Is the corona virus air borne?

Up for debate:
Is the coronavirus behind covid-19 air borne or not?

Experts have agreed that the coronavirus behind COVID-19 spreads through direct contact and large droplets that, once sneezed or coughed out, often fall harmlessly to the ground. There are however now a large number of scientist around the world who strongly believe the virus to be spread by airborne transmission and then lingering in the air for hours within tiny micro droplets. Below we have gathered some very interesting supporting links for those of you who want to know more.

Can LightAir prevent spread of corona virus?

LightAir have not yet been able to test if our air purifiers prevent spread of covid-19. We have reached out to several scientist and test institutes, but they are understanably all occupied. If you have the ability to help us out in this matter please reach out as soon as possible.

What we do know

All LightAir air purifiers are all tested and approved to effectively remove certain air borne viruses. Of all the viruses tested so far,  such as influenza-, rota- and calici virus, we achieve at least 97% removal rate.

The IonFlow products are, as far as we know, the only air purifiers in the world that have been tested, proven and peer-reviewed by the international scientific community. A 7 year long study was carried out by well known scientist at Karolinska Institute, one of the foremost medical universities in the world and awarder of the Nobel Prize in Medicine, and published in Nature Scientific Reports, the world’s most highly cited scientific journal.

IonFlow 2.0 Evolution

Deactivates 97% of certain viruses

LightAir IonFlow technology is scientifically proven to deactivate more than 97% of viruses in the air! The viruses are made harmless immediately in the air as the negative ions attach to them making sure they will never bother you.

The study included animal study. It showed that none of the animals got sick when exposed to the virus when the IonFlow air purifier was on while 75% got sick when the air purifier was turned off. In real-life, this would mean that LightAir IonFlow air purifiers would prevent or minimize the risk for you, your family and colleagues getting sick.

The following viruses was included in the study, which all have a huge effect on induvidual health as well as on society:

  • Influenza virus
  • Calici virus (winter vomiting disease)
  • Rota virus (diarrhea)


LightAir air purifiers were developed with the outset of removing the finest and most harmful particles. According to third-party governmental tests, LightAir air purifiers from both CellFlow and IonFlow technology, can effectively remove several different viruses that you want to avoid to stay healthy. Tests has been conducted on H1N1 (swine flu), calicivirus, rotavirus and influenza virus (H3N2).


This is for the sensitive.

LightAir air purifiers must be considered the best and most efficient air purifiers for allergy, asthma, COPD, pregnant, infants, children, elderly and other people sensitive to influenza and other virus infections.

Are you one of the sensitive? We support some people every year who have a proven medical condition and will profit greatly from clean indoor air.

Size matters!
LightAir do it differently.

More than 90% of all particles in the air are smaller than PM0.1 (micron) and HEPA filter air purifiers can in best case only catch particles down to PM0.1, but not below. Viruses are extremely small particles, below PM0.05-0.003, and are impossible to catch in any affecting number with regular HEPA filter air purifiers. If a virus is caught in the HEPA filter it also stays alive and can be release into the air again. The IonFlow technology deactivates the infectivity of the virus already in the air, making sure they become harmless. The CellFlow technology removes the viruses and then deactivates them in the process. 


What about bacteria and other microbes?

LightAir has carried out successful testing on mold and bacteria. The tests show that LightAir air purifiers effectively reduce the concentration mold spores as well as inhibits the growth of mold. Laboratory tests have also proven that LightAir air purifiers effectively reduces the concentration of bacteria. LightAir is planning to further explore the effects on different microbes.
