[0002] Air filtration is an important technical process that removes impurities and pollutants from the air through a series of physical and chemical methods, thereby providing us with a clean and healthy indoor environment. With people's increasing attention to environmental quality, air filtration technology has been widely used in various fields. Air filtration devices are important equipment for maintaining indoor air quality. If they cannot be cleaned quickly, a series of problems may occur.

[0003] Failure to clean the air filter quickly will result in a decrease in filtering effect. As the use time increases, the filter will gradually accumulate dust, particulate matter and other pollutants, which will clog the pores of the filter and reduce its filtering efficiency. If it is not cleaned in time, the filter will not be able to effectively remove pollutants in the air, thus affecting the indoor air quality.
