ASHRAE 52.2 is a method of testing general ventilation air cleaning devices to determine their removal efficiency as a function of particle size. It is a method that determines the ability of an air filter to remove particles on the basis of specific particle sizes ranging between 0.3 to 10 microns. A central feature of ASHRAE 52.2 is the incorporation of the Minimum Efficient Reporting Value (MERV) for each filter tested. Angela Southey is the head of the environmental test chamber at airmid healthgroup. In this interview, we ask Angela about Airmid’s new ASHRAE 52.2 test duct, its functional association with the Environmental Test Chamber and the importance this facility has for HVAC testing, MERV testing and its potential for contract research.
