Masking Information from the Texas Department of State Health Services

The Texas Department of State Health Services states "vaccinated or not, wearing a mask in indoor public spaces, can help protect you and everyone close to you." You can read more health recommendations from the Texas Department of State Health Services to help protect you and those around you by visiting their website.

Your Guide to Masks

The Centers for Disease Control and Prevention has provided a guide to wearing a mask. You can visit the CDC website for more information or read the details below. 

Wearing a mask over your nose and mouth is required on planes, buses, trains, and other forms of public transportation traveling into, within, or out of the United States and while indoors at U.S. transportation hubs such as airports and stations. Travelers are not required to wear a mask in outdoor areas of a conveyance (like on open deck areas of a ferry or the uncovered top deck of a bus).

How to Select

When selecting a mask, there are many choices. Here are some do’s and don’ts.

Special Considerations

People with beards

Certain types of facial hair, like beards, can make mask fitting difficult. Masks that fit well protect you better. To have a better fit, people with beards can shave their beards or trim their beards close to the face.

Other ways to improve fit

For people with beards that are not trimmed close to the face, masks may fit loosely around the beard. However, people with beards should still wear a mask. Masks designed for people with beards are being evaluated, and information will be provided when it becomes available.

Wearing a mask does not raise the carbon dioxide (CO2) level in the air you breathe

Cloth masks and surgical masks do not provide an airtight fit across the face. The CO2 escapes into the air through the mask when you breathe out or talk. CO2 molecules are small enough to easily pass through mask material. In contrast, the respiratory droplets that carry the virus that causes COVID-19 are much larger than CO2, so they cannot pass as easily through a properly designed and properly worn mask.

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.
