Air Handler Washable Electrostatic Air Filter, 20x20x1, Polypropylene, MERV 5, 381 sq ft Media Area

Washable electrostatic air filters naturally create a static charge as air moves through the filter, and the charge attracts tiny particles such as dust and pet dander. These electrostatically charged filters are installed in HVAC systems to remove airborne contaminants from the air stream to improve indoor air quality. Dirty filters can be washed and reused, which eliminates the hassle and expense of purchasing and storing replacement filters.
