How is the energy efficiency of air purifiers assessed?

Air purifiers are used in the home, medical and industrial fields, and the home field is dominated by the single-unit type of home air purifiers as the mainstream products in the market. The most important function is to remove particles in the air, including allergens, indoor PM2.5, etc., but also to solve the problem of volatile organic compounds air pollution indoors, underground space, and inside the car due to decoration or other reasons. Since the release of air pollutants in relatively enclosed spaces is characterized by persistence and uncertainty, the use of air purifiers to purify indoor air is one of the internationally recognized methods to improve indoor air quality.

Energy efficiency ratio of 3.40 or more: energy efficiency class 1.

Energy efficiency ratio 3.20~3.39: energy efficiency class 2.

Energy efficiency ratio 3.00~3.19: energy efficiency class 3.

Energy efficiency ratio 2.80~2.99: energy efficiency class 4.

Energy efficiency ratio 2.50~2.79: energy efficiency class 5.
