Company history

Our company history

We have 35 years of experience in the field of environment and filter technology. We have also been working in the area of ​​thin film technologies and the development of filter media for 23 years. After several positions, we founded our first environmental and filter technology company in 1988. In this company we managed to develop a mercury protective mask in 1997 in collaboration with Dr.med. Dipl. chem. Lichtnecker and the Institute for Environmental Technology and Analytics e. V. (IUTA) in Duisburg. Since 2004, we have been selling and manufacturing this mercury protective mask with the company Prophy-Dent, which we founded.
