Proper Face Mask Usage: Avoid Common Mistakes That Reduce Protection #3787725 (License: Personal Use)

This illustration highlights two common face mask errors: masks worn below the nose and chin, marked with red X icons on the ears to emphasize incorrect placement. The stylized side-profile figures-a man in green and a woman in red-demonstrate how improper fit reduces filtration efficiency and increases exposure risk. Public health guidance stresses that masks must snugly cover the nose, mouth, and chin to be effective.

Used in public health campaigns, CDC/WHO educational materials, and pandemic safety guides to visually reinforce correct mask usage; targets users searching for “how to wear a face mask properly” or “common mask mistakes.”
