Our technology disinfects the air at 99% through UV-C

Coupled with an LED lighting system, our Light Of Disinfection technology uses UV-C to disinfect the air in a closed environment.

Under the effect of UV-C, the DNA of these viruses is destroyed and viruses and bacteria are eliminated. Thus disinfected, the air then circulates in the room, guaranteeing a healthy and safe environment.

Even though UV-C has been used for over 50 years in hospital, medical and sanitization environments, our innovation resides in the ability to disinfect the air in a room in the presence of human beings with absolutely no danger to our health.

Air disinfection in the presence of human beings

Certified and approved by a French laboratory (Cofrac certified organization) and tested in P4 Laboratory. The only high security research laboratory (Biosafety Level 3 (P3/P4) laboratory) in France and in Europe to be able to :
– generate experimentally a higly contaminated, quantified, qualified and reproductible atmosphere
– conduct qualitative, quantitative and representative evaluations of an everyday environment in large volumes, to prove, in a reproductible way, the effectiveness and the performances of the decontamination technologies : UVC, filtration, photocatalysis…

The LOD has a defined disinfection effectiveness of Log 1 to Log 3. During air disinfection, the microorganism is “deactivated”. In other words, it is destroyed. Various levels of deactivation exist. These are often expressed in “Log” reduction:

  • Log 1 reduction = 90% deactivation 
  • Log 2 reduction = 99% deactivation
  • Log 3 reduction = 99.9% deactivation

The disinfection efficiency of the LOD can be up to 99%.

Our various solutions have been classified in risk group 0, i.e. with zero photobiological risk. There is no danger from the exposure of the user to the UV-C in the luminaire.

“By managing to disinfect the air in rooms in as people are there, we have won a great battle in returning to normal LIFE”

Olivier Moyen

His degree in biology engineering  and with his R&D team based in Lyon, they developed  an air disinfection solution using UV-C (Light Of Disinfection) coupled with a lighting device. He is therefore managing to master a technology  capable to disinfect the air in presence of human beings and at a very  accessible cost.. Manufactured near Nantes, LOD’AIR solutions are 100% French, certified and approved by a French laboratory.

What is UV-C?

UV-C is the most energetic short-wavelength ultraviolet light as well as the most harmful. In broad daylight, UV-C rays are hardly detectable. When it is very dark, they are part of the so-called black light rays.

UV-C is extremely energetic. This energy gives them a considerable power to alter biological molecules; they are used for their germicidal properties.

UV-C sends signals that break down viruses and bacteria through solar radiation.

The role of UV-C

UV-C is completely filtered out by the ozone layer in the atmosphere and therefore does not reach the earth’s surface. The wavelength of the ray makes it more or less harmful to the cells of bacteria and viruses.

The shortest ultra-violet rays are the UV-C  rays (between 200 and 280 nanometers) then UV-B and UV-A (280 and 400 nanometers). Recognized by scientists, UV-C rays have been used for more than 50 years in hospitals and clinics for the purification of drinking water in cities and in the food industry.

It makes it possible to destroy viruses on surfaces or that are suspended in air after sneezes or coughs.
