Description

Anti haze deodorant mask

technical field

The utility model belongs to the technical field of breathing masks, in particular to an anti-haze and deodorizing mask.

Background technique

PM2.5 is the main component of smog, which not only affects the health of the respiratory tract and lungs, but also contains heavy metals that are fatal. In order to avoid smog pollution, masks have become the first choice of ordinary citizens. However, most of the mask products currently on the market cannot filter PM2.5. The test results of the China Consumers Association in 2014 showed that only a very small number of foreign products met the removal efficiency requirements, and most of these products were designed for industrial production. The safety and aesthetics are difficult to meet the requirements of civilian use. When the wearer uses these masks to inhale and exhale, on the one hand, the internal and external exchange of air will be slow, causing the wearer to feel insufficient air supply. Air gas stays inside the mask for a long time, and the humidity is high, which affects the health of the facial skin.
