The Camfil Farr Riga-V? air filter provides high-efficiency filtration. Available in three ASHRAE efficiencies (MERV 11, 13, and 14), the filter offers greater dust-holding capacity and a lower pressure drop. It may be used in commercial buildings, schools, health care facilities, industrial plants, utilities, and other applications. A high-lofted synthetic medium in a V-pleat configuration produces optimized performance. The frame components create a rigid, media support system to ensure filtration performance under varying airflow conditions.
