Now air pollution is serious, especially in winter, haze attacks from time to time. Once inhaled, haze will pose a threat to human health. Everyone has their own tricks, but most of them are covered with masks, but now there are a wide range of products advertised as "dust and haze proof medical masks" on various websites, sales stores and medical stores, which makes people dazzled. Then, can disposable medical masks filter haze? Next, Xiaobian will analyze it for you.


  Disposable medical masks include ordinary medical masks, medical surgical masks and medical protective masks, of which the protection grade of medical protective masks is higher. It is made of three layers of materials, the inner layer is mostly 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; It has significant filtering effect on micro virus aerosol or harmful micro dust of Liming hydraulic filter element, and the blocking and filtering efficiency of non oily particles in the air is ≥ 95%.

Although the filtering property of medical mask is very good, it can not be completely filtered. Because haze not only contains non oily particles, such as dust, acid mist, coal dust, cement dust and microorganisms; It also contains oily particles, such as oil smoke, oil mist, asphalt smoke, coke oven smoke, diesel engine exhaust, etc. Oily particles, gaseous chemicals and medical protective masks cannot be completely filtered out.

Xiaobian reminds you that disposable medical masks are usually used in medical environment and are not very suitable for ordinary people to wear in daily life. For example, N95 mask is usually used for occupational respiratory protection to block some microbial particles, but it is not comfortable to wear because of its thick texture.
