A mask is an object normally worn on the face, typically for protection, disguise, performance, or entertainment, and often employed for rituals and rites. Masks have been used since antiquity for both ceremonial and practical purposes, as well as in the performing arts and for entertainment.
Research suggests wearing a mask is a highly effective way to protect yourself and others against COVID-19, the flu and other respiratory infections.
Assuming the mask fits well and its filtration has been rigorously tested, N95 or KN95 respirators and surgical masks are some of the most protective face coverings you can buy.
Here are the basics of how to wear a mask: Clean your hands before you put your mask on, as well as before and after you take it off, and after you touch it at any time. Make sure it covers both your nose, mouth and chin.
