StrataClean IQ Air Filtration System is an in-ceiling system that captures and eliminates airborne bacteria, viruses, mold and other particulates using proven MERV 13 filtration. The system uses an internal fan to draw air through one side of the grille. The air then moves through a 2” MERV 13 filter and discharges back into the space through the opposite side of the grille. With the fan continually running, the air in the occupied space is constantly filtered to provide clean, purified air.
