Aerostar 16x25x4 MERV 11 Deep Pleat Air Filter, AC Furnace HVAC, 2 Pack

Keep your home air clean and your HVAC system running efficiently with the Aerostar 16x25x4 MERV 11 pleated air filter. This disposable 16x25x4-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 a wide range of airborne contaminants including dust, pollen, pet dander, mold, and smoke particles, making it an effective allergy filter for homes with pets or seasonal sensitivities. 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 16x25x4 with an actual measured size of 15.5x24.5x3.75, designed for easy installation into standard return air vents and filter grilles. This 2-pack provides 4 to 6 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 filters in the same 16x25x4 size for basic protection at a lower price, and MERV 13 for maximum residential filtration including bacteria and viruses.
