Air purifier is a must-have item in foggy days! In foggy days, many homes have purifiers on every day to prevent smog. But some people are confused. Can an air purifier remove fog and haze? About, is it useful to open an air purifier in smog? Can an air purifier remove fog and haze? Let me answer them for you one by one!

Can an air purifier remove fog and haze?

In April, 20 15, Tsinghua University released the report on data analysis of indoor air quality survey, saying that modern people spend 80% of their time indoors, and the per capita indoor PM2.5 intake is four times that of outdoor. Zhao Bin, a professor at the School of Architecture of Tsinghua University, said that even if the doors and windows were completely closed in foggy days, the indoor PM2.5 concentration would be at least 1/3 outdoor if no purification measures were taken. It is necessary to use air purifier correctly, which can improve indoor air quality.

Is the smog purifier useful?

Generally speaking, particulate matter is the most polluted indoor air, and the adsorption and filtration effect of air purifier on particulate matter is excellent. Basically, the air purifier can filter 100% of particulate matter. This shows that the air purifier still has a certain role in foggy days.

Can the purifier filter pm2.5?

Li, a researcher at Jilin Academy of Social Sciences, holds a negative attitude towards this. He said that the existing air purifiers have basically no effect on PM2.5, and only the extremely advanced ones are truly effective. Even if it can be filtered out, it is only in a small area, and the whole house cannot be filtered out. You can't listen to what the salesman says. Salespeople sometimes exaggerate things to promote products.

Experts say that ozone itself is a pollutant, and the principle of adsorption materials is the same as that of drinking water purifiers. Adsorption materials must be replaced frequently, otherwise they will be released as pollution sources. Liu Jingsheng, deputy director of the Center for Virus Prevention and Control of Hebei Provincial Center for Disease Control and Prevention, believes that consumers who simply buy purifiers for smog weather are not so much buying health as buying peace of mind. In fact, in addition to extreme haze weather, window ventilation is more effective than opening a machine.
