The Riga-V air filter provides low-cost, high-efficiency rigid filtration performance, according to this company. The filter is available in MERV 11, 13 and 14. Applications include commercial buildings, schools, health care facilities, industrial plants and utilities. The filter's performance is due to its high-lofted synthetic media in a proprietary V-pleat configuration. The frame components create a rigid media support system to ensure filtration performance under varying airflow conditions. The filter also comes in either box style or peripheral header configurations.
