When levels of humidity are too low or too high, it can make things uncomfortable both day and night. But where is comfort more essential than in a bedroom where you are sleeping all night? When choosing a reliable dehumidifier for your bedroom, the most important factors to consider are the size and humidity levels in your room, as well as noise generated.
Dehumidifiers are commonly used during the summer when humidity is at the highest, but you can use it any time if you live in a humid region. It can be hard to find the right balance of temperature and humidity for maximum comfort throughout the night. Take it from me – I lived a big portion of my life in southern Florida where weather is very tropical. Although dehumidifiers can be really effective against high humidity, many of them are too loud to use in a bedroom, and can actually disrupt your sleep if they turn on and off at night.
You don’t have to suffer when there are quiet dehumidifiers you can use in your bedroom. If you need help choosing the right unit for your bedroom, check out this guide I’ve put together based on my own research.
If noise is the most important factor for you, and you aren’t focused specifically on a dehumidifier sized for a bedroom, you may also want to check out our picks for the overall most quiet dehumidifiers.
Consider my top six picks below to find the best dehumidifier for your bedroom.

Top Picks for the Best Dehumidifier for a Bedroom
Frigidaire 22-pint Dehumidifier
Frigidaire is a well-known brand of high quality home appliances. My favorite thing about Frigidaire dehumidifiers is the sleek and modern look and excellent build quality. This small 22-pint unit is powerful yet quiet enough for most bedrooms with high humidity problems. Additionally, Frigidaire is Energy Star rated to help save money on your bills.
Select your desired humidity level from 35% to 85% and set a timer to start or stop operation after 0.5 to 24 hours. Unlike most other brands, Frigidaire has three fan speeds: Low, Med, and High. Choose the lowest setting for minimal noise during bedtime.
Compared to other 20-pint or 22-pint models, Frigidaire’s 9-pint water bucket is fairly large. The unit also has the standard auto shut-off feature as well as a bucket full indicator. The front loading bucket with handle and splash guard make manual draining convenient for you. Alternatively, you may connect a standard garden hose to the drain port on the back of the unit to enable continuous drainage.
Although it’s more compact than the higher capacity 35-pint and 50-pint Frigidaire units, this 22-pint dehumidifier is on the bulkier side, on account of its large water bucket. You may notice that Frigidaire dehumidifiers don’t have a Defrost indicator light. This is because they work continuously in temperatures as low as 41°F without an Auto Defrost mode that turns off the unit periodically to melt ice. One downside is that Frigidaire comes with the standard one-year warranty. With its high end quality, Frigidaire is also at the high end in terms of cost.
PROS
• Energy Star certified
• Effortless humidity control
• Quick and efficient moisture removal
• Low temperature operation
• High tank capacity
• Continuous draining option
CONS
• 1-year warranty
hOmeLabs 22-pint Dehumidifier
Although hOmeLabs came to the market only quite recently, its dehumidifiers have made a good name for the brand. This particular unit is rated to remove up to 22 pints of excess moisture in spaces from 500 to 1,500 square feet. This Energy Star certified dehumidifier ensures high performance without sacrificing your electricity bills.
Like most dehumidifiers, hOmeLabs makes a noise you cannot avoid, but a lot of users report that it’s more of a pleasant fan sound that serves as white noise to help you sleep. On the control panel, you can select a target humidity level from 35% to 90% and set the timer to delay start or stop for 0.5 to 24 hours. Comfort mode automatically sets the humidity level and fan speed based on the ambient temperature, while Continuous enables nonstop dehumidification.
This 22-pint dehumidifier has a 0.8 gallon water tank with auto shutoff and full tank alert. For continuous drainage, attach a standard garden hose (not included) to the drain port. Built with four wheels and two side handles, the unit can be easily dragged anywhere you need a quick moisture removal. It operates in temperatures as low as 41°F and the auto defrost feature shuts off the unit when frost forms.
Compared to other 20-pint or 22-pint dehumidifiers, this unit is lighter and smaller. On the downside, the thin and lightweight plastic feels cheap and less durable. However, the good value of hOmeLabs far outweighs any drawback. The unit also comes with a longer two-year warranty.
PROS
• Energy Star certified
• Efficient moisture removal
• Custom humidity control
• Continuous draining option
• Budget price
• 2-year warranty
CONS
• Low quality design
Waykar PD160B
Waykar offers a variety of dehumidifiers for many different needs. One of these is this model which removes a maximum of 34 pints of moisture from the air in areas up to 2,000 square feet. (Although in some stores this unit is called a 40-pint dehumidifier.) This unit is commonly used in a small basement, laundry room, bathroom, living room and even a bedroom due to its low noise levels.
Set the humidity from 30% to 80% and the unit will cycle on and off to maintain your desired level. If you set the humidity to 30%, the unit will operate in Continuous mode. The Timer allows you to delay start or delay stop between one and 24 hours. The digital display will show the current humidity, selected fan speed, remaining time, and the indicator lights.
