Bathrooms are high Humidity environments and are notoriously difficult to keep damp and mold free. Every time you turn on the shower or run a bath you’re creating an environment that mold and mildew just love. A Dehumidifier is an essential purchase if you hope to battle these unwanted additions to your Bathroom walls and ceilings.

Besides the threat of mold and mildew bathrooms can also develop musty odors if the moisture in the air isn’t properly taken care of. In bathrooms that don’t have their humidity controlled you are sure to find at least some small spots of mold or mildew on the ceiling or between tiles.
