Manufacturers wholesale air filter breathing valve accessories three piece one way exhaust breathing valvee

Respiratory valve function: used to prevent the filtering of visible or invisible substances harmful to human body in the air,

In a working environment with atmospheric pollution, high temperature and humidity, poor ventilation, or heavy labor, using a mask with a breathing valve can help you feel more comfortable when exhaling.

The function principle of the breathing valve is that the positive pressure of the exhaust gas during exhalation blows off the valve sheet to quickly remove the exhaust gas in the body, avoiding the leakage of the wet mask through the mask filter cloth, and keeping the mask dry and breathable for a long time, reducing the sultry feeling when using the mask And the negative pressure during inhalation will automatically close the valve to avoid inhaling the pollutants in the ambient air.
