Filtrete 20x25x1 MERV 11 Furnace Air Filter, 3-Month 6-Pack

High-Performance HEPA Air Filters

Outperforming Fiberglass Filters

Our 3-month pleated 1-inch air filters outperform traditional fiberglass filters by trapping a greater number of microparticles. Choose filters designed specifically for your furnace, air conditioner, or HVAC system.

Exclusive Filtrete 3-in-1 Technology

Crafted with Filtrete's proprietary 3-in-1 technology from 3M, these filters are engineered to trap unwanted air particles while allowing cleaner air to flow through.

Effective at Capturing Particles

These filters attract and capture a wide range of particles, including lint, pollen, dust, pet dander, smoke, and smog, ensuring your indoor air stays fresh and clean.

MPR 1000 with MERV 11 Rating

Our MPR 1000 filter boasts a MERV 11 rating, meaning it can capture up to 98% of microparticles. The higher the MPR, the more microparticles—such as pollen, pet dander, smoke, bacteria, and viruses—the filter will remove from the air passing through.

Available Sizes

Find the perfect size for your system with our range of filters available in 4-inch, 4-inch slim fit, and 5-inch thick options.
