Best Quiet Dehumidifiers of 2021 – Complete Buyer’s Guide

| Last Updated: September 12, 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

You won’t find a better unit for the money, with the Afloia Electric Air Dehumidifier earning a top 5-star rating. Yet this unit’s upside doesn’t stop with affordability. It also has great coverage compared to similarly-sized units and the longest warranty on the list. And topping it all off is a weight of 2.38 pounds, making it the most portable unit, as well as the quietest.

Bottom Line

Combining portability with quiet operation and affordability is no easy task, but the Afloia does it in style. The sleek exterior and numerous color options also allow you to match it with your existing decor, even if it’s in the bedroom or living room. Even with a 2-star cost-efficiency rating based on its ability to remove moisture, it’s a winner in terms of price and nearly noiseless operation.

Pros

Sleek design

Four color options

Automatic shutoff to prevent overflow

One-button, one-touch design for easy use

Small size is ideal for all types of common-use rooms and even RVs

Cons

Poor efficiency in temperatures over 90 degrees

May not work as well in excessively moist or wet areas

Review

Though it comes with a hefty price tag, the Waykar dehumidifier is a great option for exceptional water removal compared to its size, garnering a 5-star cost-efficiency rating. The source of its power is four air outlets, which can absorb water more quickly than the single-vent choices that are found among other quiet units. A child lock also provides additional security if you have little ones running around, and the anti-frost protection prevents you from inadvertently damaging or ruining the unit from running it for too long.

Bottom Line

Although the Waykar has superb water removal from the air and extraordinarily quiet operation for its size, a massive price tag compared to others gives it a 0-star affordability rating. But if you want a quiet unit that will cover tons of square footage and more control than a basic unit, this is a sound choice.

Pros

Covers up to 4,500 sq. ft.

Anti-frost and freeze protection

Child lock settings to prevent accidents

Four air outlets for faster dehumidification

Intelligent touch-control panel for easy operation

Cons

Doesn’t pull as much water out as smaller-pint units

Fan doesn’t have much power even in high setting

Review

If you want a sleek, small unit that fits just about anywhere, the Afloia T8PLUS should do the trick. Thanks to electric operation instead of using a coil, it’s whisper-quiet while also offering a decent amount of moisture removal, hence the 3.5-star cost-efficiency rating. An indicator light lets you know when to empty the water tray, which also has an easy-empty feature so you aren’t spilling water on the floor.

Bottom Line

While the unit is small, it doesn’t offer nearly as much dehumidifying power as similarly sized units, earning it just a 1-star space efficiency rating. Yet despite this one downside, quiet operation, a 3-star affordability ranking, and its ability to blend into your decor make this a decent unit for the money.

Pros

Easy-empty water tray

Lightweight, sleek design

Full water tank indicator light

Built without a coil to reduce noise

Small size allows it to fit anywhere

Cons

Covers only 269 sq. ft.

Poor option for larger rooms

Review

For a no-frills mini dehumidifier, few other options can beat the Tenergy dehumidifier. Simply plug it in, turn it on, and you’re ready to go. Although it doesn’t get as much water out of the air as other options, hence its 2-star space efficiency rating, its lightweight design earns it a 3.5-star portability rating.

Bottom Line

While this unit gets a 0-star cost-efficiency rating for its low-end water removal, it’s perfect for bathrooms, closets, and other small spaces. And weighing in at just 2.5 pounds, anyone can move it with ease.

Pros

Plug-and-play operation

Built-in automatic shutoff

Ideal for small spaces and areas

Review

A 30-pint unit would rarely compete in the quietness department with other dehumidifiers that have about 2% of the dehumidifying capacity, but that’s just what the Shinco SDL offers. It also earns a 4.5-star cost-efficiency ranking — a testament to Shinco’s ability to remove water from the air for a fraction of the cost of other units. And as far as a 30-point option goes, this unit also provides great space efficiency, allowing you to tuck it away in almost any area without worrying about running into it or taking up precious space.

Bottom Line

Though the Shinco dehumidifier gets top marks for cost efficiency, space efficiency, and quiet operation, it’s somewhat hindered by its bulky 21 pounds, giving it just a 0.5-star rating compared to other quiet dehumidifiers. But with its solid dehumidifying action and wheels and handles to offset the weight, this unit can still compete with the other options on the list.

Pros

Programmable timer

Covers 1,500 sq. ft.

Easy-control LED panel

Wheels and handles for easy moving

Drains automatically and continuously

Cons

Expensive compared to other options1

Included drainage hose is absurdly short

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

The best quiet dehumidifiers keep the moisture out and your bedroom dry while allowing you to get some rest. They won’t emit an annoying buzzing noise throughout the night that could interrupt your sleep or wake up your resting infant.

Exam Room

Many institutions use a quiet dehumidifier in their exam rooms to allow their students to take their tests in a comfortable, silent space. Using the quietest dehumidifier available can effectively control the humidity level of an exam room without throwing a student’s concentration.

Daycare 

Daycares need to invest in a quiet dehumidifier to control the humidity level of their sleeping areas. It allows the children to sleep in comfort and without the threat of a buzzing noise disrupting their rest.

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. 

Movability

Waykar 34-Pint Dehumidifier

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. 

Auto-restart

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

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

Ivation GDM30

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.

Conclusion

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. 

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.
