The purpose of masks is to keep respiratory droplets from reaching others to aid with source control. Masks with one-way valves or vents allow exhaled air to be expelled out through holes in the material. This can allow exhaled respiratory droplets to reach others and potentially spread the COVID-19 virus. The CDC does not recommend using masks if they have an exhalation valve or vent.
Additional research is still being conducted on the effectiveness of various forms of cloth face coverings. A recent “proof-of-concept” study by researchers at Duke University found that porous neck gaiters and bandanas were not as effective as three-layered cloth face covering. For these reasons, CFL requires that students and employees not wear masks with valves, neck gaiters, or bandanas.
Cloth face coverings are not surgical masks, respirators, or other medical personal protective equipment. Face coverings should be worn by staff and students, and are most essential in times when physical distancing is difficult. We will remind each other frequently not to touch the face covering and to wash our hands. Students are required to purchase their own cloth masks for classes.
Cloth face coverings will NOT be placed on:
Students can find more information on the proper use, wearing, removal, and cleaning of cloth face coverings, such as CDC’s Guidance on wearing and removing cloth face masks and CDC’s use of cloth face coverings.
