It relates to a clean air blower type mask that can be.

In recent years, air pollution including fine dust due to natural yellow sand and industrialization is becoming more serious, and harmful substances that pollute the environment such as carbon monoxide and viruses as well as fine dust are gradually increasing with industrialization. Hazardous substances are being refined into nanoscale.

Accordingly, when harmful substances such as fine dust having a particle size of 1 to 10 μm are introduced into the human body through the respiratory tract, it may be deposited in the bronchi, including the lungs, and serious diseases may be caused. Therefore, going out without wearing a mask when going out May be fatal to the respiratory system.

However, it is difficult to completely block fine dust due to the wide pores of a general mask formed of a fibrous tissue, and to compensate for this, a multi-ply mask formed of a multi-ply non-woven material has been disclosed. It does not block dust.

In addition, the better the sealing effect, the more carbon dioxide is not discharged to the outside, blocking breathing, so there is a high possibility of adversely affecting the health of respiratory patients, heart disease patients, and pregnant women.
