Can disposable masks prevent smog? The answer is no. Disposable masks cannot protect against smog. In the fog and haze, masks have become a must for many people, but disposable masks not only can not achieve the protective effect of anti-fog masks from the perspective of protection level, mask material and wearing method.
We often see many people go out with disposable masks on a foggy day, but can such disposable masks really prevent smog? Disposable medical masks can basically only block coarse particles, and have very limited blocking effect on fine particles such as bacteria and PM2.5. Relatively speaking, the thicker the layer of gauze mask, such as increasing the thickness to 8 or even 12, the blocking effect may be better.
A disposable mask is not enough to resist the lethality of smog, so it can not effectively prevent smog. Moreover, the disposable mask should not be used multiple times and worn for a long time. These improper wearing methods will accelerate the production of bacteria in the mask and may cause respiratory diseases.
and labor insurance network technical recommendations, wearing masks have certain knowledge, wearing masks is definitely stronger than not wearing, but wearing is not all right. Just like the most common one-time disposable masks that we usually wear in a hazy sky, it is equivalent to not wearing them. When choosing a mask, it is best to choose a mask with good material and high density, and pay attention to the way of wearing. Be sure to wear it strictly, cover the respiratory tract, and pay attention to frequent replacement.
At the same time, when choosing these anti-fog masks, don’t blindly believe in the manufacturer’s slogan, or choose according to product quality standards. Ordinary dust masks and disposable masks are not very effective in preventing smog. Professional standard anti-fog masks also need to be fitted to the human face in order to exert the anti-fog effect. Therefore, anti-fog masks also have a certain effect, but you need to pay attention when choosing to wear them.
