How to choose a Face Mask
If the face mask only consist of BFE, what must the percentage is? more than and equal to 95%? for protest us from COVID-19. Is that PFE is important for face mask or BFE only or both? and is the face mask name is important? such as surgical face mask/ filter face mask/ face mask…

Greetings!
I understand your dilemma to prevent possible spread of COVID-19.
As for now the World Health Organization has recommended the general population to wear surgical mask whilst healthcare workers to wear N95 facemask. To protect against the infection, it is highly recommended to those who are sick or with COVID-19 symptoms. You can wear it if you are healthy but it is not as effective as compared to those who are sick.
Thank you for your question.
