Filtrete - 12 in. W X 24 in. H X 1 in. D 300 MPR Pleated Air Filter 1 pk

This pleated dust and lint filter helps reduce everyday airborne particles—such as household dust, lint, and dust mite debris—as air circulates through your heating and cooling system, and works best when replaced about every 90 days. The electrostatically charged 300 MPR (MERV 5) media is designed to pull in and trap larger, common particles while allowing reliable airflow through standard 1‑inch residential furnace and AC filter slots.
