Filtrete - 20 in. W X 20 in. H X 2 in. D Polypropylene 1000 MPR Pleated Air Filter 1 pk - Case of 4

The Filterbuy replacement air filter 6.88x15.88x1 (actual size: 6.88" x 15.88" x 0.75") ensures that your furnace, air conditioner, heat pump, or HVAC system is circulating the cleanest air possible to help preserve your budget and healthy lifestyle. MERV 8 synthetic media (comparable with Clean Living Dust Defense MPR 700 & FPR 5) is recommended in most scenarios with its capability to trap 90% of dust particles while protecting your home or business from lint, pollen, mold, dander, and other forms of debris without impacting air flow. High quality construction features an electrostatically charged design with 14 pleats per foot that captures more harmful particles and prolongs the products lifespan by three times that of fiberglass models (replace every 90 days for best results). Plus, our industrial grade beverage board frames are paired with dual wire backings that significantly outperform traditional cardboard compositions by improving structural integrity with their ability to endure temperatures up to 200 degrees Fahrenheit and withstand exposure to moisture. Installation is also made simple with the addition of easy-to-understand arrows that help identify the direction of air flow and subsequently the way the filter needs to be placed. To top it off, all our components are 100% manufactured within the United States and designed with recyclable materials, providing an eco-friendly alternative to enhancing your air quality.

Air circulation in central systems constantly carries fine allergens back to the return, where this pleated panel is designed to intercept them. In the 1000 MPR (MERV 11) performance tier, the 20x24x1 Micro Allergen Defense filter uses electrostatically charged polypropylene media to capture a broader mix of particles than basic dust filters, including household dust.

Designed as a step‑up option from basic HVAC filters, this 2‑inch pleated model helps your system capture more airborne material every time it cycles on. Its electrostatic polypropylene media, rated 1000 MPR, actively attracts fine particles such as pet dander, smoke, and smog while also collecting common debris like dust, lint, pollen, and mold spores as air passes through.
