3M FILTRETE PRODUCTS UR04-2PK-6E Ultra Allergen Reduction Filter 14" X 25" X 1" 2-Pack

The 3M FILTRETE PRODUCTS UR04-2PK-6E Ultra Allergen Reduction Filter 14" x 25" x 1" 2-Pack removes suspended particles from circulating air by trapping pollen, household dust, smoke particles, and other airborne material within its filtration media. As air passes through the filter, captured contaminants remain in the media while filtered air continues through the equipment's airflow path. Installed in the return-air or intake section, it fits the filtration assembly used in HVAC systems and works with the air-handling equipment during heating and cooling operation.
