Dehumidifiers are a great investment for your home, not only because they reduce allergens such as dust mites, mold, and mildew, but also because they decrease your energy bills during those summer months by helping your air conditioner run more efficiently. The best quiet dehumidifiers, however, are devices which don’t draw attention to themselves functioning silently but still effectively. Especially for an upstairs bedroom or a kid’s room, you’re going to want the quietest dehumidifier you can find; the smaller the house or the apartment, the quieter the device should be.
The reason the quiet is so important is that dehumidifiers are typically devices which run for many hours in a row, often overnight, and that’s why the main focus of our review were the best devices with vast coverage areas and great dehumidification performances at a virtually silent level. Other features of our analysis included the models’ water tank capacity, inbuilt pump presence, and overall dimensions.
To compile this article, we’ve spent numerous hours analyzing tens of different models, their specs, the manufacturers’ websites, and hundreds of verified customers’ reviews. The products which made it onto this list are those which showed a consistent difference in each home by reducing power costs and quantity of dust, as well as improving the overall health of a family, all while running smoothly and quietly without issue. The following products are organized into a table with detailed reviews and a buying guide is included at the end to assist your shopping experience.
More features: continuous drain option; dry clothes function
This dehumidifier has a very modern and confined look which makes it less distracting and better-looking for those nicer spaces you’re trying to keep moisture and dust-free. It uses the compressor technology which can remove up to 30 pints of water per day from a humid environment up to 200 square feet. Built on wheels this unit is semi-portable, though best for ground floors, single rooms, or the basement area.
Its size offers a 45-ounce water tank. Additionally the unit comes with an intelligent auto shut-off function which ensures the safety of the system when water reaches a maximum level. Running noise is greatly reduced with a whisper-quiet design that will not disturb your work, relaxation, or deep sleep; total noise level is about 50 decibels, and even the full tank indicator is just a quiet function with a small light.
Button functions offer a 24-hour operation time, two-fan speed for a cool room with quicker moisture concentration, a dry-clothes function, and a three-minute automatic delay which will turn the compressor on and off every three minutes to save you power. You can also attach a drain hose so that the unit could run continuously without a need to empty the tank every now and again. Finally, there is an option which further ionizes the air for total purification of bacteria, odors, and other particles.
What makes it stand out?
Ideal for medium rooms; coverage area of up to 200 feet
Includes the most manual settings for your specific needs
Ionizing function for total air purification
Which disadvantages must you keep in mind?
The continuous draining pipe needs to be purchased separately
More features: low temperature operation; Energy Star certified
Depending on the size of the space you’re dehumidifying, this unit is available for purchase with a rate of 30, 50, or 70 pints a day; meaning tank sizes vary. All units use the standard 115-volt electrical outlet, though the larger they get the louder they are; for a standard 50-pint unit the noise level is 51 decibels (about the sound level of a quiet conversation).
The low-temperature-operation setting offers an energy saving solution throughout the day while you’re at work. Additionally the humidity range can be changed from 35% to 85% to eliminate more or less moisture in the air. Controls include a digital humidity readout, 24-hour on/off timer, and an indicator light for when the tank reaches maximum capacity. This device is Energy Star certified and includes a full one-year warranty.
Smaller units are more portable for room-to-room use or application in a single space like the baby’s room, whereas the largest unit is ideal for a whole floor or large bedroom, and even works as a small commercial dehumidifier. All components are easy to check and change out, including a full tank and the filter. With up to 50 liters for the medium dehumidifier, this is easily one of the best machines for moisture removal.

More features: handle at the back panel; energy-saving
One of the eco-friendliest options for your house, this portable dehumidifier is ideal for bathrooms, bedrooms, or other small rooms and studio-designed whole floors, while also running with a low energy cost that emits no harmful chemicals or uses them in processing the moisture from the air. Not only does this device remove mold and mildew by treating the saturated air, it has unique functions which dually purify your air while removing odors along with the water; an indicator turns yellow when maximum capacity is reached.
This unit has a 50-ounce tank size and can remove approximately 17 ounces a day from any given space, making it an excellent solution for your private office, small bedroom, or kids’ bedroom. Peltier technology allows this unit to run using an electric module mechanism rather than a compressor (pump), thereby making this unit extremely lightweight and portable, while also ensuring the unit is ultra-quiet wherever you’ve installed it.
The unit will remove dust, bacteria, fungus, prevent mold and mildew, while also ensuring your lungs are clear and your environment offers easy breathing. The product includes an indicator light for when the unit is on and for when the tank is full; with an automatic shut-off to avoid spillage.
What makes it special?
Includes an auto shut-off function when tank is full
Very portable option for a home
What cons did we find?
