Many indoor spaces are contaminated with pollutants that we cannot see with the bare eye. Especially in crowded areas and production facilities. Appropriate ventilation systems must be installed to achieve the mandatory Occupational Exposure Limits (OELs). Conventional ventilation systems that use filters to bind the pollutants require a high amount of energy to maintain the temperature and process the incoming fresh air. With such systems, the ventilation process is very time-consuming and complicated in order to ensure proper ventilation.

The combination between UV radiation and photocatalytically active façade paints and plasters with TiO2 particles purifies the air and eliminates dangerous viruses, bacteria, fungi, and many other harmful organic compounds in the air.
