DESC: These Whirlpool Dehumidifiers can operate in temperatures as low as 44° F without icing up making them usable in any room almost year round, even in your basement. Lowering the humidity can make a big difference in the mite population inside your entire home. Plus, allergenic fungus growth, like mold and mildew, is also controlled since it needs high humidity levels to thrive. Lower humidity takes care of mildew odor as well.
