During the ongoing COVID-19 pandemic, healthcare professionals are at the
forefront of managing the highly infectious coronavirus. As the most common route
of transmission is via aerosols and droplet inhalation, it is critical for
healthcare workers to have the correct personal protective equipment (PPE)
including gowns, masks and goggles. Surgical masks are not effective in
preventing the influenza and SARS, so they are unlikely to be able to resist
contaminated aerosols from entering the respiratory system. Therefore, it is
vital to use respirators which have been proven to offer better protection
against droplets, aerosols and fluid penetration and which form a tight seal
around the mouth and nose. Various types of respirators are used in healthcare
settings, such as half-mask filtering facepiece respirators (FFRs) and powered
air-purifying respirators (PAPRs). The most commonly used FFR is the N95
disposable respirator, which is tight fitting and has a 95% or above particle
filtering efficiency for a median particle size of 0.3 µm. This review discusses
respirators, their purpose, types, clinical efficiency and proper donning and
doffing techniques.
