Table 4 Logistical advantages and disadvantages of PAPR, adapted from Wong et al. [27]
Advantages of PAPR | Disadvantages of PAPR |
|---|---|
PAPRs use only HE filters, which have a greater filtration efficiency against the smallest pathogen particles compared to face-filtering respirators (FFRs) | Challenges in verbal communication |
PAPR systems have assigned protection factors (APF) of at least 25 | May limit the visual field |
Provides eye protection (hooded models only) | Inability to auscultate chest |
PAPRs with loose-fitting headgear can be worn with a limited amount of facial hair | Proper maintenance of PAPR requires disinfection, cleaning, safe storage, and battery maintenance |
Inability to re-use disposable filters between patients (need a large supply of filters) | |
Risk of battery failure and inadvertent exposure | |
Requires decontamination after use | |
More expensive than individual N95 respirator (although achieve more wears per piece of equipment with PAPR) | |
Requirement for the education of a significant proportion of HCW workforce |
