Aerostar 21 1/2x23 1/2x1 MERV 11 Pleated Air Filter, 6 Pack

The Aerostar 21 1/2x23 1/2x1 AC and Furnace Air Filter is a MERV 11 pleated filter designed to provide superior filtration efficiency. Manufactured in the USA by Filtration Group, a leading provider of filtration solutions, this filter is comparable to MPR 1000 to 1200 and FPR 7 ratings.

Featuring a 100% synthetic electrostatic media, the Aerostar filter is engineered to effectively capture a wide range of microscopic particles, including lint, dust mites, spores, pollen, pet dander, fine dust, and smoke. The electrostatically charged material draws in and traps these allergens, helping to improve indoor air quality and create a healthier home environment.

By removing dirt and reducing strain on the HVAC unit's motor, the Aerostar filter helps to maintain the system's efficiency. This, in turn, can lead to reduced energy consumption, lower maintenance costs, and a longer lifespan for the unit. Homeowners are recommended to change the filter every 60 to 90 days during normal usage, and increase the frequency to 30 days during peak summer and winter months when the system is working the hardest.

The Aerostar brand is known for its commitment to innovation and continuous improvement in filtration technology. This MERV 11 filter is a cost-effective step towards enhancing indoor air quality and protecting family members from airborne allergens and particles that can trigger allergy and asthma symptoms.

Each box contains six Aerostar MERV 11 pleated furnace air filters, with a nominal size of 21 1/2x23 1/2x1 and an actual size of 21 1/2" x 23 1/2" x 3/4". The simple installation process and the filter's effectiveness in trapping microscopic pollutants make it a valuable addition to any home's HVAC system.
