Description

An ARM-based high-performance anti-detection haze mask with integrated ear and mouth

technical field

The utility model belongs to the technical field of sanitary protection articles, in particular to an ARM-based ear-mouth integrated high-performance anti-detection haze mask.

Background technique

PM2.5 is considered to be the culprit in the generation of haze. It can be suspended in the air for a long time, because the smaller the diameter, the deeper the part that enters the respiratory tract. After the fine particles enter the human body and enter the alveoli, it directly affects the ventilation function of the lungs. It makes the body easy to be in a state of hypoxia, which is very harmful to human health. Although most of the masks sold on the market now claim to have the function of preventing haze, they actually do not have the function of filtering PM2.5, and a few have the function of filtering PM2. The 5-function mask has a large number of filter layers to achieve the filtering effect, which affects the wearing comfort and breathability in non-haze weather.
