Application

The role of mask breathing valve:

In a humid
or poorly ventilated or labor-intensive work environment,
using a mask with a breathing valve can help you feel
more comfortable when exhaling. The working principle of
the breathing valve is that the positive pressure of the
exhaust gas during the exhalation blows off the valve
sheet to quickly remove the exhaust gas from the body,
reducing the stuffy feeling when using a mask, and the
negative pressure when inhaling will automatically close
the valve to avoid suction Pollutants entering the
external environment.
