4055387445 Genuine Indoor Unit Filter Grid for Electrolux Group Split System Air Conditioners, Air Filter Mesh Screen

Part 4055387445 is the genuine Electrolux filter grid for the inner unit of a split system air conditioner. This is the mesh screen behind the front panel that catches dust before it reaches the coil. Order a new one if the old grid is torn, warped, missing or no longer clips in firmly. Check that the number on the frame or in your manual reads 4055387445 before buying.

Why a damaged air conditioner filter matters

Every bit of air the indoor unit moves passes through the filter grid first. A clean, intact grid keeps dust and lint off the evaporator coil and the fan. Once the mesh tears or the frame cracks, dirt gets straight through, the coil clogs, airflow drops and the unit struggles to heat or cool the room. You may also notice musty smells, ice on the coil in cooling mode, or water dripping from the indoor unit. Regular cleaning helps, but a damaged grid should be replaced.

Fitting the filter grid

Turn the unit off with the remote and at the isolator. Lift the front panel until it holds open, slide the old grid down and out, then slide the new one in along the same guides until it sits flat. Close the panel and run the unit. During heavy use, clean the grid every few weeks.

Questions about this part

Is there a left and right filter?

Many indoor units take two grids side by side, and some use different left and right versions. Look at the numbers on both of your old grids and order 4055387445 for each position that carries this number.
