摘要：This paper demonstrates the background and the significance on the national standard research on the minimum allowable values of energy efficiency and energy efficiency grades for air cleaners. The study also introduces the general thinking and principle of the standard development the determination of the minimum allowable values of energy efficiency, the classification of the energy efficiency grades for air cleaners, as well as the testing methods, which would help to eliminate the production of the high energy consumption air cleaner products, and effectively improve their level of the energy efficiency through the developing and implementation of the national standard.
