Our FFP2 disposable masks comply with the European standard EN 149 and are approved by a CE-certified body. Our surgical masks comply with the EN14683 IIR standard. In contrast to professional masks such as FFP2 or Type IIR, the washable masks are so-called "community masks" which, from a technical point of view, do not have to meet a standard, but we ensure that they comply with the national recommendations of Switzerland.
