a person with a single-use pleated surgical mask. The mask nose bridge is pinched to fit to the person's nose and fixed to the ears with elastic ear loops. The vapor is more contained in this image, but still noticeably escapes out the top of the mask and out the sides, where the mask lacks a tight seal to the face. This demonstrates the spread of airborne particles and vapors with a surgical mask, compared to no mask / N95.
