Air purifier produces 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. Persistent inhalation of smoke from kitchen fires kills more people each year than 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. Chinese and American scientists who participated in the study 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 in their homes. 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.
