Dehumidifiers are essential for those living in stuffy, humid environments. If you’re tired of dealing with mold and mildew, getting a dehumidifier should be a top priority. However, some of them can be a bit too loud. You can use a quiet dehumidifier to cut back on the noise output without sacrificing its efficiency.

The best quiet dehumidifier is the TOSOT 20-Pint Dehumidifier because it quickly and quietly pulls moisture out of the air with an adjustable fan and an LED screen. Set timers, check the filter, and clean it by removing the back storage compartment. The base model works for 1,500 square foot rooms.

In this post, we’ll show you what to look for, along with a list of the best quiet dehumidifiers available.

What Should You Look For in a Quiet Dehumidifier?

Getting a dehumidifier helps you reduce the risk of mold paired with stagnant moisture in the air. While they’re always useful, nobody wants to deal with loud fans and vibrating motors. The good news is I’ve done the research to help you know what to look for when you’re on the hunt for a new dehumidifier.

Keep these three things in mind:

  1. Square footage: This factor is crucial because it determines how much space the dehumidifier can take care of. Multiply the length by the width of the room and get a dehumidifier that’s at least big enough to handle the size. I recommend going a bit higher if you live in a place with a lot of ambient humidity.
  2. Tank size: You want to make sure your dehumidifiers tank is big enough to hold a lot of water without having to be emptied several times per day. The goal is to only have to empty it once per day, if not a few times per week. If the tank is filling up too frequently, it’s a sign that the dehumidifier is too small for the area.
  3. Noise output: You’re likely here because you’re tired of dealing with loud dehumidifiers. Your unit should ideally be quieter than 60 dB to prevent it from being noticeably too noisy. All of the quiet dehumidifiers on our list below are under this threshold, so you’ll undoubtedly enjoy a noiseless setup.

Read on for in-depth information about each factor.

Square Footage

Your dehumidifier’s square footage rating is one of the most important specs. If it’s too small for the room, it won’t be able to hold enough water or pull it from the air. You’ll end up having to empty the tank too often. Furthermore, you won’t notice much of a difference in the relative humidity in the room.

On the other hand, getting a dehumidifier with high square footage won’t cause many issues. In fact, you’ll be able to empty the tank less often (provided there’s a large enough tank to handle the water in the air), and the motor won’t work nearly as hard. This process could indirectly make the dehumidifier a bit quieter.

Keep in mind that getting a larger dehumidifier typically means you have to spend more money. If you’re on a budget, you should aim for a dehumidifier that’s at least the room’s square footage. That being said, I recommend getting something that’s about 50 to 100 square feet bigger than you think you’ll need.

Note: If you decide to get a dehumidifier that’s far larger than the size you need, I highly suggest checking its decibel output. Many industrial size dehumidifiers come with extra-large fans and motors to pull more water out of the air. These components could make the unit significantly louder, ruining the purpose of looking for a quiet model.

Tank Size

While a dehumidifier’s square footage is important, it can often outperform its tank size. The tank size determines how much water the unit holds until you have to empty it. The vast majority of dehumidifiers come with sensors that stop the motor once the tank is full, meaning it won’t work if there’s too much water inside.

Using a hygrometer to determine the room’s relative humidity, follow this table to know what tank size you need:

Tank Size (Pints)Relative Humidity
45 Pints55%
45 Pints65%
50 Pints75%
60 Pints90%

(Source: Learn Metrics)

Getting the right tank size can make a world of difference. Much like the unit’s square footage capacity, you can’t go overboard with the tank size. A large tank means you have to empty it a lot less than usual, so it saves a lot of time and energy. A big water tank could be heavier, though (water weighs eight pounds per gallon).

Most dehumidifiers have removable tanks, but there’s a handful of them that use drainage hoses. You can get a long hose and drain the dehumidifier to a sink or tub without having to lug around a heavy tank. Many of them have removable tanks paired with hoses to let you choose your favorite method.

