About this item
Product details
Keep your home air clean and your HVAC system running efficiently with the Aerostar 21x21x1 MERV 13 pleated air filter. This disposable 21x21x1-size HVAC filter is a direct replacement furnace filter and AC filter for any standard residential or commercial forced air system. Engineered with electrostatically charged synthetic filter media, each filter actively attracts and captures the widest range of residential airborne contaminants including dust, pollen, pet dander, mold, smoke, bacteria, viruses, and odor-causing particles for maximum home air filtration. The pleated design provides significantly more surface area for particle capture than basic fiberglass panel filters while maintaining low air resistance for efficient airflow through your heating and cooling system. This means better indoor air quality and lower energy costs. The nominal size is 21x21x1 with an actual measured size of 21.5x21.5x0.75, designed for easy installation into standard return air vents and filter grilles. This 4-pack provides approximately 8 to 12 months of replacement air filters for homes with a single HVAC return. Replace every 60 to 90 days under normal conditions, or every 30 days during peak heating or cooling seasons, in homes with pets, or where household members have allergies or respiratory sensitivities. Every Aerostar air filter is proudly manufactured in the United States by Filtration Group, one of the leading filtration companies. Aerostar also offers MERV 8 and MERV 11 filters in the same 21x21x1 size for homes that do not require maximum filtration at lower price points.

not a good filter.
very flimsy filters. These are not very good for AC units. The filter does not have a good bulild as it bends easily and does not stay in the tray as intended. I would not recommend this filter for allergies.
