How does it work?
The Pureti technology creates self-cleaning surfaces that purify the air by means of two fundamental processes: photocatalysis and superhydrophilicity.
Over time, building facades become dirty and full of contaminating agents that are carried through the air to the surface. When the surface enters into contact with sunlight (or some LED lights), titanium dioxide particles are activated which use light energy to transform the moisture in the air into oxidizing agents which destroy the nitrogen dioxide particles and contaminating agents and transform them into water vapor and salt.
This process, which is known as PHOTOCATALYSIS, is repeated millions of times per second until all contaminants are destroyed, meaning the surface is constantly being self-cleaned. SUPERHYDROPHILICITY is produced to complete the treatment action. Thanks to the properties of NEOLITH® + Pureti facades, water expands on the surface evenly when it rains to drag and remove any remaining dirt particles. This leaves the surface completely clean without any water marks.
