Corona - Which masks protect best?

Aerosols are considered the transmission route for the corona pathogen. These are tiny virus-containing particles that become airborne when people talk, sneeze or cough. Masks can help reduce aerosol dispersion and thus lower the risk of infection indoors.

Aerosols are considered the transmission route for the corona pathogen. These are tiny virus-containing particles that become airborne when people talk, sneeze or cough. Masks can help reduce aerosol dispersion and thus lower the risk of an infection indoors.

The range of mouth-nose coverings is huge. Yet which mask is suitable? According to current tests and studies, there are big differences between the models. Cloth masks and simple medical face masks mainly protect the others. Some of the exhaled particles remain trapped in them and do not escape into the environment. For the wearer, however, they do not offer reliable protection. Nevertheless, they can be sufficient for short stays indoors and if the distance rules of at least 1.5 metres are observed. For longer stays indoors with other people and wherever an increased risk of infection is to be feared - for example, in a doctor's waiting room or on public transport - only FFP masks can also adequately protect the wearer.

When using a fabric mask, you should choose masks made of several layers of fabric and ensure a good fit. They are reusable and should be washed at a minimum of 60 degrees.

Medical face masks consist of three thin layers of fleece. The fine wire in the mask is easy to press onto the nose so that glasses do not fog up so easily. When buying, look for the CE mark for medical products and change these disposable masks at least once a day. Worn masks belong in the household waste.

FFP2 masks should also reliably protect the wearer and filter out at least 94 percent of the aerosols in the inhaled air. The abbreviation stands for "Filtering Face Piece". The dense material hardly lets particles such as viruses and dust through. Avoid models with valves for exhalation: air contaminated with viruses could flow out. Especially with the even denser FFP3 masks, breathing can be difficult. These are therefore only recommended for contact with covid patients. FFP masks are available in pharmacies, DIY stores and online. When buying, look for the CE mark with a four-digit test number, EU standard EN 149 and supplier address. Some of these masks can be prepared according to supplier specifications and used more often. They are then marked with an "R" for reusable.
