The MERV 11 Premium Allergen Air Filter captures unwanted allergens* and helps maintain optimal airflow in your home.
Traps particles such as pollen, household dust, dust mite debris, carpet fibers, lint, pet dander, smoke and smog.
Durable construction with a pleated surface with electrostatic charge and dual wire backing attracts particles to the filter and resists moisture.
Arrows on the frame indicate the direction of air flow, allowing for quick and easy installation.
