In this standard, the energy efficiency of air purifiers is classified according to the measured energy efficiency ratio, gaseous pollutant purification efficiency and standby power of the product. The energy efficiency level is divided into three levels, among which level 1 has the highest energy efficiency. At the same time, corresponding technical requirements are put forward for standby power.
