Air Filter Merv Ratings: MERV 10
ASHRAE MERV rating cross-reference per ANSI/ASHRAE Standard 52.2 — MERV 1 through 16 with efficiency range group (E-1/E-2/E-3), particle size range controlled, arrestance value (MERV 1-4), example contaminants, typical HVAC applications, and representative filter media types.
| merv rating | efficiency range group | example contaminants | filter types | standard | typical applications |
|---|---|---|---|---|---|
| MERV 10 | E-2 | 1.0 to 3.0 µm size range: milled flour; lead dust; combustion soot; Legionella; coal dust; some bacteria; process grinding dust | Box-style wet-laid or lofted fiberglass; box-style synthetic media; minipleated synthetic or fiberglass paper; depths from 2 to 12 in. Pocket filters either rigid or flexible in synthetic or fiberglass; depths from 12 to 36 in. | ASHRAE 52.2-2017 | Food processing facilities; air separation plants; commercial buildings; better residential; industrial air cleaning; prefiltration to higher-efficiency filters; schools; gymnasiums |
