Disinfecting air with people or animals inside takes a different technology.
Kirion uses cold plasma generated by ionic wind. It eliminates viruses and bacteria as air passes through, with no chemicals, no filters and no noise.
How it works
Three steps, less than a second.

The real unit, piece by piece
Loading the 3D simulation…
Air enters.
A small electrical discharge moves air through the unit with no fan or moving parts. That's why it makes no noise.
Air turns into plasma and germs are eliminated.
That same discharge generates cold plasma from the gases in the air, producing reactive species (O₃, NO₂ and others) that are lethal to viruses, bacteria and other microorganisms, reducing their ability to infect. All of this happens in less than a second, during a single pass through the unit.
Clean air comes out.
In the final stage, the catalyst transforms the residual molecules, releasing clean air that is safe for people and animals.

Cedrion technology
Born in the aerospace industry.
Kirion applies Cedrion's ionic wind to biosecurity, the same technology that cools electronics in aeronautics and mobility. Cedrion was founded in Madrid in 2017, was incubated at ESA BIC and protects the technology with 3 patents.
