From the CDC

 According to the CDC, a cloth face covering should be worn whenever people are in a community setting, especially in situations where you may be near people. These settings include grocery stores and pharmacies. These face coverings are not a substitute for social distancing. Cloth face coverings are especially important to wear in public in areas of widespread COVID-19 illness.

Best Practices:

Handle your All American Face Mask with clean hands and touch infrequently. Try not to touch or adjust Face Mask while wearing. Wash hands after removing your Face Mask. 

Wear consistently in public. Maintain social distancing (6-foot distance from others).

Cloth face coverings should not be placed on young children younger than two years of age, anyone who has trouble breathing, or is unconscious, incapacitated, or otherwise unable to remove the cover without assistance.
