Many test methods exist for evaluating gaseous-contaminant filtration media, and a few for evaluating functional filters and other devices. These test methods are designed primarily for use in product quality control and to rank products. Designers of filtration devices and HVAC (Heating, Ventilating and Air-Conditioning) systems engineers, however, need test data that allows calculation of device performance under actual operating conditions. End users need data to determine system maintenance costs. We call such tests design parameter tests.
