Powered Air Purifying Respirator (PAPR)
A PAPR (or tight-fitting goggles and an N-95 respirator) should be worn for high-risk aerosol-generating procedures. These respirators also meet CDC guidelines for protection against TB exposure.

Choosing a PAPR
- A PAPR may be selected for use if:
- The N95 respirator choice(s) does not fit.
- Employee has facial hair or facial deformity that would interfere with mask-to-face seal.
- The N95 respirator choice(s) are unavailable.
- Desired for high-risk aerosol-generating procedures.
- PAPRs can be used by persons who are medically certified, but who cannot wear
N95 -disposable respirators (e.g. persons with facial hair).
What is a PAPR?
- The equipment is battery operated, consists of a half or full facepiece, breathing tube, battery-operated blower, and particulate filters (HEPA only).
- A PAPR uses a blower to pass contaminated air through a HEPA filter, which removes the contaminant and supplies purified air to a facepiece.
- A PAPR is not a true positive-pressure device because it can be over-breathed when inhaling.
- A face shield may also be used in conjunction with a half-mask PAPR respirator for protection against body fluids.
Use of PAPRs
- Employees must be instructed how to put on, position, adjust, and remove respirators.
- Before PAPR use, a medical evaluation is required.
- Use of PAPRs does not require fit testing.
- Use of PAPRs does not require fit testing.
