Our patented SaniDry Sedona dehumidifier is the perfect solution for preventing the growth of mildew and filtering the air in your crawlspace. Due to the "smokestack" effect, the air in your crawlspace travels up through the rest of your home which can be harmful to your health if not addressed. Our dehumidifier is designed specifically for crawlspaces and basements, keeping the relative humidity at 55%. It also has a MERV 8 filter that keeps mold and mildew out of the air you breathe.