Noise Output

Some dehumidifiers are louder than house fans, making them a nuisance to operate. You shouldn’t have to choose between cleaning the air with obnoxious sounds or living in a stuffy, humid home. There are plenty of quiet dehumidifiers for rooms and vehicles of all sizes, the best of which we’ve covered today.

According to Bustle, quiet dehumidifiers are considered those that produce 50 decibels or less. For reference, that’s about the noise level of an air conditioner. There are many dehumidifiers that are quieter than 50 dB, especially those that are meant for small rooms, portable purposes, or vehicles.

Here’s a list of the noise output of all seven dehumidifiers on our list:

DehumidifierMax Noise Output (Decibels)
TOSOT Dehumidifier50 dB
Shinco Dehumidifier48 dB
Letsport Dehumidifier45 dB
Pro Breeze Dehumidifier30 dB
Seavon Dehumidifier30 dB
TECCPO Dehumidifier49 dB
Afloia Dehumidifier0 dB

Winners: Pro Breeze, Seavon, and Afloia Dehumidifiers

While these three dehumidifiers are the quietest on the list, they’re also the smallest. They can’t hold as much water as some of the other models, nor can they remove moisture from the air at the same speed. It’s up to you to decide if you prefer noise reduction or moisture reduction when comparing our favorite models below.

Our Favorite Quiet Dehumidifiers

Best Overall: TOSOT 20-Pint Dehumidifier

The TOSOT 20-Pint Dehumidifier is at the top of our list because it’s energy-efficient, easy to use, and relatively affordable. You can change various settings that range from 70 to 700 watts, letting you decide how much electricity you want to use. The higher the fan goes, the more watts it uses per hour.

On top of the TOSOT Dehumidifier, you’ll find an LED screen with several buttons. These options let you adjust the speed, timer, and power. There are multiple speeds to cycle through, and you can set a timer to run throughout the night. You don’t have to worry about morning humidity making it stuffy when you wake up anymore!

The filter setting on top of the dehumidifier lets you monitor when it’s time to remove and clean it. The filter removes fine particles from the air, purifying every breath you take. This dehumidifier includes a one-gallon tank and a ¾-inch hose. You can manually remove the tank to pour the water out or attach the hose and drain it elsewhere.

Bottom Line: The TOSOT Dehumidifier is an excellent model because it has everything you could ask for in a quiet dehumidifier without costing too much. From the removable filter to the Energy Star certification, you’re sure to get the most out of your new purifier.

Do you have a great room, large living room, or home theater you want to clean? Ambient moisture can lead to mold and other problems, which is why the Shinco Energy Star Dehumidifier should be at the top of your list. It’s ideal for large spaces, but you can also use it as a whole-house dehumidifier if you leave all of the bedroom and bathroom doors open.

The Shinco Dehumidifier takes it to the next level by letting you control the moisture level in the air with a button setup. You can also set a timer to run until the one-gallon tank is full. This unit includes several wheels, letting you move it around your house without a problem. There’s even a self-drying button to prevent mold and mildew from growing inside the filter.

The child-proof lock and auto-stop fan features make this great for families with children or pets. It also turns off if it tips over, preventing a fire hazard. Check the meter on top of the digital screen to know when the tank is full or if the filter needs to be cleaned. This model is easily one of the most advanced dehumidifiers on the market.

Bottom Line: This large room dehumidifier is quieter than many models half its size. It also packs a lot of power and prevents mold, mildew, and wood rot.

Best for Small Rooms: Letsport Compact Dehumidifier

Whether you want to dry a bathroom, bedroom, or a small living room, the Letsport Compact Dehumidifier is worth a chance. This compact unit isn’t too noisy and lets you place it anywhere with an outlet. It’s only 10 x 15 inches, so you can place it on nightstands, office desks, coffee tables, and more.

If you’re tired of dealing with complicated designs and remotes, you’ll enjoy this one. The only thing you have to worry about is a red power button that turns it on and off. Switching it on will keep your room below 35% relative humidity, which is more than enough to drastically reduce the chances of mold, mildew, and bacteria growth.

