How should room air cleaners be sampled for verification testing? Follow

All room air cleaners are understood to have been qualified based on a single test, so verification should also be based on a single test. A single unit should be tested as described in the current ENERGY STAR specification and all referenced test methods. However, for either qualification or verification testing, manufacturers have the option, as specified in the specification, of testing the unit once or testing three times with different filters and averaging the result.
