Gauze mask is a kind of protective equipment often used in medical treatment. Gauze mask also plays a role in other industries, such as working in the environment of some harmful gases or steam, which also requires the use of gauze mask

Gauze mask has the function of dustproof and virus-proof, can filter the toxic substances to the human body, which is very important for health.Woven dust respirators are respirators that only protect the respiratory organs from harmful substances.Generally, it is composed of a mask and a poison filter box, which is equipped with adsorbent or sorbent and has a very good adsorption effect.Some boxes also have a filter layer that protects against aerosols.And the military use of anti-toxic masks are mainly made of activated carbon cloth, or with anti-water and anti-oil fabric as the outer layer, glass fiber filtration material as the inner layer, immersed in activated carbon polyurethane foam plastic as the bottom layer, can provide temporary protection when suddenly attacked by poison gas.There are many kinds of respirators, but in terms of structure and working principle, they are mainly divided into two categories: air filter masks and air supply masks.
