Your Guide to Masks
CDC recommends that people wear masks in public settings, at events and gatherings, and anywhere they will be around other people. Effective February 2, 2021, masks are required on planes, buses, trains, and other forms of public transportation traveling into, within, or out of the United States and in U.S. transportation hubs such as airports and stations.
How to Select
When selecting a mask, there are many choices. Here are some do’s and don’ts.
Have two or more layers of washable, breathable fabric
Completely cover your nose and mouth
Fit snugly against the sides of your face and don’t have gaps
Have a nose wire to prevent air from leaking out of the top of the mask
Are made of fabric that makes it hard to breathe, for example, vinyl
Have exhalation valves or vents which allow virus particles to escape
Are intended for healthcare workers, including N95 respirators
Special Considerations
Wear a gaiter with two layers, or fold it to make two layers
Not recommended: Evaluation of face shields is ongoing, but effectiveness is unknown at this time.
Find a mask that is made for children to help ensure proper fit
Check to be sure the mask fits snugly over the nose and mouth and under the chin and that there are no gaps around the sides
Do NOT put on children younger than 2 years old
Wear your scarf, ski mask or balaclava over your mask
Scarves, ski masks and balaclavas are not substitutes for masks

How to Wear
Wear a mask correctly and consistently for the best protection.
- Be sure to wash your hands or use hand sanitizer before putting on a mask.
- Do NOT touch the mask when wearing it. If you have to often touch/adjust your mask, it doesn’t fit you properly, and you may need to find a different mask or make adjustments.
