N95 or equivalent respirators are single-use personal protective equipment (PPE) designed for use by health workers that provide direct care to patients with diseases transmitted by aerosols or during aerosol generating procedures (AGP) for patients with acute respiratory disease, as is the case of COVID-19. • Given the current shortage of N95 and equivalent respirators, the World Health Organization (WHO) has suggested the possibility of their extended use by the same individual for up to 6 hours or the reprocessing of respirators when necessary.
