A few months ago, I helped one of my friends get rid of mold that had begun to take hold of his exterior walls. He had black patches in the corners of his bedroom and little black specks all over the walls. But even after we got rid of the mold, the damp smell still saturated the room and all the furniture in it. Knowing that a simple dehumidifier would solve most of his problems, I started looking for the best quiet dehumidifiers for bedrooms.
In the end, I discovered about ten quiet dehumidifiers that would be perfect for rooms of different sizes. As you’ll see, some brands keep repeating — and I’ve even reviewed some of their products before. So they definitely had the noise levels of their products in mind when they were designing them. As always, I’ll present my reviews after a brief list of features you’ll want to look for when shopping for your silent dehumidifier.

Why You Need a Quiet Dehumidifier for Your Bedroom
There is one major flaw most regular dehumidifiers have: the faint buzzing or whooshing noise they make. It’s a necessary part of these kinds of devices since they use rotating electric fans to draw the humid air inside and push it back out. Therefore, the amount of noise a dehumidifier makes really depends on the design of the fans and the acoustic quality of their housing.
Still, a regular, noisy dehumidifier might be acceptable for your living room, where any noise would be drowned out by the sound of the TV. However, you should probably aim higher if you need one for your bedroom. But how do you know if you need a dehumidifier, anyway? Well, there are a few telltale signs:
- You’ve noticed wet patches on your walls or ceilings
- There are dark spots on the walls — those are indicators of mold or mildew
- There’s a musty scent in the room
- You often find condensation on the windows
- The ventilation is poor or nonexistent (usually the case in smaller, windowless bathrooms)
If you make it a habit to close the windows in your bedroom before going to bed in order to prevent noise from coming in, you may want to get a dehumidifier. After all, even breathing increases the amount of moisture that’s floating around in the air. So if you tend to sleep with the door and windows shut, you’ll rest easier with a quiet dehumidifier. In fact, it might be as good as an air purifier if you want to be rid of pollutants.
Features to Consider When Shopping for Quiet Dehumidifiers
Even within the general product category of dehumidifiers, there are different specifications and features. How do you know which ones are important and which ones aren’t?
Let’s talk about it. Here are some features you need to look out for when choosing a quiet dehumidifier.
Low Noise Levels
The first thing I mention in all of my product buying guides are the noise levels you ought to expect from the products I’m reviewing. The best way to compare the amount of noise a particular product makes is if the manufacturer included the decibel measurements in the product description. However, since that doesn’t happen often, I end up looking at user reviews and YouTube videos to make sure that the products on my list pass muster.
By and large, dehumidifiers are about as noisy as a fridge — though many are even quieter than that. The ones that have exhaust fans on top tend to be slightly louder than the ones that have the fans on the side, though. In my opinion, that’s probably because having the fans on the side allows you to aim the sound away, whereas having it pointing up disperses it into the room.
Still, with some luck, your dehumidifier should only make about 50 decibels of noise, which is as quiet as a gentle rain. Some of the more compact models generate as little as 30 decibels or sometimes even less.
Space Capacity
Machines that help improve the air quality of your home usually have a certain limit. Air conditioning units can’t really be as efficient in an enormous room as they would be in a smaller one. So dehumidifiers, just like space heaters, have a certain space capacity.
The space capacity of a dehumidifier is usually included in the product description as a square footage number indicating the maximum surface of the room the unit can cover. Usually, that number’s anywhere between 1,500 and 4,500 square feet, if you’re looking at the larger dehumidifiers. Smaller ones work in the 150–300 square foot range.
On the other hand, some products measure that in cubic feet, for the volume of air the device is able to process.
Efficiency
The efficiency of a dehumidifier depends on the size of the device you’re using. And I don’t just mean that a small one isn’t efficient enough to draw out the moisture in a large space.
Most products on the market tell you how much water they can collect in a single day. For example, while the smaller ones can get 9 ounces of water per day or a pint in two days, larger ones could do up to 70 pints in that time. However, that’s not the only number that measures efficiency.
In addition to that, you also need to look at wattage. Since bigger dehumidifiers usually have more wattage, they are often faster and much more energy-efficient than smaller ones. Still, both kinds of devices have made my list, since you may not need much more than a small model if you live in a small apartment — or you plan to only use it in your bedroom. If you’re worried about energy efficiency, you can always stick to the products that have Energy Star certifications.
Ease of Use
Most dehumidifiers aren’t simple on-off devices. They usually have extra features, like humidity level meters, full tank indicators, and timer controls. Most of them also have fan speed settings — as always, slower speeds are going to be less audible. More advanced units have other features as well, such as the ability to restart in the event of a power outage.
