08.02.2021 - Feature on FFP masks on 3sat

In the context of the 3sat contribution (link) we could show that permissible differences in the test standard EN149 can lead to different measuring results with the examination of so-called FFP masks. From the contribution it becomes clear: No mask offers 100% protection - not even an FFP2 mask. The use of higher-quality masks (i.e. OP mask, but especially FFP2 instead of "everyday mask") basically increases the effectiveness of the component in the overall concept. If "incorrectly worn" FFP2 masks "only" offer 50-60% overall separation efficiency due to "leakage ", this is always better than the separation efficiency of everyday masks (which is often less than 10%). Even if the effectiveness of the "mask" component is increased, the following still applies in addition: distance, reduce the number of people, reduce the duration of stay, ventilate & use indoor air filters if necessary.
