Dehumidifier options that are considered to be 100% silent are mostly made from desiccant. Because some but not all of the desiccant dehumidifiers are manufactured without any type of motor that can produce noise. However, these units are usually expensive and work slower to extract moisture from the air when compared with compressor units.

Therefore, below we have put together a list of the most quietest dehumidifiers we have tested using decibel meter. Our tester placed the decibel meter in front of the running dehumidifier at its full speed approximately 2 feet in front and 2 feet high above ground simulating an ideal placement within most homes.

The reason why we have selected these dehumidifiers even though they are not all desiccant is due to the fact that most home settings require fast and efficient moisture removal and these are some of the quietest and most effective ones we found through our testing and research.

The Bottom Line

We understand that the last thing you want in your home is a noisy appliance. This is why we took decibel measurements into account when compiling the list of our quietest dehumidifiers. Dehumidifier noise can be a real pain especially when the unit is placed near your bedroom, study room, or nursery.

When testing the above units, we cranked up each model to its highest moisture-removal setting and fan speed. We consequently placed each unit in a quiet room and turned them on to determine how they might sound like, especially when you’re relaxing in a serene environment with them running. With a low noise level below the 60dB line, we can safely say that the above dehumidifiers are super quiet. Their noise level isn’t more than the sound of two people having a conversation.

Based on our findings, the manufacturers of these units utilize superior-quality compressors to reduce the noise levels. Others strategically place the air outlets on top of the units to control the noise. Some manufacturers will also reduce the number of filters and moving parts, which are typical culprits of high noise production.

Whichever method is used to reduce the noise, we can recommend the above units for their efficient extraction of indoor moisture without creating noise disturbances, affording you a peaceful night sleep, relaxation, or study.
