Effective, Affordable, Easy to Clean

FAN NOT INCLUDED: The product includes the single filter only and NOT the actual fan shown in the product photo that was used for demonstration purposes. This filter is sized for a box fan with a fan blade diameter of 20’’ with a case/housing that can be 21.5’’ x 21.5’’ or 20.5" x 20.5". When a box fan company refers to 20’’ in their product name, it refers to the fan blade diameter and not the case/housing size. Please contact us before ordering if you are unable to verify what your box fan case/housing size is.

THE SCIENCE: Our proprietary PollenTec air filter technology. PollenTec is a high-tech spun polyester possessing special triboelectric properties that electrostatically pulls and traps particles on its fine fibers for filtering. Our filters are highly effective, long-lasting and easy to clean.

ALLERGY CERTIFIED & FLAME RETARDANT: Our PollenTec filtration material has been awarded a formal certification from the European Center for Allergy Research Foundation (ECARF). Proven to capture up to 98% of airborne pollen allergens and both large and small particles in the air such as household dust, pollen, dust-mite debris, mold spores, and pet dander. In addition, thr dense layer of Poly-Flo is flame retardant and self-extinguishing certified (UL & FMVSS302 certifications).

WASHABLE / ENVIRONMENT-FRIENDLY: The fan filter is washable, reusable, and most importantly economical. No more having to buy replacements every couple of months like the furnace air filter for your home that will end up in already overflowing landfills after disposal. Simply follow the provided washing instructions below and the filter will pop out as if it were brand new, wash after wash, for years on end.

MADE IN THE USA: We are proud to announce that we are the only reliable filter supplier in our Amazon niche to have all stages of manufacturing completed within the United States, unlike others who outsource production to China and Mexico. Such decision is resiliently reflected in the build quality and reliability of our air filters and exemplifies our proud support of contributing to American jobs.
