Filtrete 20x25x4 Air Filter MERV 11 | MPR 1000 Micro Allergen Defense 4-Pack | Fits Honeywell & Aprilaire

Cleaner air, smarter filtration for your home

Filtrete 20x25x4 MPR 1000 Micro Allergen Defense filters, crafted by 3M, bring a thoughtful approach to indoor air. With exclusive Filtrete 3-in-1 technology and a combined MPR 1000 / MERV 11 rating, this filter is designed to pull in and trap a wide range of particles, while still supporting healthy airflow through your HVAC system.

Imagine stepping into a room where the air feels crisper and easier to breathe. This filter targets countless microparticles—like pet dander, smoke, and smog—while also catching larger irritants such as lint, pollen, mold spores, and everyday dust. The result is a home environment that can feel fresher and more comfortable across living spaces and rooms.

In practice, you may notice improved airflow and potentially quieter HVAC operation as the system works with a higher-efficiency filter. While experiences vary by home, many users appreciate the sense of cleanliness and reliability that comes with upgraded filtration. This filter is designed to fit residential systems that call for a 4.31-inch thick filter, with an actual size of 19.88 x 24.63 x 4.31 inches, making it a precise 4-inch deep replacement for compatible units.
