Washable Fan Filter - Made for 30" Industrial Drum Fans. FILTER ONLY, fan not included. INDUSTRIAL 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 industrial grade filter is made to treat indoor air quality problems in schools, hospitals, office buildings, and retail, manufacturing and warehouse facilities. THE SCIENCE: Our proprietary PollenTec air filter technology coupled with a dense support layer of antimicrobial filtration media allows our hypoallergenic fan filters to purify the air for your employees with ease. 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 so effective that they have been tested, approved, and used in hospital clean rooms. ALLERGY CERTIFIED & FLAME RETARDANT: Our fan filters have been awarded a formal certification from the European Center for Allergy Research Foundation (ECARF). Our filters are proven to capture up to 98% of airbone pollen allergens and both large and small particles in the air such as dust, pollen, dust-mite debris, mold spores, and pet dander. In addition, they are 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 that will end up in already overflowing landfills after disposal. Simply follow the provided washing instructions 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.
