Is the foggy air purifier really useful?
Air purifier classification Air purifier, also known as "air cleaner", air freshener, refers to the ability to adsorb, decompose or convert various air pollutants (generally including dust, pollen, odor, formaldehyde and other decoration pollution, bacteria, allergens, etc.) Products that effectively improve air cleanliness are currently dominated by household and commercial air purifiers that remove indoor air pollution. According to the purification needs, the air purifier can be divided into: (1) Purified type. If you are located in a moderately humid area, or if the air quality requirements are not too high, then you can purchase a pure air purifier to meet your needs. (2) Humidification purification type. If it is located in a drier area, the air conditioner is often air-conditioned and dehumidified, resulting in indoor air drying, or high air quality requirements, then choose an air purifier with humidification purification function, it will be the most suitable choice. . (3) Intelligent type. If you like automation, intelligent monitoring of air quality, or a noble taste, or a more decent gift, you can choose the smart air purifier is the best choice. (4) Vehicle type. If it is used for air purification in a car, it needs to purify the car's odor, car formaldehyde and other car pollution, and can be placed in the car's air purifier, so the best choice is the car-type air purifier. (5) Desktop type. That is, it is placed on the tabletop to purify a certain range of air around the tabletop, and to protect the health of the person near the tabletop. If you often sit in front of a computer, at a desk, or at a desk, but the indoor area is not small, or in a public place, it is not cost-effective to buy a large air purifier. Type air purifiers are a good choice. (6) Large and medium-sized. Mainly used in large indoor areas, such as home halls, senior bank offices, senior executive offices, important lecture halls, high-end hotels, hospitals, beauty salons, kindergartens and other occasions. (7) Central air conditioning system type. It is mainly suitable for the case where a central air conditioner or a single room with a ceiling or multiple rooms are cleaned together. Can an air purifier really filter out pollutants? Open the machine and open the window, which one is healthier? Can thousands of air purifiers on the market really achieve the magical effect of filtering pm2.5? Li Xiaoqun, a researcher at the Jilin Provincial Academy of Social Sciences, has a negative attitude. Li Xiaoqun: The existing air purifier basically does not work for PM2.5, and the only one that is really effective is extremely advanced. Even if it can be filtered out, it is only in a small scope. The whole house cannot be filtered out. It cannot be heard by the salesperson. Sometimes the salesperson exaggerates things in order to sell things out. In theory, the current air purification products on the market can be basically divided into two categories, one is based on a variety of adsorption materials, such as activated carbon, photocatalysts to absorb harmful substances. The other type uses plasma discharge technology, which produces ozone and decomposes pollutants in the air. Experts say that ozone itself is a kind of pollutant, and the principle of adsorbing materials is the same as that of drinking water purifiers. It must be changed frequently to adsorb materials, otherwise it will be released as a source of pollution. Liu Jingsheng, deputy director of the Center for Disease Control and Prevention of Hebei Provincial Center for Disease Control, believes that consumers who purchase purifiers solely for the sake of smog are not so much as buying health. In fact, in addition to extreme smog weather, window ventilation is still more effective than opening the machine. Liu Jingsheng: Actually, this smoggy weather doesn't really make much sense. It is probably a psychological effect. If we prevent respiratory infections, indoors should be ventilated every day at the appropriate time. The best time period should be around 10 am and 3 pm. During these two periods, you can open the window for about 20 minutes. that's it. Do not open the window, expect the air purifier to purify the air inside your home is particularly fresh, it can only purify, can not guarantee sterility, no virus, it can not play this role. It is not necessary for our people to buy an air purifier because of this smoggy weather.
