Is this your unit?

The model number is on the label on the side of the unit or inside its front panel. It starts with TWE049E. This page also covers TWE049E13, TWE049E13F, TWE049E13FB. The same units are sold as American Standard.

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.
