Due to the deterioration of air quality, the haze weather phenomenon is increased, and the harm is increased. In many areas of China, haze and sand weather phenomena are combined into fog to be used as a disaster weather early warning forecast. Collectively referred to as "haze weather". Experts recommend that haze weather is reduced as much as possible when going out, and the qualified mask is worn when going out, so that the mask is beneficial to human health.
Microorganisms such as bacteria, viruses, mycoplasma chlamydia and the like exist in the air, and are generally attached to suspended particles in the air and spread along with the air flow. It may cause asthma, pneumonia and other infectious diseases in human body, and even death of serious people due to infection. Except for a few gauze masks, the masks sold in the market at present are made of non-woven fabrics. Most non-woven fabrics material though can play the effect that blocks particulate matter in the air, nevertheless do not have the effect of suppressing and killing to various fungus class in the air, and lack waterproof measure, when rainwater weather uses, because the infiltration of rainwater reduces the protecting effect easily, causes life to shorten, can not satisfy user's demand.
