China's air purifier industry has developed rapidly due to severe smog weather in recent years. The air purifier has been pushed to the fifth home appliance after TV, refrigerator, washing machine and air conditioner. But now the country is vigorously rectifying the environment, the haze gradually subsides. , Do we still need to buy an air purifier?
I want to ask why not?
There is no smog under the sky, it is something to celebrate, but it does not mean that our indoor air environment is better than outdoor, and we are making haze, harmful gases. For example, CO2 produced by fuel combustion, (CO), (SO2 2. Second-hand smoke has more than 4,000 harmful chemicals and dozens of carcinogens.
Perhaps in the face of a home environment that you think is clean, you may not think that your indoor air is unclean and safe. In fact, there are more than 900 types of indoor air pollutants, which are mainly divided into three categories:
(1) Gas pollutants. Main sources of home improvement building furniture materials, fuel burning, cooking, secondhand smoke
(2) Microbial contaminants. Such as allergic reactants, viruses, fungi and microorganisms that are easy to breed indoors.
(3) Respirable particulate matter (PM10 and PM2.5). Source outdoor, fuel burning, cooking, secondhand smoke.
Nowadays, many people spend 80% of their lives indoors. 68% of human diseases in humans are related to indoor air pollution, most of which are related to indoor biological pollution. Recently, the European Court of Auditors reported that the EU has more than one thousand daily. People die prematurely because of air pollution. There are about 2.1 million children who die from upper respiratory tract infections caused by decoration pollution every year. The death of more than one million children under the age of five is related to indoor air pollution. Health care disease prevention and treatment investigation.
When it comes to decoration pollution, everyone must be familiar with formaldehyde. Recently, relevant online media have been reporting that the formaldehyde in the rental room is too high. It can be said that it is a one-stop move. The China Consumers Association and Zhejiang Consumers Association respectively voted for Beijing 30 in 2017. The indoor air conditions of the households and the 53 households in Hangzhou were tested. After testing, the harmful gases and radioactive pollution in the living room were different. The formaldehyde concentration in the living room exceeded the standard by more than 70%, and the highest exceeded the standard by more than 10 times. Other volatile organic compounds TVOC and benzene exceeded the standard is also very serious.
Formaldehyde, benzene, volatile organic compounds (TVOC) are toxic, irritating, carcinogenic chemical gases, commonly found in building decoration materials, coatings, artificial boards, artificial leather, automotive interiors.
In the face of this situation, the air purifier plays a very good role. Perhaps we no longer need a defogging air purifier, but the air purifier, as long as it is right, is not useless.
A comprehensive purifying and high-performance air purifier capable of adsorbing, decomposing or converting various air pollutants (generally including PM2.5, dust, pollen, odor, decoration pollution such as formaldehyde, bacteria, allergens, etc.), Keep indoor or indoor air in a healthy and stable state. Effectively help patients with respiratory diseases, allergic people reduce respiratory irritation to alleviate allergic symptoms.
As for what kind of air purifier to choose, it is decided according to the indoor air pollution situation.
