![]() ![]() They provide a certain level of protection against viruses for the wearer, but should not be used when in contact with highly infectious patients. Germany required them during the 2021 third wave in busses, trains and supermarkets. FFP2/N95/KN95įFP2 masks (equivalent to other international standards known as N95, KN95 and P2 masks) are becoming more and more prevalent for elder-care and nursing homes. Bricklayers can put them on before mixing cement with trowels, kicking up some dust. Builders may wear them to catch the coarser dust that vacuum cleaners are unable to. They are intended for carpenters, for example, who work at band saws with vacuum-extraction systems. FFP1Īlthough masks of protection level FFP1 are still better than surgical masks, they do not offer the desired protection against viruses. In the European Union, these types of masks are divided into three FFP protection classes (filtering face piece). But this mask has a valve - it will not protect others. Only a FFP 3-grade mask will filter out enzymes and viruses. They are available either as disposable masks, usually made of strong pressed cellulose with a filter element and an exhalation valve, or as plastic masks in which a suitable filter is then inserted. ![]() These are more familiar to those who work in dusty environments or with aerosols. In addition to surgical masks, which look more like multilayer disposable kitchen towels, there are also half-masks with a real filter effect. The surgical masks, albeit less effective in keeping the viruses out, merely function as a constant reminder not to touch your nose with your hands when it itches. If you decide to wear a mask, you should probably also opt for protective goggles. How much protection does the mask provide?Īlthough the virus usually enters the body through the mouth or eyes, the hands play an important role in infections. If a mask of this type is worn repeatedly, it quickly loses its effectiveness.ĭuring the pandemic, higher-quality masks with better filtration have become the standard practically everywhere in the medical profession. In surgery, doctors must change their mask at least every two hours. This only works if the mask is changed regularly and disposed of hygienically and safely. If the wearer of the mask coughs or sneezes, for example, most of the droplets from the mouth and throat get caught in the mask. They consist of thin disposable tissue and fleece and are used by doctors and assistants to primarily to prevent their patients on operating tables from being infected with germs and pathogens. Such medical face masks are the professional equivalent of the cloth mask. The logic behind the mask requirement is therefore: if everyone complies, the overall risk of infection in society will fall.Ĭloth masks should be changed frequently and washed in hot water to prevent viruses from surviving. Because transmission is frequently caused by asymptomatic people, everyone is a potential virus carrier. The purpose of such masks is not to protect the people wearing them from infection: They protect the people everyone else from the wearers' germs. And this already significantly reduces the risk of infection for other people. When you exhale, it inhibits the flow of air and therefore the distance that germs can travel. ![]() This is a piece of cloth that completely covers the mouth and nose. Simple face maskĭuring most of last year, the regulation in Germany requires a simple face mask to be worn as a minimum requirement in most public areas. ![]() We explain what the different standards mean. At first, a self-made textile mask was sufficient, but later an FFP2 mask - known as KN95, N95 or P2 in other parts of the world was required. In Germany, too, masks were compulsory in public buildings and offices, on trains and buses, and in cabs during the last Corona wave. Since the onset of the Corona pandemic, most countries around the world have made masks mandatory for public spaces, mass transit and stores. A new British study shows: Hospitals in which doctors and nurses observe strict hygiene and wear FFP3 masks were able to eliminate COVID-19 transmissions by almost 100 percent. That proves: Masks do work ― some more, some less. ![]()
