We here at Cambridge Mask Co. believe valves perform a key role in safety, by reducing CO2 build-up and reducing humidity, which can encourage viral and bacterial growth. Our 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.
The valve consists of 3 parts: outer disk, inner membrane, and inner disk. Cambridge Mask Co. valves are designed with a silicone gasket as the inner membrane inside a casing. The inner membrane opens when you exhale and closes when you inhale. The easiest way to see this in practice would be to look in the mirror and observe the inner membrane opening and closing as you breathe. The valve opens and closes at the exact time you are exhaling and inhaling. 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.
