MERV 8 filtration captures common household airborne particles including dust, pollen, pet dander, pet hair, mold spores, and lint. It does not capture bacteria, smoke, or virus-sized particles. For higher filtration of those particles, select a MERV 13 filter. Designed for furnace air, AC, heater, and house air return applications. Pleated electrostatically charged synthetic media captures more particles than flat fiberglass filters while maintaining low airflow resistance to support HVAC system efficiency. The reinforced moisture-resistant frame prevents filter collapse and air bypass over the filter's life. Compatible with most major brands including Carrier, Bryant, Trane, Lennox, Rheem, Goodman, York, Ruud, Honeywell, and Aprilaire furnace and air conditioner systems. Replace every 90 days under typical conditions, or every 30 days in homes with pets, smokers, or high dust levels for allergy and asthma relief. Made in USA.
