Face masks help prevent the spread of COVID-19 when worn consistently and correctly. Here are considerations to help you choose a mask and ensure you get the best protection from it:

  • Filtration. While all masks provide some level of protection, properly fitted high filtration masks such as N95s, KN95s, and KF94s offer the best protection. In the absence of a high filtration mask, you can improve the protection of your mask by wearing two masks. An example of this could be that you wear a cloth mask over a disposable mask.

  • Fit. A mask may be less effective if it is not the right size for you, worn improperly, or taken off frequently. Ensure that your mask is the right size to provide a tight seal on your face. If you have facial hair, you may need a larger mask to ensure that you have a secure fit. Masks should fit snugly over your nose and mouth with no gaps. Fit can be improved by combining a cloth mask or disposable mask with a fitter or brace at the nose, knotting and tucking ear loops of your mask, or wearing a mask that is secured behind the head instead of secured with ear loops.

  • Comfort. Some masks are more protective than others, and some are more comfortable than others. High filtration masks, such as N95s, KN95s, and KF94s are recommended. You can get the best protection against COVID-19 by consistently wearing the most protective mask that fits you well.
