How Loud is a Dehumidifier?
If you've ever been looking for a dehumidifier for sale, you may have been curious about how noisy these appliances are and how they can affect your quality of life. Ultimately, nobody wants a device that increases interior noise, particularly in areas where quietness is prized, like offices or homes.
For that reason we’ve created this blog to go over everything you need to know about dehumidifiers and their noise levels so you can make the best choice when purchasing one.
What Is a Dehumidifier and How Does it Work?
Before we get into the reasons and factors behind the noise levels of LGR dehumidifiers, let’s first look at the basics. Dehumidifiers are home appliances that are meant to remove excess moisture from the air in order to lower and maintain the optimal levels of humidity that are found inside a building. A high humidity level can result in a number of issues, such as the growth of mold and mildew, the presence of dust mites, and musty aromas, all of which can have an adverse effect on your health and comfort. By successfully managing the amount of moisture in the air, dehumidifiers contribute to the creation of a living environment that is both healthier and more comfortable.
The way a dehumidifier works is straightforward yet efficient. Through the use of a fan, it sucks in humid air, which is then allowed to flow over cold coils or evaporator coils that are packed with refrigerant. The moisture in the air condenses into water droplets when the temperature drops, and these droplets are either collected in a tank or drained away. After being slightly heated, the air that has become drier is then recirculated back into the space. This process will continue to cycle indefinitely until the levels of humidity that are required are obtained. Whether used in basements, crawl spaces, or entire homes, dehumidifiers are an essential tool for healthy indoor living.
How Loud is a Dehumidifier?
When considering a dehumidifier, one common concern is the noise level. Compared to appliances like power tools and blenders, dehumidifiers are generally considered quiet. However, since they often run continuously throughout the day and night, even a relatively quiet unit can become noticeable over time, especially in quieter settings or when you're trying to sleep.
To give consumers a clearer idea of how loud a dehumidifier can be, Consumer Reports conducted tests on various models. These tests involved placing a sound-pressure meter in front of each dehumidifier while running it at its highest fan and dehumidification settings. The meter was positioned 2 feet in front of the unit and 3 feet off the ground, simulating the noise level you might experience while sitting in the same room.
The results showed that the noisiest dehumidifiers reached around 70 decibels, which is comparable to the sound of a running shower. On the other hand, the quietest models operated at about 50 decibels, which is roughly the same noise level as a refrigerator—much more suitable for maintaining a peaceful environment, especially at night.
Although dehumidifiers are typically quieter than many household appliances, it’s important to choose the right model for your needs, especially if noise is a priority. Some of the quietest and most effective dehumidifiers are recommended by Consumer Reports, and their noise levels are listed alongside their water-removal capacities to help you make an informed choice.、

What Causes a Loud Dehumidifier?
Now that we’ve gone through the basics, let’s examine why dehumidifiers make noise in the first place. A dehumidifier makes noise mostly due to:
The Compressor
A compressor is used by the majority of dehumidifiers to cool the coils, which is an essential step in the moisture extraction process. The loudest sound produced during operation is usually the humming noise made by compressors. This sound is different from one type to the next; some compressors are made to be quieter than others.
Fan Operation
The fan raises the noise level in addition to its function of pulling in moisture-laden air and pushing out dryer air. The dehumidifier's noise level can be affected by the size and speed of its fans, which can make a whirring noise.
Motor Vibration and Water Dripping
As the accumulated moisture seeps into the water tank, you could also hear water leaking. Furthermore, noise may also be a result of motor vibrations, particularly if the dehumidifier is situated on an uneven surface. The noise may be amplified by vibrations, giving the impression that the device is louder than it actually is.
Factors Influencing the Noise Levels of Dehumidifiers
There are various things that can affect the sound level of a dehumidifier. By being aware of these aspects, you can choose a quiet and effective device.
Factor 1. Size and Capacity
Generally speaking, a dehumidifier's volume increases with its capacity. Because they are made to remove more moisture, high-capacity dehumidifiers typically have larger fans and compressors, which can raise noise levels. If you require a dehumidifier for a sizable space with a lot of moisture, you might have to give up some quiet in exchange for more effectiveness.
Factor 2. Room Size and Acoustics
The sound of a dehumidifier can also be influenced by the room's dimensions and acoustics. Sound can reverberate off walls in small, enclosed spaces, giving the impression that the dehumidifier is louder. On the other hand, the noise may not be as obvious in a larger space.
Factor 3. Fan Speed Settings
A lot of dehumidifiers include fan speeds that can be changed in strength. Although improved air circulation is usually associated with higher fan speeds, increased noise levels may also arise from them. Although it might take longer to lower humidity levels, lowering the fan speed can help make the dehumidifier quieter.
Factor 4. Component Quality
Modern technologies and high-quality parts can assist in minimizing noise. For example, Alorair dehumidifiers are designed with noise reduction in mind, utilizing top-notch fans and sophisticated compressors to reduce noise interference.
Ways to Cut Down on Dehumidifier Noise
There are various ways you can lessen the noise from a dehumidifier if you currently own one and find it to be too noisy:
- Put It Down on a Flat Surface:Make sure the dehumidifier is situated on a level, flat area. The device may vibrate due to uneven surfaces, which will increase noise levels. Another useful tool for cutting down noise and absorbing vibrations is adding a soft mat or carpet.
- Reduce the Fan Intensity:Try using a lower fan speed if you can. Even though the space may take longer to become dehumidified, lowering the fan speed can greatly diminish the noise level.
- Move the Unit: Think about putting the dehumidifier in a less accessible area. For instance, if it's in a bedroom and too noisy at night, you could move it to the hallway next door and leave the door open to let air flow.
- Continue To Do Routine Maintenance and Cleaning:Noise can be decreased by routinely cleaning the air filter and making sure the compressor and fan are operating at peak efficiency. The device may produce more noise when there is a blockage in the filter or a malfunctioning part, since it has to work harder to remove moisture.
