Elevate your indoor air with Aerostar

The Aerostar 20x25x4 MERV 11 pleated air filters arrive as a convenient 6-pack, sized at 19.50 x 24.50 x 3.75 inches for standard 4-inch slots. Designed to balance filtration and airflow, these filters sit between typical consumer options and premium solutions, offering an accessible upgrade to your home or office air quality. They align with MPR 1200 and FPR 7 benchmarks, providing a dependable layer of defense against common airborne particles without overburdening your HVAC system.

In everyday use, you’ll notice cleaner air in living rooms, bedrooms, and workspaces, along with a smoother, quieter system performance. This isn’t a guarantee of medical outcomes, but many users report fewer irritants circulating in the air your family breathes.

What makes these filters stand out

  • High-efficiency filtration: Captures a broad range of particles, including dust, pollen, spores, pet dander, and smoke, helping to reduce irritants in the air you breathe.
  • Electrostatically charged media: Attraction-based filtration helps trap fine particles while maintaining airflow for HVAC efficiency.
  • Durable, pleated construction: A sturdy frame with wire backing resists humidity and temperature changes, delivering longer-lasting filtration.
  • Universal compatibility: Fits most standard 4-inch filter slots in homes and small businesses, including Lennox, Carrier, Bryant, Payne, and Honeywell systems.

Why this matters for your space

  • Cleaner air daily: A practical step toward reducing common indoor allergens and particles in active spaces.
  • Possible improvements in HVAC efficiency: By removing dirt, filters can help ease the load on the motor, potentially supporting steadier system performance.
  • Flexible maintenance schedule: Replace every 60–90 days under normal use, or more frequently (around 30 days) in peak heating or cooling seasons.
