PM2.5
PM2.5 has an important impact on air quality and visibility. Compared with the coarser atmospheric particulate matter, PM2.5 has a small particle size, large area, strong activity, easy to carry heavy metals, microorganisms and other harmful substances, and has a long residence time in the atmosphere and a long transportation distance, which is harmful to the quality of the atmospheric environment and the human body. There is a certain threat to health. PM2.5 is not only available outdoors, but also indoors. Ninety percent of indoor PM2.5 comes from smoking, and the cooking fume produced by cooking will also aggravate the indoor concentration of PM2.5. Due to the particulate matter produced by smoking and cooking oil fume, long-term exposure may cause damage to the human respiratory tract.Formaldehyde
Formaldehyde is a colorless irritant gas, which has irritating effects on human eyes and nose. At present, formaldehyde has been listed as a “known human carcinogen”. The biggest factor that causes excessive formaldehyde in the indoor environment is home improvement building materials. In home improvement building materials, formaldehyde hides in various glues and coatings in wall paint, floor, and furniture. Formaldehyde can cause tension, dizziness, headaches and other hazards to the nervous system. It can also damage the respiratory tract, digestive tract, circulatory system and nervous system to varying degrees. Long-term living in a house with excessive formaldehyde may cause serious consequences.

Indoor dust, shedding hair, pet dander, indoor odor, bacteria and viruses and other indoor pollution particles can easily pass through the human hair filter and blood barrier, causing discomfort and disease to humans. Diseases such as allergic asthma, family colds, and other respiratory infections may be closely related to the poor quality of indoor air. Indoor air pollution seriously affects our health every day.Air purifier mainly uses a fan to draw air into the machine, and then filters the air through a built-in filter, which can filter dust, odor, and disinfect. Generally speaking, air purifiers are suitable for newly renovated or renovated homes, homes with asthma or pets, hotels and hospitals and other public places.
