New standards set for air purifiers

A new national standard for air purifiers is set to be unveiled by authorities on Friday to bring order to the country's chaotic purifier market.

The draft national standard, which will be made available for public comment, will include more specific metrics for measuring the performance of air purifiers, including their "clean air delivery rate", or the number of cubic units of air per minute delivered with all particles of a given size removed, the Standardization Administration said in a statement on Thursday.

The country's widespread air pollution problem has given rise to a booming market in air purifiers, with total sales volume reaching 2.4 million units in 2013, Nanfang Daily reported.
