Aerostar's 20x22x1 MERV 11 Pleated Air Filters (Actual Size: 19 3/4" x 21 3/4" x 3/4") come in a 6-pack and are designed for superior filtration efficiency. These filters are made with electrostatically charged synthetic material that draws and captures allergens between 0.3 - 1.0 microns, including lint, dust mites, spores, pollen, pet dander, fine dust, and smoke.

Comparable to MPR 1000-1200 and FPR 7, these MERV 11 filters are a simple and cost-effective step towards a healthier home environment, free of airborne allergens and particles that can trigger various allergy and asthma symptoms. They also improve the efficiency of your HVAC unit, reducing maintenance and utility costs by removing dirt and reducing strain on the motor.

For optimal performance, it is recommended to change the filters every 60 to 90 days, with increased frequency to 30 days during peak summer and winter months when the unit is working the hardest. Aerostar's air filters are compatible with both furnaces and AC units.

Manufactured by Filtration Group, a world-leading manufacturer and supplier of filtration solutions, these 100% synthetic electrostatic media filters provide high efficiency with low air flow resistance, making them a reliable choice for maintaining a cleaner, healthier indoor environment.
