With the gradual cooling of the weather, the haze weather in the province also followed. During this period, the masks we wear are KN95 masks. It is the most ideal because KN95 masks themselves have high filtering and protection performance. This also makes it the first choice for public protective masks. On the one hand, it not only protects the haze, but also protects itself on the other. Each type of mask is based on its different standards to provide people with a corresponding level of protection.
Some areas in the country have already started to snow. As the haze weather gradually hits, most people consciously wear anti-haze masks when they go out. However, experts say that ordinary cotton gauze masks and medical masks that we usually see most often have no blocking effect on PM2.5 in the air. Only professional protective masks have a protective effect against smog.
Of course, masks only play an auxiliary role, and our own protection measures cannot be ignored. Usually it is best not to exercise for a long time outdoors, you can try some yoga exercises at home. If you must go outdoors, please remember to wear a mask when you go out.
What kind of mask should I wear on a hazy day?
1. Gauze mask: Although it can filter out most dust or germs, it has little protective effect on blocking PM2.5.
2. Activated carbon mask: Activated carbon mask is added with an activated carbon layer with adsorption effect, but it only works to isolate peculiar smell, and the effect of haze prevention is still not good.
3. Ordinary disposable medical masks: under normal circumstances, they are made of non-woven fabrics, which can prevent droplets and absorb moisture, but the effect of filtering particles is not ideal.
4. KN95 mask:
The biggest feature of the KN95 mask is that it can prevent droplet infection caused by the patient's body fluid or blood splash.
Although KN95 masks are ideal, they are not suitable for everyone!
The function of KN95 mask: anti-dust particles. Because KN95 masks are professional protection level masks, if we wear this type of mask when we go out, it will be of great help to our own protection. This type of mask is a professional dust mask. Choose it in haze weather. Masks, we need to first consider the type of particulate matter. The suspended particulate matter in haze weather is mainly non-oily particulate matter. It is generally recommended to choose a KN95 mask with a filtration efficiency of more than 95% for PM2.5. However, this type of mask may not breathe as smoothly as other masks, so it is not recommended to wear it for a long time.
All in all, everyone can choose according to the daily air quality index. If the air quality is better, then you can choose ordinary disposable masks; but if the air quality is poor, it is best to choose professional protection such as N95 masks for anti-smog Masks.
