Disposable Medical Mask Can Filter Smog

With the continuous development of society, air pollution has become more and more serious. In many places, fog and haze weather often occurs, and people will wear masks when they appear. However, many users prefer disposable medical masks, so can disposable medical masks filter haze? The following editor of disposable masks will give a brief introduction to the majority of users.

Disposable medical masks include general medical masks, medical surgical masks and medical protective masks, among which medical protective masks have the highest protection level. It is made of 3 layers of material, the inner layer is mostly non-woven fabric, the middle layer is a layer of ultra-fine polypropylene fiber melt-blown material, and the outer layer is a non-woven fabric or ultra-thin polypropylene melt-blown material; Virus aerosol or harmful fine dust has a remarkable filtering effect, and the blocking and filtering efficiency of non-oily particles in the air is ≧ 95%.

Although the filterability of this mask is good, it cannot be completely filtered. Because the smog contains not only non-oily particulate matter, such as dust, acid mist, coal dust, cement dust, and microorganisms; it also contains oily particulate matter, such as oil smoke, oil mist, asphalt smoke, coke oven smoke, diesel exhaust, etc. Medical protective masks cannot completely filter out oily particulates and gaseous chemicals.

Medical protective masks are usually used in the medical care environment, and are not very suitable for ordinary people to wear in daily life. For example, N95 masks are commonly used for occupational respiratory protection, blocking certain microbial particles, but because of their thick texture, they are not usually comfortable to wear.