However, certain things are the same pretty much across the board. Since these devices draw moisture from thin air, they actually have water tanks inside them. As the tank fills with water, the float in it presses the switch that turns the fans off and turns on a light indicator.
So you’ll have to periodically empty them in order for them to keep working efficiently. Additionally, you’ll need to clean or replace the filters inside your dehumidifier as well as its external shell. The inside of these machines is usually damp, which ironically creates the perfect conditions for bacterial growth.
10 Best Quiet Dehumidifiers on the Market
When I was choosing the products I wanted to review today, I made sure to include units that would be compatible with various space sizes. The following ten items are listed in order of descending size, which should correspond with their space capacity.
So if you need your dehumidifier to handle a large and humid space, you’ll want to use one of the 70-pint units. Otherwise, get one of the smaller products down the list.
1. AIRGJOB 70-Pint Quiet Dehumidifier for Large Capacity Room
This AIRGJOB model has a 70-pint capacity (a 50-pint option is also available), meaning that it can adjust the humidity level in your home to anywhere between 35% to 80%. It is 24.3 inches tall, 15 inches wide, and 11 inches deep. With these dimensions and capacity, it is suitable for any space of up to 4,500 square feet.
What sets this humidifier apart from most other models on the market is its smart-stop feature. Namely, the unit stops for 8 minutes every 8 hours, which allows it to cool down and reset. Due to this feature, the dehumidifier has improved durability and can work continuously without overheating.
Speaking of continuous running — you can connect the machine to your water supply via a hose. Thus, it is perfect for rooms that are constantly humid and need a dehumidifier 24/7.
Next, the humidifier also comes with a highly sensitive dual sensor. It reports any dips in humidity and temperature in the room and adjusts the humidifier’s settings accordingly. And if you’re worried about water dripping all over your floor as the humidifier runs, there’s great news. This model has a water float design that prevents spillage even if you run it on the turbo speed setting.
Lastly, this unit never exceeds 58 decibels of noise. As such, it is a good fit for large bedrooms, living rooms, and any other spaces you use for relaxation or sleeping.
2. hOmeLabs 70-Pint Energy Star Dehumidifier for Extra Large Rooms
The next unit on my list is a 70-pint dehumidifier from hOmeLabs, a company you may already be familiar with. After all, many of their products have already ended up on my lists of quiet household appliance recommendations. They make one of the quietest ice makers on the market and they already have experience making quiet air treatment products — like air purifiers.
Like the previous product, this one comes in 30, 50, and 70-pint per day capacities. So they’re capable of working in 1,500, 3,000, and 4,500 square feet areas, respectively. If you have a smaller home, you don’t need to get the most powerful of these units.
Basically, since these devices use the refrigeration method to dehumidify the air, the resulting air is a bit hotter than the one that goes into them. So the room needs to be large enough for the heat to dissipate.
The 70 and 50-pint units are 24.3 inches tall, 15.4 inches wide, and 11 inches deep, while the smallest one is just under 20 inches tall. It’s white, like the first product in my reviews, and it has a water tank drawer in the front with a small transparent window. These dehumidifiers also have swivel wheels to make them easy to cart around.
Once again, all the controls and light indicators are on top of the device, where you can adjust the fan speed, timer, and humidity. The filter grille and the hose outlet are in the back. If you want to use this unit continuously, you can — after all, it is Energy Star certified. However, you’ll have to get a 5/8-inch hose separately.
3. TOSOT 70-Pint Dehumidifier with Pump for Large Rooms
The TOSOT dehumidifiers suck in the air through the grille on the front side of the device and push it out through the one on top. However, even though the fans are right in the front, they make only 50 decibels of noise even at the highest speed setting. Once again, this dehumidifier comes in 3 versions, each capable of extracting 30, 50, and 70 pints of water from the air in a day. Like the other products I’ve mentioned, this one is Energy Star certified.
The largest unit is 24 inches tall, 14.8 inches wide, and 11.4 inches deep, so slightly smaller than the other we’ve seen. However, it still has a 1.6-gallon water tank as well as the internal pump you can use if you want continuous drainage. The smaller versions have a gravity drain hose connection instead. Still, the 70-gallon unit with the internal pump also comes with a 15-feet long hose.
Notably, the 50-pound device doesn’t have swivel wheels, so you’ll have to figure out another way to move it. The controls are once again on top of the box, with the power button on the left, followed by a filter indicator, a humidity digital display, a fan speed button, and a timer.
