Camfil Farr Riga-V™ provides high efficiency rigid filtration performance at an economical price. Available in three ASHRAE (MERV 11, 13 and 14), the filters offer greater dust holding capacity and lower pressure drop than most comparable filters at a lower first cost. The key to the filter’s economical performance is a high-lofted synthetic media in a proprietary V-pleat configuration that produces optimized performance. Benefits include excellent dust loading and airflow characteristics for longer service life and lower average energy costs. The frame components create a rigid media support system to ensure dependable filtration performance under varying airflow conditions.
