“The conclusion is that in the form of droplets on exposed surfaces, IonFlow technology has a clear inhibition on viral entry.”

LightAir IonFlow fights the  
spread of COVID-19 

  • Swedish virus inhibitor demonstrates virus destruction 
  • Scientifically and independently proven on viruses in the air and on surfaces
  • Well-established technology with over 250,000 units sold
LightAir IonFlow virus inhibitor is scientifically and independently proven on viruses in the air and on surfaces, and together with the development of vaccines, can actively contribute to halting the spread of COVID-19.

New tests from a leading European research institute, IrsiCaixa, show that LightAir’s IonFlow technology destroys engineered SARS-CoV-1 and SARS-CoV-2 viruses in drop form on surfaces. This additional evidence extends the earlier findings of a seven-year scientific study from Karolinska Institute, which showed the technology’s effectiveness against aerosols and how it destroys airborne viruses and greatly reduces the spread of infections.

The new tests measured out various versions of engineered viruses – pseudoviruses – that mimic the entry of specific corona viruses into cells. The conclusion is that IonFlow technology has a clear inhibition on viral entry when viruses are present in droplet form on exposed surfaces. The ultrahigh-density ionization process attacks the protective protein shell of the virus, thus neutralizing it: preventing it from attaching to, and infecting, human cells.

“IonFlow continuously attacks the virus in the air and on surfaces, while destroying its infectious capabilities. It is great that we now have supplemented the previous in-depth study from the Karolinska Institute, which so clearly shows how our technology prevents the spread of a number of viruses,” says Lars Liljeholm, CEO of LightAir. “Providing pharmaceutical treatments and creating vaccines is important. But it’s not only about that. Innovative technology is also clearly a part of any answer to pandemic viruses. We’re proud to provide a proven solution for reducing infections in offices, schools, homes and other shared spaces.”

Currently, more than 250,000 IonFlow units have been installed globally. A single unit generates approximately 30 billion electrons per second, which transform into negative ions when they meet oxygen molecules in the air. This electron production results in a concentration of more than 19 million negative ions per cm3, sufficient to continuously disinfect about 50m2 of indoor space.


We’re fighting COVID-19, in the air and on the ground.

Scientific tests shows that LightAir IonFlow air purifiers destroy virus while they’re still in the air and on surfaces. With this product you disinfect your home, office, school or other facilities from unwelcome viruses.


LightAir Health+ is an innovative solution for air purification that consists of two complementary technologies.
“The virus inhibition provided by LightAir IonFlow, in combination with the medical-grade air purification of the LightAir CellFlow, creates an unbeatable path for a responsible re-opening of offices and schools,” says Rob Jansen, founder and CEO of Habitat Solution, distributor of LightAir in the Benelux region. 

How COVID-19 spreads

COVID-19 can quickly spread between people, especially indoors and in poorly ventilated spaces. When an infected person coughs, sneezes or speaks, millions of invisible virus particles are released into the surroundings via respiratory droplets, where they can remain infectious for a long time. 

While the larger droplets settle on all nearby surfaces, smaller droplets might stay suspended for up to 20 minutes in the air or up to 48 hours on indoor surfaces. People can catch COVID-19 when these infected droplets get into their mouth, nose or eyes.
