    Correct and consistent mask use is a critical step everyone can take to reduce their risk of getting and spreading COVID-19. Masks work best when everyone wears them, but not all masks provide the same protection. How well a mask fits, how well it filters the air, and how many layers it has are all important to consider when choosing which mask to wear. Wearing a mask around people who do not live with you or when someone in your house is sick is now even more critical with the increased spread of new COVID-19 variants, some of which appear to spread more easily and quickly than the original virus that causes COVID-19.
