In the course of the CoVid-19 pandemic 2020, IRED decided to develop its own solution in the field of personal protective equipment in early 2020. The previous products, which were offered for this purpose as face protection against corona viruses, were based on bent flat films. The IRED design team, on the other hand, decided on a three-dimensional mask as a concept. This resulted in a largely closed form that is comfortable to wear, mechanically stable and aesthetically pleasing. With CLEARTECT, IRED developed an effective protection against droplets contaminated with viruses and bacteria such as those emitted by people who cough.
