Wall-Mounted Units

Open the front panel by gently lifting from the bottom corners. The panel pivots upward and locks into place. Two washable mesh filters are visible — they slide out from the bottom. Clean every 2-4 weeks during heavy use.

Ceiling Cassette Units

The air filter is accessed through the bottom grille of the ceiling cassette. Most have a visible pull tab or latch. Some models drop down on hinges for filter access. Filters are similar mesh type located around the air intake perimeter.

Floor-Mounted Units

Floor-mounted units (console type) have the filter behind a front panel that lifts up or slides off. The filter is typically at the top of the unit. Access and cleaning is similar to wall-mounted units. Always turn off the unit before opening the panel.
