Unlike disposable N95 masks, PAPR systems have loose-fitting headgear and can be worn with hair (as long as it is neatly trimmed so that it does not compromise the facepiece seal). The hoods on some PAPRs provide splash protection and reduce heat buildup. Some health care workers find PAPRs easier to use than N95s. Because they are not prone to fogging, they may be used longer during procedures. Several studies have found that incorporating PAPRs into a respirator protection program significantly reduced the number of airborne infections in hospital health care settings during both tuberculosis and severe acute respiratory syndrome (SARS) outbreaks, as well as during the Ebola epidemic.

However, there are challenges with PAPR use in head protection settings, such as the need to transport PAPRs to remote patient locations and the doffing issues presented by working in unfamiliar or confined spaces. Detailed consideration is needed to ensure that all components of PAPRs, such as the waist unit, battery, filter, and breathing tube, remain securely attached and fit comfortably, especially during transport and when doffing.

The Importance of Head Protection: Safety First in Every Environment

Other PAPR-related considerations include the need to properly maintain and disinfect PAPR filters. Health care workers should follow the instructions in the user’s manual to ensure that the correct filter is installed, and to change filters as recommended by manufacturers. Storage conditions for PAPRs and their accessories also must be considered. In general, they should be kept in a temperature-controlled environment to maximize lifespan and usability.
