Masks (COVID-19)

What does a mask do?

Wearing a mask is one way to protect yourself and others.

A mask acts as a barrier. Masks are one of the most effective individual public health measures that we can use to protect ourselves and others from COVID-19. When layered with other preventative measures—such as vaccination, hand washing, physical distancing, and staying home when ill—a well-constructed, well-fitting, and properly worn mask can help prevent you from getting COVID-19 and spreading COVID-19 to others.

A mask can protect others from potential COVID-19 droplets you may spread and prevents you from breathing in infectious respiratory droplets from others.

We should all do our part to reduce transmission of COVID-19 within our communities and protect the most vulnerable and our health care system.

Choosing a mask

Wear a high-quality, well-fitted, comfortable mask.

High-quality: A medical mask or respirator can provide better protection.

Well-fitted: Your mask should fit your face, covering your nose, mouth, and chin without gaping. Ties or ear loops should fit securely to avoid adjusting during use.

Comfortable: Your mask should be comfortable, easy to breathe through, and not limit your vision.

Choose the best quality and best fitting mask or respirator that’s available to you. No matter which type of mask you choose, proper fit is a key factor in its effectiveness.

Face coverings such as neck gaiters, scarves, bandanas, and face shields alone are not recommended. They are not effective filters and they do not provide a tight fit around your nose and mouth to prevent the spread of COVID-19.

Don’t use masks or respirators with exhalation valves. They allow infectious respiratory particles to escape. They do not help prevent the spread of COVID-19.
