Masking
Policy
Masks are optional indoors in most spaces on Emory’s campuses.
Exceptions include the following:
- Mask requirements vary for clinical, patient care, and select research facilities on campus, including but not limited to Student Health Services. Please refer to the mask policies defined by your unit.
Should health indicators change or heightened risks emerge, indoor mask requirements may be reinstated.
As we adjust to living with COVID-19 in a highly vaccinated community, many will welcome this new change while some may have concerns. “Mask optional” means it is each individual’s personal choice to wear a mask or not, and our collective community response must be one that honors and respects these choices. Anyone who needs to or prefers to wear a mask is encouraged and welcome to do so.
For those who are in high-risk categories or require additional support, please visit the Resources page.
Types of Masks
| Mask Type | Pros | Cons |

| Filters approximately 95% of COVID-19 particles | Not as effective if worn improperly | |
| Standard for health care professionals | Can be uncomfortable to wear for longer periods of time | |
| K95 | Filters approximately 95% of COVID-19 particles | Not approved by NIOSH |
| Can be molded to wearer's face | Masks are manufactured in China and can be difficult to obtain | |

Mask Guidance
The most important factors to consider when choosing a mask are fit, quality, and consistency.
Fit: A properly fitting mask should cover both the nose and mouth. Air should not escape from a mask when a person exhales. If exhaling causes an individual’s glasses to fog, the nose bridge on the mask needs to be pinched tighter to the face.
The CDC has shared recommendations for improving the fit of different kinds of masks on its website. For example, the fit of three-ply masks can be improved by knotting the ear loops and folding excess material under the edges of the mask.
Quality: A quality mask has multiple layers to filter out particles. Cloth masks vary in quality, so it is difficult to determine how effective they are at filtering COVID-19 particles. Cloth masks can be protective if they are well-fitted and have multiple layers. Look for cloth masks with adjustable ear loops, nose bridges, and a filter pocket.
Consistency: Masks that act as respirators (like N95 masks), while high quality, require special fitting, and can be uncomfortable to wear for longer periods of time for those in non-health care settings. It is important to wear quality masks that fit well and can be worn comfortably for a long period of time.
