Filtrete - 16 in. W X 20 in. H X 1 in. D Polypropylene 700 MPR Pleated Air Filter 1 pk - Case of 4

The 20x24x1 filter is engineered to capture countless microparticles such as pet dander, smoke, smog, bacteria, and up to roughly 54% of small virus‑carrying particles, while also grabbing larger debris like lint, dust, pollen, mold spores, and dust‑mite matter. Intended as a 3‑month residential filter, it fits standard 1‑inch filter slots and provides a strong upgrade over fiberglass or basic washable filters when changed on schedule.

Crafted to support cleaner indoor air, this pleated air filter works within your HVAC system to capture particles as air circulates through your home. Its electrostatically charged polypropylene media is designed to attract and trap dust, pollen, pet dander, lint, mold spores, and dust‑mite debris while helping maintain effective airflow in compatible equipment. Intended for single use, it should be replaced periodically—often every one to three months depending on system runtime, occupancy, and indoor air quality conditions—and is not suitable for washing or reuse.

Formulated for standard residential heating and cooling systems, this electrostatically charged polypropylene pleated filter works to capture everyday household particles such as dust, lint, pollen, and pet dander as air recirculates through your home, contributing to cleaner indoor air when changed on a typical three‑month schedule. The 700 MPR (MERV 8‑level) media provides better filtration performance than basic fiberglass filters.
