Cloudy, in order to prevent PM2.5 particulate matter health hazards, many people often wear masks to travel abroad. However, people tend to concentrate on neglecting outdoor and indoor pollution. According to statistics, the biggest victims of indoor pollution are children, pregnant women, the elderly and patients with chronic diseases, especially children, who are more vulnerable to indoor pollution than adults. An air purifier is the first choice for many civilians to clean indoor air and protect the health of their families.

The operation of the domestic standard air purifier Rixin on March 1 this year will ensure that consumers choose the right air purifier, but one of the parameters is not yet fully clear. The following are the most common CADR values.

CADR (Clean Air Delivery Rate) is the abbreviation of the American Association of Consumer Electronics Manufacturers (AHAM) according to the strict test standards of air purifier testing and is the clean air output ratio. For more regulatory and regulatory test conditions than the new national standard air purifier under rated conditions, please refer to its purification capacity parameters. The two target pollutants include particulate matter and gaseous pollutants. Representing an air purifier means providing a relatively clean air rate and being able to clean cubic meters per hour to prove that the air purifier’s higher purifying performance is very good.

The performance and quality of air purifier mainly depend on the net airpower ratio (CADR value), the net airpower ratio, and the purifying efficiency of the purifier is higher. However, with the purchase of air purifiers, users should not be aware of the pursuit of high value, CADR values are not better based on the environmental areas they measure. When a user chooses a higher CADR which is worth using in a room of only 20 square meters, it often causes unnecessary waste and the air purifier can not even achieve the best effect.
