WHO reports that 34% of 430 thousands of people WHO died globally due to kitchen air pollution in 2012 suffered from stroke, 22% and 26% of chronic obstructive pulmonary disease and ischemic heart disease, respectively, and about 6% died from lung cancer. In a study on disease risk assessment in the uk famous medical journal "lancets", kitchen air pollution (smoke) has been listed as the greatest health risk after hypertension, smoking and alcohol abuse. More deaths occur each year from the continuous inhalation of smoke generated by kitchen fires than the total number of deaths due to malaria, tuberculosis and aids. The study of farmers in China in the journal of national cancer society of America is also testified on the influence of kitchen air pollution on human health. Scientists in China and America who participated in the study investigated more than twenty thousand farmers in Yunnan province and found that farmers with home stoves without ventilation had about twice as many chances as farmers who built a chimney or ventilation at home. Researchers have shown that to the extent that lung cancer is a result, stoves without ventilation are used as much as smoking. The air purifier is also called as a product capable of adsorbing, decomposing or converting air pollutants and effectively improving air cleanliness, and is mainly applied to household, commercial, industrial and building.
