It relates to a portable air sterilizing mask that can prevent the spread of droplets, germs, and germs, and can be easily carried by modularizing an air sterilizing configuration.

Today, due to global warming and environmental pollution, the occurrence of yellow dust and fine dust is frequent, and especially due to the pandemic of infectious diseases such as coronavirus infection (COVID-19), health masks have become essential items in real life.

Among these health masks, the filtering face mask is mainly composed of MB (Melt Blown) between non-woven SB (spunbond) outer fabrics to block the penetration of viruses, including yellow dust and fine dust, into the respiratory tract and prevent infection through droplets (saliva droplets). ) It is made of a structure in which a filter is inserted, and it is formed to be worn by hanging the straps on both sides of the ear to cover the wearer's mouth and nose.

When worn for a long time, it interferes with normal breathing due to inhalation resistance, which is quite stuffy and uncomfortable, as well as causing contact dermatitis such as skin trouble by stimulating areas in direct contact, such as around the mouth and chin, as well as causing problems such as 10 hours If it is used more than that, there is a limit in that the blocking effect is significantly reduced.

In addition, the virus blocked by the MB filter exists around the wearer's respiratory tract, and there is a risk of inflow into the body through the respiratory tract or causing infection.

In particular, since virus particles have a size of 0.02-0.3㎛, which is about 1/100 smaller than normal bacteria, there is a limit that it is difficult to block them even if a high-performance filter such as a HEPA filter is built into the mask.
