The smog is like a prodigal son, and an air purifier captures the prodigal son's heart?

　　Smog is caused by the increase of suspended particulate matter in the air, the growth of urban population, industrial development, the rapid increase of motor vehicles, pollutant emissions and a large increase in suspended solids. In the end, it is our own product. And its existence is not timed. It is possible that the haze is still heavy today, and it will be gone with the wind tomorrow. This also confirms that it is as bohemian as a prodigal son. And why can air purifiers capture the hearts of prodigal sons? Because the haze is dispersed. In the face of scattered haze, the air purifier can remove it very well.

　　Why is the smog like a prodigal son?

　　The prodigal son should be in our hearts the kind of bohemian people who are not bound by conventions and moral codes, and according to the current situation, the smog is very similar to its definition. But the prodigal son, although unruly, will not cause any harm to society. The smog does cause serious harm to the human body. The reason for this idea is to read an article "Ten Xie Smog". It is possible to understand that the arrival of smog may not be a bad thing, because its existence also officially reminds us of the importance of caring for the ecological environment. Therefore, it is most appropriate to compare the smog to a prodigal son.

　　And why can air purifiers capture the hearts of prodigal sons?

　　As for why we can capture the prodigal son's heart, we need to divide it into two steps. First, we need to know what the smog is made of. And can air purifiers remove smog?

　　1. What is smog made of?

　　Smog is a combination of fog and haze.

　　Fog is an aerosol system composed of large numbers of tiny water droplets or ice crystals suspended in the air near the ground.

　　Haze is composed of particles such as dust, sulfuric acid, nitric acid, and organic hydrocarbons in the air.

　　Smog weather is a state of air pollution. Smog is a general expression for the excessive content of various suspended particulates in the atmosphere, especially PM2.5 (particles with aerodynamic equivalent diameter less than or equal to 2.5 microns) are considered to cause haze. The "culprit" of the weather.

　　2. Can an air purifier remove smog?

　　At present, the purification technology of air purifiers on the market mainly adopts the physical filtration technology of HEPA filter and activated carbon filter. The HEPA filter is mainly used to filter and purify the particulate matter PM2.5, dust and other solid pollutants in the haze, while the activated carbon filter is mainly to adsorb and remove toxic and harmful gases such as sulfur dioxide and nitrogen oxides in the haze, and can also absorb indoor decoration. formaldehyde, odor and other volatile gases.

　　Air purifiers can remove haze mainly by HEPA filters and activated carbon filters. On the market, different air purifier manufacturers and brands use different filter grades, and filters with poor quality cannot remove particulate matter. Filtered. Some low-end air purifier products only use HEPA filters instead of activated carbon filters, which cannot completely remove haze to a certain extent.
