Key Information to note:
We want to stress that wearing ANY mask does not guarantee you won't contract or transmit the virus to other. By creating a barrier that reduces particle spread it does however mitigate the risk you face (and potentially pose to others) in public spaces. It is most important to continue following all government guidelines including:
Continue to follow social distancing 2-meter rule
Wash your hands frequently for at least 20 seconds
Do not touch your eyes, nose, and mouth
Isolate yourself if showing any signs of illness
Please familiarise yourself with our user guide (hard copy sent with purchase)
