An anti-allergic filter mask

technical field

The utility model relates to the technical field of filter masks, in particular to an anti-allergic filter mask.

Background technique

A mask is a sanitary and anti-epidemic product. It is generally worn on the nose and mouth to filter the air entering the nose and mouth, so as to block harmful gases, odors, droplets, viruses and other substances. It is made of gauze or paper and other materials. , the mask has a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, wearing a mask has a very good effect when working in a polluted environment such as dust. In order to reduce dust particles, toxic and harmful gases and infectious diseases Due to the physical harm caused by viruses to the human body, filter masks have become a must-have in daily life; To prevent floating dust below 5 μm and various germs transmitted by the respiratory tract, the protective effect of this mask depends on the filter element. The professional or quasi-professional filter element has good protection effect and high protection efficiency, but this type of professional or Quasi-professional filter elements also have the defects of high breathing resistance and poor air permeability, which leads to the inability to discharge the moisture generated during breathing. The inner layer of the mask becomes wet after absorbing water and sticks to the skin, causing discomfort, and long-term contact with the skin may cause allergies In addition, there may be a small number of unfiltered viruses and harmful gases that cause allergies. In view of this, we propose a kind of antiallergic formula filter respirator.
