Urban air pollution is a serious problem in big cities as it exceeds the safety limits for human health in many cases. To this end, a directive has been passed in Europe whereby the EU must have reduced its greenhouse gas emissions by 80% by the year 2050, in comparison to the 1990 levels.

In response to this serious problem, Neolith has joined the environmental conservation efforts with the market launch of a revolutionary treatment for its SKYLINE facade line: PURETI.


What is Pureti?

Pureti treatment is an aqueous and titanium dioxide nanoparticle-based treatment that is sprayed on NEOLITH® to create a photocatalytic, self-cleaning and decontaminating effect, triggering the facades to continuously self-cleaning in addition to reducing the contaminating agents and, thus, improving air quality.


  • SELFCLEANING | facades due to the photocatalytic effect produced.
  • DECONTAMINATING | as substances that are harmful to the environment are neutralized.
  • ANTIBACTERIAL | as bacterial growth is stopped.
  • ANTI-ODOUR | as they completely eliminate bad organic odors.
  • ANTI-ALLERGEN | as the air we breathe is constantly purified and improved.

How does it work?

The Pureti technology creates self-cleaning surfaces that purify the air by means of two fundamental processes: photocatalysis and superhydrophilicity.