This portable dehumidifier has a small 0.66 gallon/2.5 L water tank with automatic shutoff and a “Full” indicator light. But, if you want your dehumidifier to run continuously, simply attach the included 6.56 ft drain hose to enable automatic draining.
Like any refrigerant dehumidifier, Waykar operates in temperatures between 41°F and 95°F (5°C and 35°C). In low temperatures, the unit goes in auto defrost mode to prevent frost buildup that may damage the machine. Additionally, this unit comes with an easily accessible and washable filter for a better air quality. It has an extendable top handle and four smooth-gliding wheels for easy movement. The air outlet on top can be adjusted to dry your laundry quicker. It’s a great dehumidifier overall, but on the downside, this Waykar unit isn’t the most energy efficient you can find at this size.
PROS
• Light and portable
• Quiet operation
• Continuous drainage with hose included
CONS
• Small tank
• Low energy efficiency
Ivation 19-Pint Desiccant Dehumidifier
Unlike my other picks above, this Ivation dehumidifier uses desiccant technology for an effective and quiet operation in temperatures as low as 33°F to as high as 104°F. It can remove 19 pints of moisture per day in any space up to 410 square feet.
This portable dehumidifier is very quiet since it doesn’t use a compressor. The only part that makes noise is the fan. The top display shows the current humidity and temperature as well as your selected fan speed. You can adjust the humidity level from 35% to 85% or run the unit continuously. The auto stop function prevents damage by automatically shutting off the unit during threat of tilt or water overflow. Its additional safety features makes this Ivation desiccant dehumidifier perfect for RVs and boats, but it’s also great for any small space such as a bedroom, bathroom, or laundry room.
This smart dehumidifier features Sleep mode with low fan speed and dim screen for your comfort. Set the timer to turn on or turn off the unit between 1 and 12 hours. You can also change the fan speed and adjust movement of the air vent to help dry your clothes.
It comes with a washable air filter and a 0.75-gallon tank with a transparent water level window and a built-in handle. You may connect the included hose for continuous drainage. If you need a powerful and quiet dehumidifier you can use in a small bedroom and anywhere inside or outside the house, the Ivation 19-pint desiccant unit is a good choice. Although, be aware that desiccant models typically cost more and consume more power.
PROS
• Quiet desiccant operation
• Works in a wide range of temperatures
• Continuous draining option
• Small and portable
CONS
• Higher costs
Seavon 35oz Dehumidifier
For small bedrooms, it may be more ideal to get a smaller and cheaper Peltier dehumidifier like this Seavon unit. This tiny dehumidifier removes up to 16 oz (450ml) per day and holds 35 oz (1000ml) in its water tank. It is recommended for rooms within 2600 cubic feet or 285 square feet. Its whisper quiet operation is possible through the use of the Peltier effect or thermoelectric cooling.
This Seavon dehumidifier has two working modes: high speed and low speed which operates at 30 to 39 decibels. It also features a seven-color LED light. Along with the exhaust, it has two buttons on top, one for the power and the other to control the fan speed and light. The light changes color by default, but you can also choose one color or turn it off completely. The unit is equipped with the standard auto shutoff which stops operation automatically and the red light will flash when the tank is nearly full.
Since this is a “large” Peltier dehumidifier, there’s a recessed handle on the back of the unit for portability and a removable and washable filter to catch dust and keep the air clean. One downside is Peltier dehumidifiers are designed to work at temperatures from 59-86°F. This unit will not work below 41°F.
PROS
• Small, lightweight, and portable
• Low energy consumption
• Whisper quiet operation
• User-friendly controls
• With 7-color night light
CONS
• Small capacity and coverage
• Very limited operating temperature range
Pro Breeze Mid-Size Dehumidifier
Since we’re talking about Peltier dehumidifiers, we can’t not include Pro Breeze. This mid-size Peltier dehumidifier extracts up to 18 oz (500 ml) of excess moisture per day. Its 52 oz (1500 ml) water tank . This means you only have to empty it at least every two days. It is perfect for any space up to 2200 cubic feet or 250 square feet. For even smaller spaces, consider this more compact Pro-Breeze unit.
This mini dehumidifier is incredibly easy to operate with just a single button for the power switch. One push and it will start dehumidifying, another and it will stop. It also has the auto shut-off functionality as well as a “FULL” indicator light for when the water tank is nearly full. To drain, simply remove the tank on the front of the dehumidifier, pull the plug out, then pour the water into the sink or drain.
Peltier dehumidifiers are nearly soundless since the only moving part is the fan, making them ideal for bedrooms. This lightweight and portable Pro Breeze unit can easily be placed on a countertop, table, or shelf. Similar to other thermoelectric dehumidifiers, it operates best at temperatures from 59-86°F.
