Filtrete - 20 in. W X 30 in. H X 1 in. D Polypropylene 700 MPR Pleated Air Filter 1 pk - Case of 4

This electrostatically charged polypropylene media, with a 700 MPR (approximately MERV 8) rating, is formulated to attract and capture common airborne particles such as lint, household dust, pollen, and pet dander while still allowing effective airflow through compatible systems. The 1‑inch thickness fits many standard filter slots and supports routine air‑quality maintenance in the home. Intended as a disposable filter.

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.

Built for everyday residential HVAC use, this pleated polypropylene filter helps reduce common airborne particles—including dust, lint, pollen, dust mite debris, and pet dander—as air moves through your heating and cooling system, and works best when replaced about every 90 days. The electrostatically charged media with a 700 MPR (approximately MERV 8) performance level provides improved particle capture compared to basic non-pleated filters.
