Your basement is likely to be the most humid room in the house. Basements are often poorly insulated and have few, if any, windows, resulting in inadequate ventilation. Consequently, the air in basements often holds larger volumes of water vapor and is more humid. A dehumidifier can remove this moisture and reduce humidity levels, but will a dehumidifier in a basement help upstairs?
Humidity is a measure of water vapor in the air – the more moisture there is, the higher the humidity will be. A comfortable humidity is between 30% and 50% according to the Centers for Disease Control and Prevention (CDC). Anything above this can make the room, or your whole house, feel stuffy. It can also encourage mold, mildew and dust mites.
