The Aerostar 20x25x1 MERV 11 Pleated Air Filter is designed for most standard residential and commercial HVAC systems with a 1-inch filter slot. The actual size is 19.75 x 24.75 x 0.75 inches.

The filter uses electrostatically charged synthetic material to capture airborne particles and allergens between 0.3 and 1.0 microns, including lint, dust mites, mold spores, pollen, pet dander, fine dust, and smoke.

The pleated construction provides more surface area for filtration, while the sturdy beverage board frame and wire backing are designed to resist humidity and temperature changes. The filters are manufactured in American facilities using high-quality materials.
