Auburn University Risk Management and Safety has developed a resource page for faculty, staff and students that may be using N95 respirator face masks. This resource page can be found at and contains helpful links as well as a guidance flyer.

One of the biggest questions regarding N95 masks concerns their re-use. Currently, there is no way to determine the maximum possible number of safe reuses of an N95 respirator as a generic number to be applied in all cases. However, here are some recommendations designed to provide practical advice so that N95 respirators are discarded before they become a significant risk for contact transmission or their functionality is reduced.

• Discard N95 respirators following use during aerosol generating operations.

• Discard N95 respirators contaminated with blood, respiratory or nasal secretions or other bodily fluids.

• Discard N95 respirators following close contact with anyone co-infected with an infectious disease requiring contact precautions.

• Consider use of a cleanable face shield over an N95 respirator when feasible to reduce surface contamination of the respirator.

• Hang used respirators in a designated storage area or keep them in a clean, breathable container such as a paper bag between uses. To minimize potential cross-contamination, store respirators so that they do not touch each other and the person using the respirator is clearly identified. Storage containers should be disposed of or cleaned regularly.

• Clean hands with soap and water or an alcohol-based hand sanitizer before and after touching or adjusting the respirator (if necessary, for comfort or to maintain fit).

• Avoid touching the inside of the respirator. If inadvertent contact is made with the inside of the respirator, discard the respirator and perform hand hygiene as described above.