Furthermore, this model also has a power outage restart feature, which means that you won’t have to reset your preferences if the power goes out.
4. BRITSOU 50-Pint Quiet Dehumidifier for Medium to Large Room With Drain Hose
This model made by BRITSOU has a 50-pint capacity and is fit for spaces of up to 3,500 square feet. However, the manufacturer also offers you a larger option that can extract up to 80 pints and is fit for even bigger and more humid rooms.
Depending on your needs, you can pick between three dehumidifier modes. The DEHU mode will keep the humidity levels in your room at a healthy level as long as the machine is on. Next, the DRY mode is suitable when you need to dry laundry or treat an area affected by water damage. And finally, the CONT mode is ideal for extremely moist places that need around-the-clock dehumidification.
The unit comes with a 0.66-gallon tank and a smart water indicator that lets you know as soon as you need to drain it. In the meantime, the machine will turn off to prevent overheating and spilling. And if you need continuous drainage, you can use the 3.28-foot hose included in the package to connect the dehumidifier to your water supply.
As far as noise is concerned, this unit is one of the quietest you can come across. It never goes beyond 40 decibels, making it a perfect choice for medium-sized bedrooms and offices.
Lastly, this model’s design is quite sleek and compact. It has an ergonomic top handle for easier maneuvering, as well as swiveling wheels. As such, it is effortless to move despite its 32-pound weight.
5. KEYSTONE Energy Star 35 Pint Dehumidifier
The 35-pint dehumidifier from KEYSTONE may not have the cleanest design, but it’s still one of the most popular products on the market. The machine features air grilles in the back and front of the case, which may not be the easiest to clean. Still, it’s so efficient and quiet that no one seems to mind. In fact, this unit only makes up to 55 dBA, so noise shouldn’t be much of an issue.
At least the filter in the back is removable and washable. You’ll also be able to remove the water tank in the front. The water bucket is smaller than we’re used to at this point, with a capacity to hold only 6 liters of water. However, this dehumidifier is capable of continuous draining, as long as you get a good hose to hook it up to.
As always, all of the controls are on top, including the humidity meter, the timer, the fan speeds, and the power button. There are also several modes you can use, including normal, turbo, and auto-defrost.
At 23.2 inches tall, 15.4 inches wide, and almost 10.8 inches deep, the unit is fairly easy to maneuver. It even has rolling coasters on the bottom, which will allow you to easily move the 38-pound appliance around. Even the 50-pint version of the device is only slightly larger — and the noise levels are about the same too.
6. Gocheer Upgraded Dehumidifier for Home 68 OZ
Now, these last five units on my list are going to be your best bet if you don’t expect the device to treat the air in your whole house. This Gocheer dehumidifier works best in areas up to 800 square feet. It is only 13.2 inches tall, 8.2 inches wide, and 5.9 inches deep.
This dehumidifier can remove up to 2 pints of water in one go, after which you will have to drain it. However, its smaller size and capacity have one big advantage — the unit never goes over 30 decibels of noise.
Designed with your safety in mind, the dehumidifier shuts off as soon as its tank fills. A water level indicator will light up immediately, alerting you that it’s drainage time. Thus, you don’t have to worry about the water overflowing or the machine overheating if you have to step out of the house.
If you opt for this unit, the manufacturer offers you a 30-day money-back guarantee, as well as a 3-year warranty. The customer service team is quite helpful and responsive, so you can shoot them a message with any questions and concerns.
Finally, it’s worth mentioning that this dehumidifier uses up only 1.15 kilowatt hours of electricity per day. In other words, it is one of the most eco-friendly and cost-effective options you can go for on the market.
7. TABYIK Small Quiet Dehumidifier for Home and Bedroom 35 OZ
This TABYIK model is another great option if you need a small dehumidifier for a space of up to 280 square feet. It is only 10.1 inches tall, 5.9 inches wide, and 5.9 inches deep. Due to its size, it consumes only a single kilowatt-hour per day.
The dehumidifier comes with a light button that lets you choose between 7 colors, so it can also serve as a lamp for your room. Plus, the light and dehumidifier are separate, so you can also turn on one without using the other if that’s what you want.
Although it comes with only a single working mode, it is an extra quiet sleep option that never exceeds 28 decibels. Therefore, the unit won’t disturb your sleep even if you place it right by your bed.
This model also features an auto-shut-off feature, and it kicks in when the tank is about 70% full. At that point, the unit will turn off and you will have to drain the tank before running it again.