PROS
• Small, lightweight, and portable
• Low energy consumption
• Whisper quiet operation
• Easy to use
CONS
• Small capacity and coverage
• Very limited operating temperature range
Choosing the Right Size of Dehumidifier
Check the Humidity Level in your Bedroom
To find the right size dehumidifier for you, the first thing you have to do is to determine the humidity levels in your bedroom. Note that the ideal indoor humidity is around 40% to 50% RH. If the humidity rarely goes past 60%, then you’ll likely need a smaller capacity. Meanwhile, if humidity levels are usually around 80% to 90%, then you will need the maximum capacity recommended for your room size.
If you don’t have a hygrometer to measure the exact values of relative humidity in the room, watch out for the common signs of excess moisture. Damp and musty air is a common sign of humidity. You may also notice condensation on windows and walls or damp spots on your floor. In extreme cases, you’ll see mold growing on wall corners, beneath carpeting, or almost any moist surface. The more severe the dampness, the higher capacity dehumidifier you’ll need.
Measure the Size of your Bedroom
Another important factor to note is the size of your bedroom. You want to get a dehumidifier that can actually make a difference to the entire room. Multiply the length and width of your bedroom to get the area in square feet or square meters. Alternatively, multiply the length, width, and height to get the volume in cubic feet or cubic meters. Manufacturers usually indicate either one or both, so it’s best if you know the two when choosing a dehumidifier.
Bedroom Dehumidifier Buying Guide
Aside from the size, the following factors must also be considered to find the best dehumidifier for your bedroom.
Type of Dehumidifier
There are different types of dehumidifiers depending on the method of dehumidification they use. The most common is the compressor type which can be loud yet very effective in warm and humid conditions. Mini dehumidifiers use Peltier technology for whisper quiet operation in small spaces. For low temperatures, a desiccant dehumidifier is the most efficient and quiet option.
Drainage
Since you’ll be using the dehumidifier in your bedroom, a drain or sink may not be as accessible as it would be in a bathroom or basement. You don’t want to carry a full water tank to a far distance and risk spilling on the way. Before you buy a dehumidifier, make sure you can work out a hassle- and mess-free way of draining the collected moisture. If possible, make use of the continuous draining option in a large capacity dehumidifier. Place your dehumidifier near the ensuite bathroom if you have one to make draining much more convenient.
Noise Output
Noise can be subjective, and it can also vary depending on other environmental factors. The most quiet dehumidifiers produce an average of 40 to 45 decibels, and 35 to 40 decibels for Peltier dehumidifiers. Average dehumidifiers produce anywhere from 53 to 70 decibels. For your reference, whispers are around 30 decibels, rainfall is at 40 decibels, and normal conversation goes from 50 to 60 decibels. Most users find it easier to fall asleep with 30 to 40 decibels white noise.
Energy Efficiency
An average compressor dehumidifier draws at least 200 Watts for a small 20-pint or 22-pint, while Peltier units can go as low as 20 Watts. A desiccant typically consumes about twice the power consumption of a similar sized compressor dehumidifier. Look for the Energy Star label to make sure you’re getting an energy efficient dehumidifier. You can find the energy efficiency information in the manual, on the unit itself, or in the Energy Star website.
Portability
To save on costs, look for a quiet dehumidifier that you can use in the bedroom at night, as well as other parts of the house during the day. For easy movement, you want a unit as small and compact as you can get yet powerful enough for each of your rooms. Larger dehumidifiers are built with wheels and handles for portability. But if the humidity in your bedroom isn’t that high, a mini dehumidifier may be all you need.
Other Useful Features
Your bedroom dehumidifier should include standard features like auto shut-off and auto restart. For bigger units, a built-in humidistat is a must. You’ll also find it useful to have light indicators for when the tank is full or when you need to wash the filter. Different fan speeds and operation modes give you greater control on the humidity and the amount of power your dehumidifier consumes.
Other Ways to Reduce Humidity in your Bedroom
If you’re not ready to purchase a dehumidifier just yet, there are some ways that can help reduce humidity in your bedroom naturally.
The most obvious way is to open all windows and doors to let fresh air in. Use fans to improve air circulation, but only when you’re in the room. Different types of fans are good in different conditions.
If you don’t want to open the windows in fear of letting in bugs or other unwelcome visitors, turn on your air conditioner. It’s not the most effective or economical solution, but it does help lower humidity as it cools down the air inside the room.
If you have a bathroom attached to your bedroom, take shorter, cooler showers as much as you can. This is a common cause of excess humidity and it can spread to your bedroom. Additionally, if you have wet laundry inside, it also adds moisture to the air. Turn on an exhaust fan during or after your shower to eliminate the humid air. If the humidity is too high, then you might need a bathroom dehumidifier too. When you do get a bedroom dehumidifier, you can also use it in your bathroom during the day.
