Air purifiers, also known as "air cleaners", air purifiers, and purifiers, refer to decoration pollution that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde, etc. , bacteria, allergens, etc.), products that effectively improve air cleanliness, are mainly divided into household, commercial, industrial, and building.

There are many different technologies and media in air purifiers that enable it to provide clean and safe air to users. Commonly used air purification technologies include: adsorption technology, negative (positive) ion technology, catalytic technology, photocatalyst technology, superstructured photomineralization technology, HEPA high-efficiency filtration technology, electrostatic dust collection technology, etc.; material technologies mainly include: photocatalyst, activated carbon, Synthetic fibers, HEPA high-efficiency materials, negative ion generators, etc. Most of the existing air purifiers are composite types, that is, a variety of purification technologies and material media are used at the same time.

Background:

According to a WHO research report, in 2012, among the 4.3 million people who died due to kitchen air pollution, 34% suffered from stroke, 22% from chronic obstructive pulmonary disease and 26% from ischemic heart disease, and 26% of the deaths. Lung cancer accounts for about 6%.

In a research project on disease risk assessment in the famous British medical journal The Lancet, kitchen air pollution (smog) has been listed as the biggest health risk after high blood pressure, smoking and alcoholism. More people die each year from persistent inhalation of smoke from kitchen fires than from malaria, tuberculosis and AIDS combined.

A study on Chinese farmers in the "Journal of the National Cancer Society" in the United States also confirmed the impact of kitchen air pollution on human health. Participating Chinese and American scientists surveyed more than 20,000 farmers in Yunnan province and found that farmers whose stoves were not ventilated at home were about twice as likely to develop lung cancer as those who built chimneys or ventilation at home. Using an unventilated stovetop is about the same as smoking in terms of causing lung cancer, the researchers said.

Air purifiers are also known as products that can absorb, decompose or convert various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde and other decoration pollution, bacteria, allergens, etc.), and effectively improve air cleanliness. , mainly used in household, commercial, industrial, building.
