Pureti, turning cities into forests

Pureti, the treatment against pollution

Together for a more sustainable city

Cities are responsible for 75% of all the world's carbon emissions. But when a city's impact is big, it is also where the big changes can happen.

Air pollution poses serious risks to human health, especially in terms of long-term exposure. According to WHO, 53% of the world's population lives in cities where outdoor air quality is below their guidelines, which is concerning considering that 90% of the world's cities have unsafe levels of air pollution and outdoor air quality.

Improving the standard of living and quality of life for all residents is critical for these cities to support future growth. Air quality that meets national standards improves human health and environmental quality of life.

The good news is that there are many ways to make a city greener and thus reduce CO₂ levels. And this task does not fall to politicians alone, the fight against climate change is a joint task.

What is Pureti?

Pureti is a range of solutions for continuous purification of both outdoor and indoor environment.

It decomposes and eliminates dirt, bad odors, bacteria and other contaminants in the presence of light, thus improving air quality and reducing maintenance costs.

Pureti, of American origin, is a treatment based on photocatalysis, composed of water and titanium dioxide nanoparticles. It is applied by micro nebulization on all types of surfaces in a safe way.

It is a highly adhesive and transparent solution, which differentiates it from other photocatalytic products, capable of purifying the air and eliminating pollutants from the environment by itself, only with exposure to light.

A global innovation

At Salvi Lighting we have a close commitment to the environment and people's health.

Thanks to the Pureti coating, our luminaires are able to clean and purify the air through photocatalysis, eliminating pollutants such as NOx, Sox and VOCs. The luminaires obtain a self-cleaning and mold-reducing effect, saving time, money, water, chemicals and energy in maintenance.

The luminaires are coated with titanium dioxide nanoparticles (TiTO2) and when UV rays hit them, a chemical process begins that converts oxygen and water vapor into OH and O2 cleaning agents. OH converts organic dirt and volatile organic compounds into mineral and gas, and back to H₂O. On the other hand, O2 reduces nitrogen oxide (NoX), one of the most harmful gases present in the atmosphere, to relatively harmless nitrates. This process is repeated millions of times, reducing nitrogen dioxide levels by about 55% in laboratory tests.

Tests have been carried out on our SIL solar luminaire to see the effect of this treatment. The result obtained is shown in the image.
