Sterilisation method enables reuse of face masks
Exploratory research at Maastricht University Medical Center+ has demonstrated that medical FFP2 face masks can be made completely germ-free through plasma sterilisation. This means that a mouth and nose mask can be used three times instead of being discarded after a single use. This method was validated today by the National Institute for Public Health and the Environment (RIVM).
Plasma sterilisation uses hydrogen peroxide at a lower temperature than, for example, steam sterilisation. When this process is carried out in a vacuum, a temperature of 60°C is sufficient to kill all microorganisms. Many heat-sensitive materials, such as plastics or electrical components, can therefore be sterilised using this method without melting. A single plasma steriliser can currently prepare a maximum of 2400 face masks per day for reuse.