Leave the unit on as long as you want to because it automatically shuts off when the tank is full. There are three meters that indicate the power, how full the tank is, and whether it’s automatically running or manually operating. When the tank is full, turn off the power button and remove the tank with the safety tab.

Bottom Line: It’s hard to find anything close to the Letsport Compact Dehumidifier when it comes to quiet bedroom units.

Best Budget-Friendly Quiet Unit: Pro Breeze Electric Dehumidifier

The Pro Breeze Electric Dehumidifier is another compact design that’s very similar to the previous model. However, it’s significantly quieter at only 30 decibels. This model dehumidifier might not handle as much square footage as the Letsport dehumidifier, but it gets the job done for motorhomes, bathrooms, and small garages.

This model is proof that you don’t need to spend hundreds of dollars to get a decent dehumidifier. It’s also ultra-lightweight, so you shouldn’t have any problems leaving it in your kid’s bedroom or with a senior citizen. They’ll also enjoy the single-button control system that turns it on and off.

There’s a meter on top of the dehumidifier that shows how full the tank is. Once it’s topped off, you can pull out the tank with a tab, much like the Letsport model. This one has a plug that seals the water, preventing it from spilling everywhere. You can also use the plug area to remove the water with a siphoning hose or by dumping it.

Bottom Line: While it might not handle entire houses or apartments, the Pro Breeze Electric Dehumidifier serves its purpose. It’s tied with the quietest variants we’ve come across and makes everything as easy as possible from start to finish. Flip the switch to turn it on or off and keep an eye on the tank capacity meter.

Best Portable Design: Seavon Dehumidifier

Do you want to be able to take the dehumidifier with you wherever you go? The Seavon Dehumidifier has a long cable and only weighs a little over six pounds. The lightweight design lets you plug it into your car with an inverter or use it in bathrooms, bedrooms, motorhomes, and other places.

Although it’s a budget-friendly, compact dehumidifier, it comes with a few unique features. For example, you can cycle through seven colors to set the mood. The light is bright enough to act as a night light, but the matte transparent coating dulls the color to keep it calm.

Unlike most other low-cost dehumidifiers, this model has a removable, cleanable filter. Pull the tab on the back of the unit and run the filter underwater for a minute, dry it with a towel, then load it back into the dehumidifier. The tank is emptied with a tab, too.

Bottom Line: The Seavon Dehumidifier is surprisingly effective for such a budget-friendly dehumidifier. Its portability makes it a top-notch selection for almost anybody. You can keep one of these in each room to remove the humidity throughout the day and night.

Dehumidifier is perhaps the best all-around unit for big houses, warehouses, large garages, and so on. Set it in the center of the building and leave all of the bedroom and bathroom doors open for the best results.

Despite its incredibly high capacity, the TECCPO Dehumidifier only produces 49 decibels. It’s quieter than a whole-house air conditioner, but it comes with a filter that does close to the same thing. You can also hook it up to a drainage hose to remove the water while it’s running, preventing the tank from filling up.

If you don’t want to use the hose, the tank can be manually dumped. There are wheels that let you roll it around, too. Choose between several timers, a self-drying button to prevent mold and mildew, and an adjustable humidity range going from 30% to 80%. You might also enjoy the built-in handle for convenience and easy handling.

Bottom Line: This dehumidifier is big enough to prevent moisture buildup in most houses while putting all of the controls in your hands.

Best Quiet Dehumidifier for Cars: Afloia Mini Dehumidifier

If you want a small, quiet dehumidifier for your vehicle, gun safe, closet, or another small space, we suggest the Afloia Mini Dehumidifier. This model doesn’t require any electricity since it uses absorbent beads that soak up all of the moisture in the air.

Since there’s no motor in this dehumidifier, it doesn’t produce any noise. There aren’t any fans, either. You can set it on the dashboard, in the backseat, or in a glove compartment to slowly remove humidity throughout the day.

Bottom Line: The Afloia Mini Dehumidifier works slow and steady. It’s not going to clear a whole house or even a bedroom, but it’s the perfect solution in terms of portability, convenience, compact design, and reduced noise output.
