Can medical masks prevent haze?

- Nov 02, 2018 -


First of all, we must recognize the concept of "haze". Haze is a combination of fog and haze, and its damage is far greater than that caused by fog and haze. The main "members" of haze are sulfur dioxide, nitrogen oxides and dust particles, the first two are gaseous, the latter are small solid particles. Usually, the outdoor concentration of haze is relatively high. It mainly includes non oily granular matter and oily granular matter. Non-oily particulate matter mainly refers to dust, coal dust, limestone; and oily particulate matter refers to automobile exhaust fume, oil mist, diesel engine exhaust, etc. What is an anti fog mask? Fogging masks must also contain oil and non oil particles.


The dust mask is different from the ordinary dust mask. There are two common types of dust respirators: Civil dust respirators and industrial dust respirators. The protective properties of these two kinds of dust respirators are unilateral anti fogging. Mask protection requirements are higher.


In addition, the concept of medical masks is that medical masks are mainly used in the medical industry, generally used in medical rooms, hospital wards and operating rooms. Medical masks can only effectively prevent non-oily particles in the environment from being inhaled by the human body. It is impossible to separate oily particles such as lampblack, and can not effectively protect gaseous compound particles. In addition, the domestic GB19083-2010 technical requirements for medical protective masks mentioned that medical masks need to meet the filter efficiency of non-oil particles should not be less than 95%, and the filter efficiency of oil particles is not defined.