Leaks a little when the tank reaches full
Bin is not easy to remove when full
Needs emptying 2-3 times a day if running at full power
More features: continuous drain option; LED display controls; pump can remove water up to 15 feet away
For small to large houses, this floor unit offers a two-gallon tank with a dehumidification rate of 70 pints (nine gallons) a day for your whole home or even just the basement. Not only will this high dehumidification rate reduce the growth of mold and mildew, additionally it will make all your belongings dust resistant and your house practically hypoallergenic during those pollen filled summer months.
Approved for home and even commercial use in small stores with an Energy Star rating, this 70-pint dehumidifier considerably lowers energy bills and also makes it possible for your other electronic appliances to work correctly. Overall operation is virtually unnoticeable with a peak sound level of only 52 decibels (including noise added by the pump), which is comparable to a normal conversation. Designed with a Power Outage Restart setting which will reset the dehumidifier to its previous settings the moment power returns, this unit will also remove the hassle of constantly needing to reset the machine.
Other features include an easy-open ergonomic drain bucket, cleanable filter, and even the option of using a drain hose to remove the liquids. Setup is as simple as plugging your new device into the wall and activating your ideal setting, then sit back and watch the magic happen all day long for up to 4,500 square feet of your home.
More features: one-touch switch design, auto shut-off
Designed for a single room or office use, the Hysure T8P-US-G1 is compact and easily portable. The device is designed with Peltier technology which means it should be quieter than most other options in the market. This also explains the 33 dB max noise level. However, the Peltier technology is used in place of a compressor which is a popular design in most dehumidifiers. As such, there are no moving parts in the machine. Consequently, we noticed that while it is quieter, this option is not the most powerful and will likely not work for any room larger than 270 square feet.
Using the dehumidifier with the one-button included for operation seems quite intuitive. However, fluctuations in temperature and humidity can either increase or reduce the dehumidifier’s efficiency. At most, it can remove 26 oz of moisture in the room per day. This should help eliminate some allergens such as mold, dust mites, and more.
Also, the machine features a built-in 2000ml tank. Considering the coverage area and the working capacity of the device, we felt the tank fills up fairly fast. That said, the machine can detect when the tank is full and activate the auto-shutoff feature. Additionally, the indicator light will also be activated so you can empty the tank.
Lastly, this dehumidifier is very economical with its electricity consumption.
What do we love it for?
Ideal for medium rooms with a maximum size of about 270 square feet
Features auto-shutoff as well as an indicator to empty the tank
Compact and portable
What were we disappointed with?
The tank will need to be emptied often
Won’t work for larger spaces
Things to Consider
The remainder of our guide is designed to explain certain features of dehumidifiers and why they are important; frequently asked questions are answered at the end.
How to prolong your dehumidifier’s life
Taking care of your dehumidifier with the simplest steps can significantly extend its life and usefulness, for instance, your tank should be changed out at least daily or immediately when full to avoid moisture damage and internal mildew. Settings can also prolong your machine’s life by lowering the power it takes to run the dehumidifier all day or lowering the amount of moisture the machine has to process at all times; machines with 24-hour timers are ideal for highly humid environments. In fact, for these environments, it’s suggested you give your dehumidifier a full day’s break at least once a week.
Additionally, check and clean or replace the filter at least once monthly, make sure you’re using the right outlet for higher power needs, and turn off the dehumidifier in bathrooms and kitchens while taking a shower or bath or doing the dishes.
Features to consider while choosing a quiet dehumidifier
Many of the following features are listed with the products above, in this section, we further elaborate on each feature and why it’s essential to a dehumidifier’s operation, additionally to assist your buying experience we have included examples of machines which are ideal for certain features.
It is an essential feature to keep in mind if you’re looking for a dehumidifier for a bedroom, living room or a nursery. Customers’ main problem with cheaply made dehumidifiers are their noisiness, and it’s because a machine’s constant whirring cannot only quickly become annoying, but also keep you from getting work done or even getting any sleep.
The number one most important feature, therefore, is the noise level a dehumidifier puts out, and that’s why our list only reviewed the products which had been verified by customers to be extremely quiet and non-irritating. The best of these are the smaller more portable dehumidifiers such as the Hysure T8P-US-G1, Eva-Dry EDV-1100, and the Vacplus 30 Pints Dehumidifier .
Almost of equal importance is the dehumidification rate which refers to the amount of moisture which is removed during an hour or an entire day. While smaller machines may be quieter, it’s typically the medium to large devices which have the best rates of dehumidification, though some of these are both quiet and can remove a massive amount of liquid from the air, such as the Tosot 70 Pint Dehumidifier with Internal Pump. This machine can remove up to 70 pints a day. However the ideal amount of moisture removal often depends on your needs and so only you will know which dehumidifier will work best for your space.
