Filtrete Filter Ultra Allergen

The Filtrete line of best performing filters capture at least 90% of large airborne particles like dust, pollen and pet dander from the air passing through the filter. They also outperform all non-electrostatic filters. Lasts up to 3 months. Filtrete filter media is electrostatically charged to act like tiny magnets to attract and capture microscopic particles from the air as it passes through the filter.
