Aerostar 20x20x1 MERV 11 Filter – 6 Pack (Actual Size 19.75 x 19.75 x 0.75) – Made in USA

Elevate your indoor air with Aerostar

The Aerostar 20x20x1 MERV 11 pleated air filters come in a convenient six-pack. Each filter is cut to the exact 19.75 x 19.75 x 0.75 inch actual size, designed to fit most standard 1-inch filter slots. Built with electrostatically charged synthetic media, these filters are engineered to capture a broad range of airborne particles as air passes through the media, helping to keep your living spaces cleaner and more comfortable.

What makes these filters stand out

• High-efficiency filtration: MERV 11 filtration (comparable to MPR 1200 / FPR 7) helps reduce common irritants like dust, pollen, mold spores, pet dander, and smoke.
• Fine particle capture: The media targets particles in the 0.3–1.0 micron range while allowing steady airflow for consistent HVAC performance.

Durable design and universal compatibility

• Durable, pleated construction with a wire-backed frame resists humidity and temperature fluctuations, delivering longer-lasting filtration in busy homes or small offices.
• Universal compatibility ensures a good fit for most standard residential and commercial HVAC systems with a 1-inch slot, including popular brands like Carrier, Bryant, Payne, and Honeywell.

Performance, efficiency, and practical usage

Beyond filtration, these filters are designed to support your HVAC system’s efficiency. By removing dirt and reducing particle load, they can help minimize motor strain and maintenance needs. Changing frequency is flexible: aim for every 60–90 days, and shorten to about 30 days during peak summer and winter months when the system runs hardest.

Made in the USA for reliability
