Our exhalation valves are perfect for individuals and businesses looking to produce face masks for use in the workplace or in general public.
The role of mask exhalation valves
In a humid or poorly ventilated or labour-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 from the external environment.
Exhalation valves are available in black and white options, are sold in packs of 20 and are available on next day delivery.
