Aerostar's 20x22x1 MERV 11 Pleated Air Filters (Actual Size: 19 3/4" x 21 3/4" x 3/4") are available in a 4-pack, providing a simple and cost-effective solution for improving indoor air quality. These filters are designed to capture a wide range of airborne allergens and particles, including lint, dust mites, spores, pollen, pet dander, fine dust, and smoke, effectively removing them from the air.

The MERV 11 rating of these filters is comparable to MPR 1000-1200 and FPR 7, ensuring superior filtration efficiency. The filters are made with electrostatically charged synthetic material that draws in and captures particles as small as 0.3 - 1.0 microns, helping to create a healthier home environment and reduce the triggers for various allergy and asthma symptoms.

By improving the efficiency of HVAC units, these Aerostar filters can also help to lower maintenance and utility costs. The filters' ability to remove dirt and reduce strain on the motor contributes to enhanced system performance and energy savings.

For optimal results, it is recommended to change the filters every 60 to 90 days. However, during peak usage periods in the summer and winter months, when the HVAC unit is working the hardest, the frequency should be increased to every 30 days. This regular filter replacement ensures continuous air filtration and the maintenance of a healthy indoor environment.
