Our masks are considered personal protective equipment (PPE) meaning that they protect the wearer during usage.
While we have not run specific tests regarding COVID19, prior to the pandemic our PRO mask had been tested to filter more than 99% of viruses and bacteria. You can find the results of these tests here.
The valve on our masks plays a vital role in helping to reduce moisture preventing the buildup and growth of viruses and bacteria, as well as limiting the excess build-up of carbon dioxide. This is why the valve opens when you exhale.
These elements are a key part of the EN149 certification that our masks are required to adhere to under European Union testing and regulation.
