Air purifiers, also known as "air cleaners", air purifiers, purifiers, are capable of adsorbing, decomposing or converting various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde, etc.). , bacteria, allergens, etc., products that effectively improve air cleanliness, mainly divided into household, commercial, industrial, and building.
There are many different technologies and media in the air purifier that enable it to provide clean and safe air to the user. Commonly used air purification technologies include: adsorption technology, negative (positive) ion technology, catalytic technology, photocatalytic technology, superstructure photomineralization technology, HEPA high efficiency filtration technology, electrostatic dust collection technology, etc.; material technology mainly includes: photocatalyst, activated carbon, Synthetic fiber, HEAP high efficiency material, negative ion generator, etc. The existing air purifiers are mostly compounded, that is, a plurality of purification technologies and material media are simultaneously used.
According to a WHO study, among the 4.3 million people worldwide who died from kitchen air pollution in 2012, 34% suffered from stroke, and 22% and 26% of chronic obstructive pulmonary disease and ischemic heart disease, respectively. About 6% of lung cancer.
In a research project on disease risk assessment in the famous British medical journal Lancet, kitchen air pollution (smoke) has been listed as the biggest health hazard after high blood pressure, smoking and alcohol abuse. The number of deaths per year from continuous inhalation of smoke from kitchen fires is greater than the total number of deaths from malaria, tuberculosis and AIDS.
The study of Chinese farmers in the Journal of the National Cancer Society in the United States also confirms 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 who had no ventilation in their homes had twice the probability of developing lung cancer, about twice as many farmers who built chimneys or ventilation at home. Researchers say that the use of stoves without ventilation is similar to smoking in the extent of lung cancer.
Air purifiers are also known as products that can adsorb, decompose or convert various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde and other decoration pollution, bacteria, allergens, etc.) to effectively improve air cleanliness. Mainly used in household, commercial, industrial and building.