The Vacplus 30 Pints Dehumidifier has a coverage area of around 200 feet which is your standard basement area or ground floor including kitchen, dining, and living room spaces. For a confined space, however, something more energy-efficient and small might be better, like the Hysure T8P-US-G1; now although this has a similar coverage area, putting in a confined space will actually show more results and a higher rate of moisture removal every hour. Then clearly for large coverage areas, you’re going to want something a bit bigger and more powerful, though typically you only need this for very large houses, office spaces, and the like, such as the Tosot 70 Pint Dehumidifier with Internal Pump.
Dehumidifiers with pumps are simply more efficient at removing moisture from the air quickly and in higher quantities. A pump will make it necessary to use a dumping hose for constant water removal while the machine is running, either that or you’ll need to empty a tank throughout your day. The good news is that a pump allows you to not only use the continuous drainage but also direct the hose out of a window or into a sink, situated above the unit. One of the best options on our list with an extraordinarily quiet pump is the Tosot 70 Pint Dehumidifier with Internal Pump.
Water tank capacity
Depending on where you live, your moisture situation, and the area you need the dehumidifier for, your ideal water tank capacity will change. For instance, in a small space like a confined kitchen or bathroom you’d want a machine with a medium water tank capacity such as the Frigidaire 50-Pint Dehumidifier, this is because the environment is already naturally moist with extra water entering the air from your tap when running a shower, cooking, or doing the dishes.
In drier confined environments like bedrooms you typically only need a small unit with a tank capacity of around 30 ounces and lower; though apparently if you live in a highly humid area, your needs will be different than those living in the cold, dry mountain areas.
Dimensions and weight
If you’re planning on moving your dehumidifier around throughout the day or throughout a week from room to room in your house, consider options with wheels or which are just naturally light; the Hysure T8P-US-G1 and Eva-Dry EDV-1100 are both very compact and easy to move around (once emptied). Otherwise, large non-portable dehumidifiers can be very hard to transport around your house, and typically you should only buy these if you’re confining them to a particular area of your home.
For a warranty, you want a period which gives you long enough to receive and test your product. Around six months to a year will provide you with long enough to ensure that the product came without any defects and that it operates as promised by the seller.
Some features which we consider especially useful and well worth the investment include: automatic shut-off feature for when the tank reaches full, timers which control how long your unit runs during the day or night, LCD warning lights for a full tank, no-spill tanks, power saving options such as low temperature operation, and finally units which list a room’s humidity levels throughout a day. Two of the best machines with similar functions are the Vacplus 30 Pints Dehumidifier and the Frigidaire 50-Pint Dehumidifier. One-button dehumidifiers are good at turning on and removing water, but for the most part, their functions are somewhat limited and can’t be set with specifications that fit your needs.
Typically, eco-friendly dehumidifiers – ones which are guaranteed not to use chemicals to purify the air – are the best options for your nursery; this is especially true when the unit is designed to run quietly and not reach full tank capacity while your child is sleeping. Larger models are typically too loud for a nursery, too big for the space, and they use chemicals to remove moisture or as a lubricant to keep a pump running correctly.
At around 24 hours of operation most dehumidifiers will put off a little heat either from the machine body or the plug, this is perfectly natural and it’s suggested you then let the machine rest for an hour or double check that you haven’t left the dehumidifier running with a full tank. However, typically a low heat is okay, and you can leave the machine running.
Models with pumps are a bit louder than those without, however, such dehumidifiers are guaranteed to be more efficient at removing large quantities of moisture in less time than non-pump machines. Also, they allow you to pump water in any direction, not only down, but even horizontally and vertically up to 15 feet. Typically, machines with pumps are also much larger.
For the top products on this list, you don’t need to look any farther, based on customer reviews and our own research these three products are easily the best quiet dehumidifiers on the market.
Vacplus 30 Pints Dehumidifier. This machine has one of the best performance functions with the most water removed from the air in the shortest time. Additionally it has a medium tank capacity and great extra functions for a particular space.
Frigidaire 50-Pint Dehumidifier is our second pick. With the highest range of functions for your home, this machine has a setting for all your needs: it even has a specific feature for drying your clothes wrinkle-free. It can be left running at a higher power to remove more moisture, or even set to a Low Temperature option which can be left on while your away or sleeping and reduce the amount of energy the unit uses.
Hysure T8P-US-G1 is our Budget Pick for this list. This is not just an affordable home product, it’s also convenient for removing moisture from single rooms like a nursery.
