How do you wear blue or white masks?

- Apr 29, 2020-

Place the colored side (blue or green) of the mask in front, away from your face, place the white part inside, and touch your face. The blue side is waterproof, preventing bacterial droplets from sticking to it. On the other hand, the white part is an absorbent material that can absorb water droplets from coughing or sneezing.
