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

Cleaning and disinfecting

  • Recommendation on cleaning and disinfection differ among manufacturers.
    • PAPRs should be cleaned according to manufacturers recommendations.
      • NIOSH recommends to clean loose-fitting PAPRS:
        • Remove the hood or helmet from the respirator and clean with a detergent solution.
        • Clean the suspension inside the head gear in a similar fashion.
        • Clean and sanitize the protective face shield.
