Genuine Daikin 2088330 Indoor Front Grille Assembly is the front panel of the indoor unit that draws room air in through its intake and houses the filters behind it. When it cracks, warps, or loses clips it can sit unevenly, rattle in airflow, or fail to hold the filters square. The genuine front grille is moulded to the unit's exact shape and clips, sitting flush and secure where a generic substitute can gap or flex.
