Air purifiers don't need to be blindly selected according to national standards.Home air purifier Pr

　　The Environmental Development Center of the Ministry of Environmental Protection issued my country's first air purifier Chinese environmental label standard on the 13th. The standard is based on the "Air Purifier" (GB/T18801-2015) national quality standard, but the regulations are more stringent.

　　According to the standard, the air purifier's purification energy efficiency for removing fine particulate matter (PM2.5) is not less than 5 cubic meters per watt hour; the purification energy efficiency for removing formaldehyde or toluene is not less than 1 cubic meter per watt hour; the standard will be It will be implemented on January 1 next year.

　　What is this concept?

　　Purification energy efficiency refers to the amount of clean air that an air purifier can produce per unit of power consumption, in cubic meters of watts per hour.

　　The National Household Appliances Quality Supervision and Inspection Center once introduced that the national standard GB/T18801-2015 divides the purification energy efficiency into high-efficiency and qualified levels. Purification energy efficiency evaluates the performance of purifiers more comprehensively than CADR, making purifiers of different grades comparable.

　　In general, the larger the value of purification energy efficiency, the cleaner is energy-saving and the purification effect is better, and it is the product of choice for consumers.

　　Take a look at an experimental data!

　　From September to November, the staff of the China Consumers Association purchased 24 types of air purifiers from home appliance stores, large department stores, direct sales stores, etc. as ordinary consumers. The samples involved 16 indoor air purifier brand products, and the unit price was purchased. It ranges from RMB 11,111 to RMB 999 per unit. Regarding the main performance of air purification that consumers care about, the China Consumers Association commissioned the China Home Appliance Testing Institute to test and compare these products.

　　The comparison test results show:

　　The maximum value of the particulate matter purification energy efficiency of the prototype of the air purifier manufacturer is 12.950 (w·h), and the lowest value is 2.509 (w·h), a difference of 4 times.

　　Among the samples that claim to have the function of removing formaldehyde, the highest value of formaldehyde purification energy efficiency is 5.143 (w·h) and the lowest is 0.833 (w·h), a difference of 5 times.

　　Therefore, everyone must keep their eyes open when choosing!
