Experts advise: air purifiers are not as functional as possible

Recently, many places have experienced severe haze, and air purifiers have become the focus of consumers’ attention. Experts advise that the best affordable air purifier for smoke is not as functional as possible.

Recently, reporters learned in-home appliance stores and some online shopping malls that many brands of best air purifier affordable claim to have functions such as formaldehyde removal and humidification. Some clerk of home appliance store told reporters that the humidification function is very helpful for air purification, and water vapor can help absorb harmful substances in the air.

Liu Zhang, an associate professor at the School of Environmental Engineering and Science at Peking University, said that the choice of an air purifier depends on the basic functions marked by the purifier itself, and there is no need to choose a product that has been versatile. For example, during the sputum pollution in Beijing, it is mainly contaminated by fine particles and contaminated with organic matter. Therefore, when selecting an air purifier, as long as the purifier achieves the indicators of pollutants (fine particles and organic matter) and fresh air volume, can.

Liu Zhaorong said that the functions of temperature and humidity adjustment are to meet physical comfort. There is no experimental data indicating that it has sufficient correlation with air purification. Liu Wei, the attending physician of the Department of Respiratory Medicine of the First Hospital of Jilin University, said that if the air purifier with humidification function is not properly operated, it will easily breed bacteria in the water and affect the health of the body.
