KN95 face masks offer better filtration than cloth or surgical masks. But which protect you from COVID and new variants? These 14 options are CDC approved.
A team from the Commonwealth Scientific and Industrial Research Organization (CSIRO) revealed that exposing N95 and P2 face masks to alcohol-based sanitisers risks "serious degradation" of their ability to protect from airborne hazards.
The US Centers for Disease Control and Prevention on Friday revised its guidance for Americans on wearing masks to protect against COVID-19, recommending donning "the most protective mask you can" while stopping short of advocating nationwide usage of N95 respirators.
As per the latest study published in the Journal of Infectious Diseases, the face masks help in reducing the distance airborne pathogens could travel when speaking or coughing by more than half compared to not wearing a mask.
Ever since the coronavirus (COVID-19) pandemic wreaked havoc across the world, scientists and health experts have been advocating the usage of face masks to curb the spread of the virus.
