The process in one diagram
Glossary in plain language
Every technical term used on this site, explained in one sentence.
Photocatalysis
A light driven process that breaks down organic compounds landing on a surface. The catalyst itself is not consumed.
Nanomesh
The transparent, 40 nanometre mineral layer PURETi leaves on the surface. Light activates it, and that is what makes the surface work for you.
MOM, Mineral Oxide Mix
PURETi's fourth generation raw material. It is why the system also works in visible light, and therefore indoors.
VOC
Volatile organic compound. A gas released by paints, furniture, cleaning products and other materials that degrades indoor air quality and can harm health over time.
NOx
Nitrogen oxides: urban air pollutants that come from traffic and combustion.
PM2.5
Very fine particulate matter, smaller than 2.5 microns. Small enough to reach the deepest part of the lungs.
Hydrophilic
Water loving. Water does not bead up, it spreads across the surface and carries the dirt away.
ATP
An indicator used to measure organic contamination. The lower the value, the cleaner the surface.
IAQ
Indoor air quality. It describes the air where people spend most of their day.
iSCAPE, Horizon 2020
The European Union research programme for reducing urban air pollution. PURETi was the winning technology of that programme.
Gold Edison Award
An international innovation award carrying Thomas Edison's name, one of the most prestigious recognitions in the industry.
ESG
Environmental, social and governance criteria that measure how responsibly a company operates. The European Union takes them increasingly seriously, and a PURETi treatment scores well here.
LEED
An international green building certification. A PURETi treatment can help earn points in it.
NASA Dual Use Technology
A technology that NASA also recognises as usable. PURETi is such a partner.
How big is 40 nanometres?
Zoom in
What we see with the naked eye
- Thickness of a sheet of paper100,000 nm
- Human hair70,000 nm
- Pollen25,000 nm
- PURETi layer40 nm
The green bar shows the same 40 nanometre layer at every step; only the magnification changes.
Hydrophilic surface
Outdoors, rain does this work for you.
More hydrophilic = more wetting = less dirt
