On May 20, 2020, the Technical Requirements and Experimental Methods for Performance of High-Efficiency Air Purifiers which was formulated by China Association for Standardization (CAS) and China Household Electric Appliance Research Institute (CHEARI) passed the review. The standard was led by Jingdong (JD) Household Appliances, jointly compiled by Philips, Blueair, Panasonic, IAM, Sharp, IQAir, 352, Huawei, A.O. Smith, etc. The new association standards have set a higher efficiency requirement than the relevant national standard and have detailed technical requirements for the purification of fine particles under 0.3 μm, sterilization, intelligent modes, air purity sensors and other aspects. They will become important reference standards for high-efficiency air purifiers after COVID-19. It is helpful for the air purification industry to meet the current market demand in time and satisfy the needs of more families to prevent the virus.

The current national standard of air purifier pays more attention to the purification effect and parameters of PM2.5 and chemical pollutants. Due to the outbreak of COVID-19, the purification effect of fine-particle aerosols to which the virus attaches to has become the focus of consumers when purchasing air purifier products. Currently, there is no national standard for air purifiers that can deal with fine particles under 0.3 μm, therefore, the new standard is mainly to help consumers understand and choose the right high-efficiency air purifier.

 

The new standard improved the Technical Requirements and Testing Methods for Performance of High-Efficiency Air Purifiers, puts forward technical requirements and testing methods for air purifier products in terms of fine-particle aerosol clean air delivery rate (CADR), intelligent modes, and air quality sensors. It also puts forward higher evaluation requirements for CADR, bacterial elimination rate, purification efficiency, noise, harmful substances, etc. For example, the measured value of fine-particle aerosol CADR should not be less than 100 m3/h; the measured value of Cumulate Clean Mass (CCM) of particles should not be less than 12,000mg; the measured value of CCM of gaseous pollutants (formaldehyde) should not be less than 1500mg; if the purifier has the sterilization function, the sterilization rate should not be less than 99%.
