The main amendments are as follows.

Amendments of the inspection standard

The following provisions were added into the inspection standard of air purifiers (rated voltage lower than 250V).

The energy efficiency (SASR/W [Dust]) and power consumption in standby mode, which are tested according to the national standard of Republic of China-“Household and similar air purifier-performance test method”, have to meet the related provisions of “Minimum energy performance standards for air purifiers”.


On June 11,2021, the Bureau of Energy, Ministry of Economic affairs of Taiwan officially announced the “Labeling items, labeling methods and inspection methods for the minimum energy performance standards and energy efficiency grades of air purifiers”, and the announcement will come into effect on January 1, 2023. The minimum energy performance standards stipulated by the announcement are as follows.

Energy efficiency CASR/W (Dust) (cmm/W)

Power consumption in standby mode


Product with wireless network connection function: ≦1.00W

Product without wireless network connection function: ≦2.00W

※The measured value should not lower than the above standard value, and be higher than 95% of the labeled value. ※The labeled value and measured value have to lower than the above standard value, and the measured value should lower than the labeled value.
