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 10 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 That Make a Good Quiet Dehumidifier
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.
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.
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 (2021)
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 10 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. Frigidaire 70-Pint White Dehumidifier
If you’ve been researching quiet dehumidifiers, you’ve probably already read reviews of the Frigidaire unit. The particular model I’ve linked to can extract up to 70 pints of moisture from the air per day. However, the company also makes a 50 and 30-pint versions of the device.
The largest version is 24.4 inches tall, 15 inches wide, and 11.6 inches deep. However, despite its size, it’s not going to be hard to move around, thanks to the four swivel wheels at the bottom. It also has a conveniently retractable handle that comes up from the top panel.
The rest of the model has a fairly simple and understated design. The exterior is mostly white, except for the transparent ring-shaped cutout in the tank drawer that lets you see the water level, and the top panel, which is gray. The grilles that suck in and expel the air are in the back, so the front has a very clean appearance.
Additionally, the top panel has a humidity meter display in the middle and various controls and light indicators on the sides. There are timer and fan speed settings on the left side, and water tank and filter indicators on the right. Finally, the power button is the rightmost setting.
The 70-pint version of the product can also come with a connector hose, a drinking water hose, or a lead-in hose. Setting your dehumidifier near a drain and hooking it up to a hose would allow you to use it continuously. And if you choose to use it that way, you’ll be pleased to learn that this product is Energy Star certified. It will even keep working in low temperatures.
2. hOmeLabs 70-Pint 4,500 Sq. Ft 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 52 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.
While the previous two products are some of the quietest ones on the market, according to user reviews — this one has numbers to support the claim. According to Tosot, their dehumidifiers can make up to 48 decibels of noise.
4. Danby Energy Star 70-Pint Dehumidifier
Danby dehumidifiers are also some of the quietest ones on the market. In fact, their 70-pint unit is particularly well-regarded for that reason. The company also makes dehumidifiers for smaller and even larger areas, such as their 30, 50, and 95-pint units. However, since those devices have slightly different designs, I’ll focus this review on the 70-pint one.
The device has swivel wheels and hand grips on both sides, with air grilles just under them. So the fans won’t be facing the room, which should help direct any noise elsewhere. Like the other products I’ve mentioned, this unit is Energy Star certified. It even has an automatic defrost function, which means that it can work even in temperatures as low as 41 degrees Fahrenheit.
The unassuming white box is 24.2 inches tall, 16.1 inches wide and 11.8 inches deep. There’s a water tank drawer in the front, though users also have the option of using the direct drain system for continuous operation. If you don’t hook the device up to a hose, it’ll stop working when the tank is full.
As always, all the controls and light indicators are on the top side of the box. When the filter indicator light comes on, you can just take the filter out and wash it.
5. Emerson Quiet Kool 70-Pint Dehumidifier
Emerson Quiet Kool devices take silent operation seriously — that much is evident from the company name. In fact, all of their dehumidifiers use efficient compressors and motors to minimize noise. This particular model comes with 30, 50, and 70-pint capacities. Moreover, all of those units can come with or without Wi-Fi connectivity.
At just over 25 inches tall, 15 inches wide, and 12 inches deep, this product should be fairly unobtrusive in your home. The case is white with some gray accents — such as the handles on the sides and the grille on top, which is the one that releases dry air. Conversely, the machine draws the air in through the filter in the back, which is fully removable and washable.
The controls and the light indicators are all on the top side of the device, where you can set the humidity and the fan speed, among other things. Unlike most of the other dehumidifiers we’ve seen, this one actually comes with 3 preset modes for continuous use, for the bedroom, and the basement.
These models have a removable water tank drawer and can operate fairly silently. However, you may hear some extra noise from the internal draining pump, which is an optional feature on the 70-pint units. Still, even then it should run pretty quietly — and if you’re worried, you can just pick a unit that doesn’t have one.
6. Keystone 50-Pint Portable Dehumidifier for 3000 Sq. Ft.
The 50-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 6.4 pints 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 11 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 36-pound appliance around. Even the 70-pint version of the device is only slightly larger — and the noise levels are about the same too.
7. Afloia Portable Quiet Dehumidifier for Home 68 oz Water Tank
Now, these last four 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 Afloia dehumidifier works best in areas up to 269 square feet. The product can actually absorb 26 ounces of moisture per day in 86-degree Fahrenheit heat and 80% relative humidity all while keeping noise levels below 42 decibels.
The unit itself is fairly small, at almost 16 inches tall. 9 inches wide, and 6 inches deep. It’s also completely black, except for the fully transparent 4.25-pint water tank drawer in the back.
Furthermore, unlike the simple, box-shaped units we’ve seen, this one has quite a nice shape to it, with rounded edges and a pleasant slope toward the top of the unit. There’s a long handle on the side of the device with the water drawer, which will allow you to easily pick up the 5.69-pound unit.
There are two intake grilles on each side of the device and a larger outlet grille all along the front side. The top panel has a single button, allowing you to turn the machine on and off — but not much else. The unit doesn’t seem to have a hose outlet, but it will automatically shut down if the tank fills up. Maintenance will be a breeze thanks to the removable and washable filter.
8. Hysure Dehumidifier,700ml Compact Deshumidificador 1200 Cubic Feet
The Hysure dehumidifier looks like the smaller cousin of the product we just discussed. At only 10.5 inches tall, 6.4 inches wide, and 4.2 inches deep, this little thing will blend right into its surroundings — especially because it comes in both white and black. It’s also about half the weight of the previous product, at 2.71 pounds.
Like the previous product, this one has one-button control. The button glows green when it’s working and yellow when you need to empty the water drawer in the back. Since the machine can pull up to 10 ounces of moisture from the air per day, and the tank can hold about 23.66 ounces, you’ll only need to empty it every two or three days.
Much like the other products on this list, this one has automatic shutoff features. And best of all, the amount of noise it makes is well below 33 decibels. So in this case, smaller is better!
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.
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.
