COVAFLU™ Disposable High Filter Face Masks help protect against influenza and other diseases by helping to prevent the virus from getting into the body through the mucus membranes of the mouth and nostrils.
COVAFLU™ complies with the World Health Organisation (WHO) guidelines for the minimisation of risk during pandemic flu. It has been designed to help protect healthy members of the general public and healthcare workers during a pandemic flu outbreak.
How are particles filtered?
Particle filtering face masks provide protection against particles, but not gases or vapours. In general, the masks are entirely made up of multiple filter material layers and can optionally include an exhalation valve. The different layers can be clearly seen in the image below. They fulfil a variety of functions, which include a good look and feel, stability, tear resistance and, of course, filtering.
