Reasons for Choosing a Silent Dehumidifier

One of the particularities of dehumidifiers is that they can be very noisy due to the fans that rotate when absorbing water from the air. Many people buy a dehumidifier then regret not having inspected its specifications and analyzing its noise level. Usually, dehumidifiers are set to start when they detect a high level of humidity, which can happen at any hour so, having a unit that sounds like a chainsaw is not the most appealing choice.

No disturbance

It’s best to have a dehumidifier that makes less noise because it will not disturb you in any way. If you pick one for the basement, you might not be interested in how quiet it is but things change when you install the unit in a living room or a bedroom. A low operating noise will allow you to keep the unit running at any hour without having to worry about it being too loud.

High performance with low noise

Usually, the smaller the unit, the quieter because the motor that powers it and the fans make less noise. Small units are quieter than the large models but sometimes you might need a large unit that is also quiet. For times when you need a heavy-duty device with a quiet operating, you must know which are your best options.

Usual Dehumidifier Noise Output

Due to the fact that most dehumidifiers use fans and compressors to draw in the air in a room, they are likely to get noisy especially after extended use. If you want one for the bedroom or an office, the last thing you will want to hear is a buzzing sound at all times. Fortunately, you can choose silent units that will operate at extremely low noise levels.
Aside from the noise created by the running compressor, you will also experience the noise made by the intake fans placed on the front and exhaust fans located either at the top or the sides. Models with the exhaust located at the top are louder than the ones with the exhaust on the side because the air is evacuated closer to your hearing range. These aspects are worth considering when rating a dehumidifier silent or not.
In order to be able to select a device with a low noise output, you must first know which is the sound range so that you will know your boundaries. Firstly, note that dehumidifiers have several speed levels so the noise output will differ according to the speed you select. We have rated our picks according to the noise level on the lowest speed because this is how you will likely keep it.
Normally, a silent unit releases around 48 dB on the lowest speed setting and can exceed 60 dB on the highest speed. The average sound level is around 50 dB so this should be the number to look for. Of course, the sound can differ according to the intensity of the operating meaning that if the device is too small for the room, it is likely to seem overburdened and to get noisier. Also, if you don’t clean the compressor and allow scale buildup, the device is likely to make more noise. Units that create over 50 dB on the lowest speed and exceed 70 Db on the highest are not considered as silent so they are not part of this category.
Where you place the dehumidifier is also related to its noise output because the closer you sit to it, the louder you will hear it. Also, if you place it near walls or furniture, the fans will get noisier as they will intake and exhaust the air.

    What is the maximum noise level a dehumidifier can reach? How can you tell how silent these models are?

      Usually, the noise level depends on the size of the unit and the humidity settings. Most large models reach a maximum of 66 dB, which is why we considered the selected models to be quiet at a maximum of 56 dB at a high speed.
