Whats the question? i cant help you if you dont tell me the questions.
Masks are a key measure to suppress transmission and save lives. These masks are intended for industrial workers to prevent dust and particles from being breathed in as the valve closes on inhale. However, the valve opens on exhale, making it easier to breathe but also allowing any virus to pass through the valve opening. This makes the mask ineffective at preventing the spread of the virus or any other respiratory virus.
hope it helps :)
