Is the air purifier a necessity?

According to the survey, indoor air pollution is extremely harmful to the human body, especially pregnant women. Indoor air pollution can cause fetal malformations, leading to various blood and respiratory diseases in infants and young children. Health authorities in Europe and the United States point out that more than 1 million people die each year from chronic obstructive pulmonary disease due to indoor air pollution. According to the World Health Organization (WHO), the number of air pollution deaths per year has reached 6.5 million, and the total loss of life caused by indoor air pollution has reached 139 million years. It would be terrible if we breathe dirty air every day.
There are three common types of indoor air pollutants:
(1) O3, CO, CO2, NOx and radioactive element lanthanum (Rn) and its daughters. Especially when the indoor ventilation conditions are poor, these gas pollutants will accumulate indoors, the concentration will increase, and some concentrations may exceed the hygienic standard several times, causing serious indoor air pollution.
(2) Microbial contaminants. Such as allergic reactions in the room, viruses, fungi and microorganisms.
(3) Respirable particulate matter (PM10 and PM2.5). In addition to PM2.5, harmful gases such as formaldehyde and benzene are another killer of indoor air pollution.
At this time, in the summer, when people turn on the air conditioner, the doors and windows are closed, and a large amount of harmful gases such as fluorine remain in the air, posing a great threat to the health of the child.

What are the functions of the air purifier?

Dust removal:The biggest function of the air purifier is to remove dust, including dust, dust, pollen and so on. For those who are sensitive to the nasal cavity, an empty purifier is a very necessary device.

Sterilization: Sterilization is an important function of negative ion purifiers. The air purifier with negative ion function can effectively remove indoor bacteria and no indoor pollution to decompose residues. The decomposition products of formaldehyde, toluene and other pollutants are non-toxic and tasteless carbon dioxide and water, which are safe and effective.
Net taste: Households who use air purifiers, especially those who choose negative ion air purifiers, often report that the smoke in the room dissipates after the air purifier is turned on. Decorative odors, such as some of the taste of the board, can also be purified.
Health care: At present, high-end air purifiers can release high-activity air negative ions, which can not only provide clean air, but also provide healthy air vitamins rich in air, while optimizing the air to provide the body with the effect of air vitamin health care.

Therefore, it is necessary to purchase an air purifier for the family. The Homgeek 3500SQ.FT air purifier has three filters from the bottom to the top and top, and the air intercepts the hair through the pretreatment net. Large suspended solids, such as fine particles; PM-2, PM0.3 and pollen and other particulate matter harmful to the human body through HEPA filters; finally, harmful gases such as formaldehyde, benzene and fluorine are effectively removed by a deodorizing filter.With this air purifier, you can breathe fresh air without worrying about indoor air pollution.
