We are providing sound level information to help you understand the expected level of sound from a Dehumidifier. Within a compressor or refrigerant type dehumidifier there is a compressor that is similar to that of your refrigerator plus a fan motor. The compressor operates only when dehumidification is required. With a number of dehumidifiers the circulation fan will continue to operate even when dehumidification has ceased, though some machines will shut down completely
Many customer often ask about using the dehumidifier in a bedroom. The use of a dehumidifier in a bedroom is not really a good idea as sound may disturb plus some additional warmth from the dehumidifier may not always be welcomed. We sell both compressor type dehumidifiers and absorption dehumidifiers with latter often being the quietest of dehumidifiers, particularly when set to low fan speed. While absorption dehumidifiers are generally used in dwellings where internal temperatures may fall they can of course be used in the home and may well be the better choice of dehumidifier if you are going to use it during the night.
Will sound levels bother you if you use it in a bedroom? If so then you may wish to use the dehumidifier during the day or evening to reduce humidity and then switch the unit off before you go to sleep. However, with many dehumidifiers, in particular the Desiccant or Absorption types they can be used during the night with refrigerated dehumidifiers better off being used away from bedrooms.
