16x20x4 pleated HVAC air filters in MERV 8, 11, and 13 — for homes, offices, schools, healthcare, and commercial facilities. Bulk, contract, net-30, and tax-exempt ordering available, shipped fast across the U.S.
Captures everyday dust, lint, and pollen — a solid baseline for homes and light commercial spaces.
Captures finer dust, mold spores, and pet dander — a common upgrade for offices and allergy-sensitive areas.
Captures smoke, bacteria, and the smallest airborne particles — preferred for schools, healthcare, and high–air-quality facilities.
16x20x4 is the nominal size — the number printed on the filter frame (16" × 20" × 4"). The actual cut size is typically a touch smaller so the filter seats easily in the slot or grille. If you're unsure, read the size printed on the edge of your current filter and match it exactly. This size is a 4-inch pleated panel. 4-inch panels hold more dust and last longer between changes than standard 1-inch filters.
How often to replace: most facilities change 1" pleated filters every 60–90 days; high-traffic commercial and institutional buildings often change more frequently. Ask us about a scheduled replacement-supply program so you never run out.
