifier per room. You could always buy a portable one and just move it around as needed.
