We provide a model with a special anti-microbial coating. We use this to cope with a few fields of application, which face very special levels of exposure to bacteria. However, in principle, we do not recommend any products with an anti-microbial surface. Firstly, the general and active effectiveness against relevant germs is too low. Secondly, evidence has suggested that this provides an illusory sense of security and leads to neglect in hygiene practices. It is our belief that anti-microbial surfaces on their own do not improve hygiene levels.
