This is the non-moisture-permeable variant. It is intended to protect the nasal and oral mucous membranes from splashes of body fluids. RIVM recommends the use of type IIR masks for general care procedures, including patients infected with the coronavirus. In addition, it helps the user to avoid touching their own mouth or nose with their own hands. They are made with a pleated front with fabric ear loops and have an adjustable nose piece and a retention band that keeps the mask in place. They are used to cover the mouth and nose against sprays, vapors and particles.
