But there are still various subspecies. Essentially, the masks are designed to prevent the wearer from infecting people in their vicinity with viruses or other pathogens through exhaled droplets (aerosols). According to experts, the mask wearer himself is only protected to a limited extent because many masks are permeable to aerosols. Masks do not promise 100% protection, although some are more effective than others – models with FFP2 or FFP3 filters, for example. “Each of these masks serves a different purpose. It is important that we understand the differences and know what protection each mask offers and how to handle it correctly,” these are loosely fitting masks made of fabric that are either sewn yourself or industrially manufactured. They get wet quickly and should then be changed. “Wearers of the mouth and nose covers described cannot rely on them to protect themselves or others from the transmission of SARS-CoV-2, as no corresponding protective effect has been proven for these masks,” says the BfArM. What can the mask type do? It intercepts droplets that the wearer gives off when they talk, cough or sneeze. Those who wear a cloth mask may touch their mouth or nose less often, which could reduce the risk of infection.

Where should the mask be worn? TÜV Süd recommends wearing fabric masks only in well-ventilated areas without large crowds – i.e. (as is sometimes required) in public spaces. A disposable product that is disposed of immediately after each use in the medical field. This particularly light type of mask sits loosely and therefore does not hold tight. According to the BfArM, surgical masks are tested and CE certified. Medical face mask 50 pieces, medical mouth and nose protection mask, disposable mask 3-ply, elastic ear loops and nose strips, blue. What can the mask type do? Is intended to prevent droplets of saliva from being passed on to other people. Covers the mouth and nose so that the mucous membranes there are less likely to come into contact with the hands.

Where should the mask be worn? Surgical masks have been developed for use in medical examinations or interventions, but they can also be used in ventilated public spaces if the minimum distance of 1.5 meters is observed. Safety tip: Use medical face masks no more than once and then throw them away. Then wash your hands with soap for 30 seconds. These protective masks are available in different strengths (FFP1, FFP2 and FFP3), there are also some with and without an exhalation valve. The Robert Koch Institute recommends FFP2 and FFP3 masks to protect against pathogens. According to the BfArM, they must meet the requirements of the DIN-EN-149: 2009-08 standard, bear a CE mark and should only be worn once. What can the mask type do? An FFP mask should protect both the wearer and people around him. However, the mask must not have an exhalation valve, otherwise breathing air will escape.

Where should the mask be worn? According to TÜV Süd, FFP masks are useful in full public transport, at larger gatherings or when coming into contact with infected people. Safety tip: “A beard can impair or cancel the protective effect,” warns the Institute for Occupational Safety and Health of the German Social Accident Insurance. “The best protection against potential virus transmission still offers consistent distancing from other, potentially virus-carrying people,” writes the BfArM. So it is best to always keep a distance of 1.5 meters from other people. A properly worn mouth and nose covering can nevertheless “offer a certain protective function against larger droplets and mouth / nose mucous membrane contact with contaminated hands”, according to the experts at the Federal Institute.
