Filtrete™ Basic Dust Reduction Filter (MPR 300)

Filtrete's entry-tier 1" pleated air filter with MPR 300 (≈MERV 5). Captures large dust particles, lint, and household dust. Made by 3M. What MPR 300 actually means. MPR 300 is roughly equivalent to MERV 5. The pleated media captures the larger end of the household particle range — visible dust, lint, and large pollen — while keeping airflow restriction low. Not intended as a fine-particle or allergen-grade filter. Who it's for. Light residential and small commercial use where basic dust capture is the priority and airflow needs to stay maximized. When to replace. Every 90 days under typical conditions; every 30–60 days in dusty environments or with pets. Inspect monthly — if light no longer passes through the pleats, it's time to change. Sold in cases of 4. Order quantity must be a multiple of 4. Cases ship in original 3M packaging. About this product line.
