First, product use

The device is mainly used to assess the ability of household (vehicle) air purifiers to remove particulate matter, gaseous pollutants, microorganisms and other pollutants in the ambient air. The environmental test chamber can realistically simulate the polluted indoor environment, and can evaluate and test the air purifier's clean air volume (CARD), cumulative purification (CCM), purification energy efficiency, applicable area and purification life parameters.

Second, the implementation of standards

GB/T 18801-2014 "Air Purifier" (Draft for Comment)

Third, technical indicators
