The Comfort First Filtered Diffuser - Commercial Filtered Diffuser 4-Way Vent Diverter comes with MERV 12 filters and traps any pollutants or particles as small as .03 microns in size. With the high ability to filter, this air diffuser is at a 40.6% efficiency level at 150 fpm. This easy-to-install air diffuser works with any 24" × 24" drop ceiling with a T-bar grid system or Fineline system. A more efficient MERV 14 filter is also available. Whilst the CFFD was designed as a 2' × 2' air diffuser for drop ceilings it can also easily be mounted on hard ceilings thanks to our surface mount back pan.
