Airguard's Research and Technical Center is the nation’s largest manufacturer-based laboratory for air filter testing. The lab provides testing and data analysis on filters and filter media for particulate and gaseous contaminants. The backbone of the Tech Center is the ASHRAE 52.1 and 52.2 test ducts. ASHRAE 52.1 tests quantify air flow resistance, arrestance, atmospheric dust spot efficiency, and dust holding capacity. ASHRAE Standard 52.2 measures particle size efficiency. This newer standard quantifies filtration efficiency on different particle size ranges for clean and incrementally loaded filters. The standard rates particle size efficiency results as a MERV Rating between 1 and 20. Airguard continually tests new medias and filter designs to enhance our air filter product line, which includes over 10,000 filtration products, for commercial, industrial, institutional and cleanroom environments, and for special applications such as gas turbine intake and paint overspray.
