Can the filter screen of the air purifier be cleaned

　　The air purifier has been used for a long time, and the filter screen is easy to be stained with all kinds of dust. Can the filter screen of the air purifier be cleaned?

　　The filter screen of the air purifier cannot be cleaned. If there are too many impurities attached to it, you can choose to replace the filter screen. The filter screen cannot be cleaned because of its special material, which is easy to be damaged in the cleaning process, resulting in the use of filtration effect. Compared with the filter screen, some filter elements can't be cleaned. They can only be treated by simple dust removal and replaced after a period of use, so as to ensure the purification efficiency and avoid re pollution.

　　Since the filter screen of the air purifier uses activated carbon, it is unnecessary to take out the activated carbon and wipe the dust with a clean rag to expose it to the sun. And the general air purifier is divided into several ways of filtration. In a word, the air purifier now adopts the triple filter screen of pre filter screen, HEPA filter screen and activated carbon filter screen as the mainstream configuration. Each layer of filter screen has different functions and configurations, and the cleaning and maintenance methods are also different.
