Meet the Aerostar 16.50 x 21.50 x 0.75 inch MERV 11 pleated air filter, available as a convenient 4-pack for standard 1-inch filter slots. Designed for homes and small spaces, these filters blend reliable performance with straightforward maintenance. The actual size helps ensure a snug fit in many Bryant, Carrier, and Payne units, making an upgrade simple without guesswork.

These filters are proudly made in the USA, reflecting a commitment to dependable filtration and consistent production quality. You’ll notice the fit and finish work together with your HVAC system to deliver steady airflow and tidy, dust-free surroundings.

High-efficiency filtration without sacrificing airflow

The filter uses electrostatically charged synthetic media to trap particles in the 0.3–1.0 micron range, including lint, dust mites, mold spores, pollen, pet dander, fine dust, and smoke. With a MERV 11 rating (comparable to MPR 1200 / FPR 7), it aims to reduce common indoor irritants in homes and small offices.

• Traps a broad spectrum of particles to help improve indoor air quality.
• Electrostatic media captures fine particles while allowing normal airflow to continue.
• Designed for compatibility with a wide range of standard 1-inch HVAC systems.

Durable design built for real-life use

A sturdy pleated construction pairs a beverage board frame with wire backing to resist humidity and temperature shifts. The pleats increase surface area for longer filtration life, so you won’t need to replace as often as you might with thinner filters.

• Durable frame withstands daily HVAC operation and environmental changes.
• Longer-lasting filtration due to increased surface area from pleating.
• Simple, cost-effective step toward a cleaner indoor environment.

Usage guidance and compatibility

For best results, replace every 60–90 days under normal use. In peak summer and winter months when the system runs hardest, consider replacing closer to every 30 days to maintain performance. The filter is compatible with furnaces and air conditioning units and replaces common Bryant/Carrier Paynes in the listed configurations.

Choose Aerostar for a dependable, USA-made filtration option that supports cleaner air and smoother HVAC operation without overpromising results.
