Filtering Out Discomfort, Illness
The Filtered Diffuser from Comfort First Products (Santa Ana, CA) is designed to eliminate drafts from overhead diffusers and reduce the illness and allergies caused by ductwork pollution. The diffuser allows users to adjust the angle the air enters the room on all four sides, helping to eliminate drafts or hot and cold spots. In addition, the MERV 14 electrostatic filters can collect particles as small as 0.3 µm at a 66 percent efficiency level, eliminating bacteria, mold, VOCs, and more from the air. The diffuser can provide up to three points for LEED certification.
