Can disposable medical mask filter haze ?

There are many factors that affect our living environment. Now this season is not far away from winter. Many places are slowly showing haze weather, haze has brought great threat to people's body, so many users will wear masks to block when they travel. But many users will ask whether medical masks can filter haze. Here is a brief introduction for the majority of users, hoping to help us.

The utility model relates to a disposable Medical Mask, which comprises a common medical mask, a medical surgical mask and a medical protective mask, and the protection level of the disposable medical mask is high. The machine is made of three layers of materials, the inner layer is non-woven fabric, the middle layer is ultra-fine polypropylene fiber melt blown material layer, and the outer layer is non-woven fabric or ultra-thin polypropylene melt blown material; The filtering power of Liming hydraulic filter is more than 95%.

Although the filter function of this mask is very good, it can't filter completely. Haze not only contains non oily particles, such as dust, acid mist, coal dust, cement dust, microorganisms, but also contains oily particles, such as oil fume, oil mist, asphalt fume, coke oven smoke, diesel engine exhaust, etc. With regard to oily particles, gases and other chemical gases, medical protective masks can not be thoroughly filtered.

It is suggested that medical protective masks are generally used in medical and health institutions and are not suitable for ordinary people. For example, N95 mask is generally used for occupational respiratory protection to isolate some microbial particles, but it is not comfortable to wear because of its thick texture.
How to wear mask correctly
Generally, the disposable masks we buy in the drugstore are all medical ones. They usually have positive and negative sides. The darker side is blue facing outward, and the lighter side is facing inward, next to our face. Not only that, the mask is also divided into upper and lower layers. There are metal strips inside. The hard side is the upper end, which matches the bridge of nose.
1、 Cleaning: first of all, clean hands to avoid dirty hands polluting the inner appearance of the mask;
2、 Hanging: the mask is horizontally attached to the face, mouth and nose, and the rope at both ends is hung on the ears with both hands;
3、 Stretch: pull the folds of the mask up and down with both hands, so that the mask can completely cover the mouth and chin;

4、 Press: finally, press the metal pieces on both sides of the bridge of the nose with the index fingers of both hands to make the upper end of the mask close to the bridge of the nose.

In addition, we need to be reminded that: after wearing the mask, we should avoid frequent contact with the mask to avoid reducing the protective effect; After taking off the mask, wrap it with tape or paper bag, then put it into the dustbin with cover, and clean hands in time; Do not reuse disposable masks.
