The Center for Disease Control and Prevention (CDC) issued an order on January 29, 2021, following an executive order that as of February 1, 2021 at 11:59 p.m., masks are required inside all U.S. airports.
Masks are defined as a covering that goes over both the nose and the mouth. Additional information from the CDC regarding masks states:
The following are attributes of masks needed to fulfill the requirements of the Order. CDC will update this guidance as needed.
- A properly worn mask completely covers the nose and mouth.
- Cloth masks should be made with two or more layers of a breathable fabric that is tightly woven (i.e., fabrics that do not let light pass through when held up to a light source).
- Mask should be secured to the head with ties, ear loops, or elastic bands that go behind the head. If gaiters are worn, they should have two layers of fabric or be folded to make two layers.
- Mask should fit snugly but comfortably against the side of the face.
- Mask should be a solid piece of material without slits, exhalation valves, or punctures.
The following attributes are additionally acceptable as long as masks meet the requirements above.
- Masks can be either manufactured or homemade.
- Masks can be reusable or disposable.
- Masks can have inner filter pockets.
- Clear masks or cloth masks with a clear plastic panel may be used to facilitate communication with people who are hearing impaired or others who need to see a speaker’s mouth to understand speech.
- Medical masks and N-95 respirators fulfill the requirements of the Order.
The following do not fulfill the requirements of the Order.
- Masks worn in a way that does not cover both the mouth and nose
- Face shields or goggles (face shields or goggles may be worn to supplement a mask that meets above required attributes)
- Scarves, ski masks, balaclavas, or bandannas
- Shirt or sweater collars (e.g., turtleneck collars) pulled up over the mouth and nose.
- Masks made from loosely woven fabric or that are knitted, i.e., fabrics that let light pass through

- Masks containing slits, exhalation valves, or punctures
- Masks that do not fit properly (large gaps, too loose or too tight)
