respiratory infectious diseases and can reduce the risk of new coronavirus infections.

but also blocks the virus-containing droplet core and prevents the wearer from inhaling.
However, with the continuous development of the new coronavirus epidemic and the arrival of the peak return period,
the supply and demand of masks in many places are tense, and even a mask is difficult to find.
