If your filter isn't in the unit

Many closets have the filter behind a grille on the door, wall or ceiling instead. That one is sized by the grille, not the unit. The size is printed on the filter's edge, or you can photograph it on our home page.

Size from Rheem's product specifications. If it doesn't fit, our fit guarantee sends a new one free. Caliper isn't affiliated with or endorsed by Rheem.
