Respiratory protective equipment (RPE) is the umbrella term for every device that protects breathing — from disposable N95s and FFP3s to powered and supplied-air systems. This guide maps the full family tree, the adequate-and-suitable selection test, fit testing rules, and how the US, UK, EU, Canadian, and Australian rulebooks attach.

A PAPR uses a blower to push filtered air into a hood or mask, giving higher protection and far more comfort than a tight-fitting respirator, often without a fit test. This guide explains how a powered air-purifying respirator works, its assigned protection factor, how it compares to half- and full-face respirators, and who actually needs one.
