Do air purifiers kill viruses and help limit Covid-19 transmission?

Air purifiers can reduce airborne viral loads and are helpful as part of a layered approach to reduce coronavirus transmission.

As more researchers study the Coronavirus, it’s become clear that transmission is more likely to happen in crowded indoor areas than outdoors. As Dr. Linsey Marr of Virginia Tech in Blacksburg told the New York Times, “in poorly ventilated indoor settings, like most restaurants and bars, the virus can remain suspended in the air for long periods and travel distances beyond six feet.”

Can air purifiers such as OZONOS help?

In short, yes. Recent research by Japanese scientists has found that low levels of ozone, such as those generated by OZONOS air purifiers, can help reduce the transmission of Covid-19. An independent German laboratory has also confirmed that OZONOS air purifiers significantly reduce viral loads in test conditions.

How does ozone kill viruses?

Ozone can inactivate and destroy the virus by working as an oxidizing agent. There is evidence to suggest that when ozone reacts with the proteins and lipids in SARS-CoV-2 (aka, those crown-like spikes that surround the genome), it can destroy the structure of the virus and inhibit its ability to infect.

What are the limitations?

Since OZONOS is an air purifier, it doesn’t replace proper surface cleaning, hand washing and other public health recommendations. Running your air purifier is just one part of a layered strategy to lower the risk of transmission.

Other important ways to prevent Covid-19 transmission

Of course, clean air is just one defense in the battle against the Coronavirus. Do your part to flatten the curve by:

  • Following public health recommendations in terms of social distancing and keeping at least 6 feet apart from others in public areas.
  • Wearing a mask in public areas, especially where physical distancing is a challenge.
  • Cracking open a window. Experts have pointed out the importance of ventilation to help clear out aerosolized viruses.
  • Washing your hands often, with soap and warm water, for at least 20 seconds.
  • Using a hand sanitizer with at least 60% alcohol when hand washing isn’t an option.
  • Avoiding touching your eyes, nose and mouth.
  • Staying home if you feel ill, have symptoms (fever, cough, lack of smell, difficulty breathing) or have been in contact with someone presenting symptoms.

If you’re running a business, ensure everyone on your team understands the latest recommendations. “For cleaning protocols to be successful in a hospitality operation, they need to be clear to everyone, they need to be habitual and top-of-mind,” says CIRVIS hospitality expert Chris Glaessel.
