Breathing valve masks are designed for the health of the human body, and are used to prevent the visible or invisible substances in the air that are harmful to the human body from filtering, so as not to bring bad effects to the human body.

In working environments that are hot or humid, poorly ventilated, or labor-intensive, using masks with breathing valves can help people feel more comfortable when they exhale. The working principle of the breathing valve is that the positive pressure of the exhaust gas blows open the valve plate during exhalation to quickly remove exhaust gas from the body and reduce the stuffiness when using the mask. The negative pressure during inhalation will automatically close the valve to avoid breathing. Pollutants entering the external environment.

When respiratory infectious diseases are prevalent, and when working in dust and other polluted environments, wearing masks has a very good effect.
