Can disposable medical face masks filter haze?

Restriction of air pollution is particularly serious. Now it is cold winter. Haze weather often occurs in many places. Haze threatens people's health. Therefore, many users wear masks to cover when traveling. However, many users will ask whether medical masks can filter haze in the end. The editors of medical mask manufacturers will give a brief introduction to the users, hoping to help everyone.

Disposable medical face masks include ordinary medical masks, medical surgical masks and medical protective masks, among which the medical protective masks have a high protection level. It is made of 3 layers of materials. The inner layer is mostly non-woven fabric. The middle layer is ultra-fine polypropylene fiber meltblown material layer. The outer layer is non-woven fabric or ultra-thin polypropylene meltblown material. The filtering effect of virus aerosol or harmful dust is remarkable, and the blocking and filtering efficiency of non-oily particles in the air is ≧ 95%.

Although this mask has good filterability, it cannot completely filter. Because the smog not only contains non-oily particulate matter, such as dust, acid mist, coal dust, cement dust, microorganisms; it also contains oily particulate matter, such as soot, oil mist, asphalt smoke, coke oven smoke, diesel exhaust and so on. For oily particles and gaseous chemicals, medical protective masks cannot be completely removed.

It should be reminded that medical protective masks are usually used in a medical environment and are not very suitable for ordinary people to wear in daily life. For example, N95 masks are usually used for occupational respiratory protection, blocking certain microbial particles, but because of their thick texture, they are usually uncomfortable to wear.
