What does the valve do?

The valves perform a key role in safety, by reducing CO2 build-up and reducing humidity, which can encourage viral and bacterial growth. The valve is designed in a way that reduces potential droplet spread as much as possible without compromising the overall effectiveness of the mask as a valuable piece of PPE. Cambridge Mask Co valves are designed with a silicone gasket inside a casing. The cap of the valve opens downwards, pushing exhaled breath downwards and not outwards towards people who may be around you. The casing on our valve is designed to create a directional flow which helps to reduce droplet spread.
