Statement of the German Society for Pulmonology and Respiratory Medicine Regarding the Regulation to Use FFP and Surgical Masks in the General Population
On January 19, 2021, a new regulation on the mask requirement was issued in an initiative by the federal and state governments. This regulation obliges citizens to wear medical masks on public transport and in shops. In its statement, the German Society for Pneumology and Respiratory Medicine (DGP) describes the technical background of the various medical masks and explains their functionality using the associated standards. The DGP comes to the conclusion that FFP masks of the EN 149 standard were designed for the self-protection of the wearer and ensure this if the mask is worn properly and closes tightly to the face. Incorrect use must be avoided at all costs. Surgical masks in accordance with the EN 14683 standard were designed to protect against bacteria-carrying aerosols and, due to their design, have a rather low self-protection component. Community masks are not yet subject to any official standard. Community masks with electrostatic properties and high filtration performance could represent a reusable alternative in the future. Depending on the severity of their illness, patients with heart and/or lung diseases require a stress test with a mask to minimize medical risks.
