Aerostar 20x25x1 MERV 8 Pleated Air Filter, 4 Pack, Furnaces Filter, HVAC Filter

The Aerostar 20x25x1 MERV 8 pleated air filter is a replacement furnace filter for home HVAC, AC, vent, and air conditioner systems. Each filter has a nominal size of 20x25x1 and an actual size of 19.75x24.75x0.75. Measure your existing filter before ordering to confirm fit in your HVAC slot. The 4-pack provides up to months of replacement furnaces filters at the recommended 90-day change interval. 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. The pleated design uses electrostatically charged synthetic media to attract and hold particles more effectively than flat fiberglass filters. Low airflow resistance helps maintain HVAC efficiency. The reinforced moisture-resistant frame prevents filter collapse and air bypass. Compatible with most major brands including Carrier, Bryant, Trane, Lennox, Rheem, Goodman, York, Ruud, and Honeywell 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. Made in USA.