Since it weighs only 16 ounces, you can move the machine around your home or take it with you on trips. It has a sturdy built-in handle on the back, so carrying it’s effortless.
8. AYAFATO Small Dehumidifier for Home, Bedroom, and Bathroom
If you’re looking for a sleek black dehumidifier, this offering by AYAFATO will check all your boxes. Its dimensions are 9.8 by 7 by 6.3 inches, and it is suitable for rooms of up to 280 square feet.
Consuming less than 1 kilowatt hour per day, the device can collect up to 1 pint of moisture before it needs draining. This capacity makes it an ideal option for bedrooms, offices, and bathrooms.
Besides the fact that it is extra quiet (less than 26 decibels), this dehumidifier also emits white noise. In other words, not only will it not disturb your rest, but it can actually help you sleep better.
Like some of the other models discussed, this one also has a night light feature. You can turn it on with a press of a button and pick between 7 different colors. Your choices include blue, purple, red, orange, yellow, green, and cyan.
Due to its compact size, this dehumidifier is fit for travel. So, you can use it in your RV or take it with you on vacation. That way, you can ensure the air you breathe is healthy and safe no matter where you are.
9. hOmeLabs Small Space Dehumidifier with Auto Shut-Off
The second hOmeLabs dehumidifier on my list is a far cry from the first one I reviewed. It’s even smaller than the previous product I described, at only 8.5 inches tall, 6.5 inches wide, and 5.3 inches deep. Still, even at that size, it would be ideal for small bedrooms and bathrooms. However, it wouldn’t be much help in rooms that are over 150 square feet.
The machine has grilles in the front and on the sides, and the removable filter on top. There’s a simple power switch in the front with two light indicators next to it — one to tell you if it’s on, and the other to remind you to empty the tank.
Speaking of which, the transparent drawer can only hold about a pint of water. However, it can only extract about half a pint or 9 ounces per day. So you’ll only be emptying it once every two days.
10. Eva-Dry E-333 Renewable Mini Dehumidifier
The Eva-Dry device is certainly the tiniest one on any list of quiet dehumidifiers. However, the 9 by 8-inch device doesn’t need a cord or batteries to work.
Instead, the unit uses renewable silica gel to wick the moisture from up to 333 cubic feet of air. In a regular room with 8-foot tall ceilings, that should translate to about 40 square feet.
The reason why the manufacturer calls this dehumidifier renewable is simple. The silica gel crystals inside it are orange while they can absorb the moisture. After a few weeks, they turn green.
At that point, you’ll just need to move the device to a ventilated area and plug it in for about 10 hours. Then, the crystals will be ready to be used again — and they’ll even last you about 10 years!
Benefits of Having a Dehumidifier (Silent or Not)
So what can a dehumidifier do to improve your living conditions, aside from getting rid of the smell of mold? On the most practical level, it removes moisture from the air.
Once the air is inside the device, different models have different methods of drawing out the moisture. In refrigeration dehumidifiers, the air passes through pipes that hold a freezing cold coolant. These pipes extract the moisture from the air, which then drips harmlessly into a collecting tray below. Before the air goes back out, it passes through warm pipes to get back to room temperature.
Other kinds of dehumidifiers work slightly differently. For example, some might extract the moisture not by cooling the air but by using absorbent materials. But why do we need to make sure that the humidity in our homes never goes over the ideal 40–50%? In other words, what are the benefits of having a dehumidifier?
Well, for one, dehumidifiers can actually hinder mold and mildew growth on your walls, not only get rid of the odors they create. Furthermore, they also protect your clothes, furniture, and curtains from the mold. Dehumidifiers also improve the overall air quality in your home, so you’ll see less dust. And that decreases the chances that you’ll get dust mites.
If you usually dry your laundry indoors, it’ll dry faster with the aid of a dehumidifier. And, if you happen to set one in your kitchen, you’ll notice that your bread will remain fresh for longer. A dehumidifier would also make your AC more efficient since it wouldn’t have to dry the air before cooling it.
More importantly, dehumidifiers are great for people with respiratory conditions. Moist environments are the perfect breeding grounds for pollutants and allergens, so dry air is simply easier on the lungs.
Final Thoughts
If you’re looking to reduce the humidity levels in your home, you can’t go wrong with one of these devices. Whether you decide to use them in your room, around the house, or in the basement — you can be sure that you won’t hear a peep out of them.
Now all you need to do is figure out the square footage of the space you’ll use them in. Then, it’s all about the kinds of features you want to have. Ultimately, any one of them will allow you to breathe more easily in your own home.
