In closed and semi-enclosed spaces, the release of air pollution pollutants is characterized by persistence and uncertainty. The main pollutants include formaldehyde, bacteria, viruses, dust mites, particles, pollen, etc. Evidence shows that these pollution The harm of pollutants to the human body is much higher than the harm of air pollution to the human body. Indoor pollutants mainly come from cigarettes, renovation projects, pets, cooking, garbage and human bodies. Therefore, the treatment of indoor pollution has always been an important challenge in the fields of home appliances and medical care.

In order to purify the indoor air and effectively improve the cleanliness of the indoor air, an air purifier with the function of purifying the air has emerged as the times require.
