The problem
In an ambulance, a hospital room, a laboratory or a farm, aerosols build up and pathogens pass from one patient, worker or animal to the next. Disinfecting surfaces or filtering outdoor air is not enough. While a space is occupied, the risk of indoor airborne transmission remains.
Emission
1,000+
particles per minute
with potential viral load, released when an infected person speaks loudly.
Dispersion
15 meters
of possible airborne transmission
of SARS-CoV-2 in enclosed spaces, especially with poor ventilation.
Persistence
3 hours
of viability in aerosols
SARS-CoV-2 can remain infectious in the air for at least this long under experimental conditions.
The space has to be cleared. They can't be used with people inside. They generate waste.
They need long exposure times. Use is limited with people inside.
They trap particles but don't inactivate microorganisms. They need powerful fans, make noise, use more energy and generate waste.
Kirion solves all of this at once.
The solution

Active biosecurity during transport, not just between calls. Less bioburden in the patient compartment and less turnaround time between patients. Protection for crews.
Lower risk of cross-contamination in BSL-2 rooms and laminar flow cabinets, with no vibration or chemicals to interfere with testing.
Patient rooms, exam rooms and waiting rooms with continuously treated air and no noise for patients or staff.

Keeps semen dose and genetics labs negative for PRRS and bacteria by treating the air continuously while staff work.
Protects boars, sows and piglets with the animals inside, and shortens quarantine and acclimation.
Reduces the risk of infection during stops and transport, continuously protecting the entire breeding cycle with no chemicals or noise.
How it works
A controlled electrical discharge turns air into cold plasma, which eliminates viruses and bacteria as it passes through the unit.
Simulation · Kirion
The three stages, one by one
Loading the 3D simulation…
A small electrical discharge moves air through the unit with no fan or moving parts. That's why it makes no noise.
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.
In the final stage, the catalyst transforms the residual molecules, releasing clean air that is safe for people and animals.
