Can Ozone kill COVID-19?

COVID-19 Virus

Introduction

Since ozone has been proven to kill 99.9 percent of pathogens in the air, including SARS Coronavirus and influenzas such as H5N1, researchers anticipate that it may be an important tool in preventing the spread of the Coronavirus Disease 2019 (COVID-19). This 2019 strand has a similar makeup to SARS. Therefore, we anticipate that ozone may inactivate the new, stronger strand, COVID-19.

For decades, we have seen that ozone is a safe and cost-effective option for protecting people by inactivating dangerous viruses and other pathogenic threats.

Ozone destroys viruses by attacking the nucleic acid core, thus damaging the viral RNA. This can result in the virus's failure to attach to normal, healthy cells, and the breakdown of the single-stranded RNA can lead to the destruction of the virus.

The recent COVID-19 pandemic has resulted in a renewed interest in the use of ozone to inactivate viruses. In the study “ Inactivation of Surface Viruses by Gaseous Ozone” its authors Chunchieh Tseng and Chihshan Li show the efficacy of ozone is related to the type of virud, the ozone concentration (C) and exposure time (T). This is known as the CT product.

Importantly, they also state that the ozone dose required for airborne viruses is much lower than for surface viruses.

Ozone has been widely used for disinfection, sterilization, deodorization and disintoxication thanks to the following characteristics:

Full coverage

Ozone gas created by our ozone generators release the ozone in the air for disinfection of airborne droplets or for disinfecting surfaces like key boards. They can reach every corner of the environment, leaving no place unsterilized. It is known that microorganisms can grow in crevices. UV methods to inactivate surface viruses can not completely penetrate these hidden areas or illuminate behind the UV shadow. Ozone however may penetrate these areas.

Convenience

Ozone is produced by simple equipment. Our products, large or small in ozone production capacity, can be used in homes, a single room, a large office, medical centres, hospitals, warehouses, factories, public spaces or public transportation modes such as buses, taxis and the trains. We can customise our products to meet customer specific requirements like Mobile ozone disinfection equipment.

High Efficacy

Ozone is an FDA and EPA approved 100% natural and safe sanitiser for aqueous and gaseous environments. Researchers found that the novel coronavirus is 80% similar to the SARS virus in their genome sequences. It is reasonable to predict that ozone is equally effective in preventing and controlling the new coronavirus.

Here is a list of some relevant research papers:

Gaseous Ozone Risks

Breathing large amounts of ozone can be harmful. Symptoms include coughing, shortness of breath and ultimate damage of the alveoli. Note that unlike chlorine nobody has ever died form an ozone overdose.

Exposure to ozone in the workplace is controlled by the Occupational Safety and Health Administration and their counterparts around the world. Fortunately our nose is very sensitive to ozone, we can smell a slight whiff of ozone at a 0.01 ppm. This is ten times lower that the OSH limit of 0.1ppm for an 8 hour working day. Exposure to ozone in the workplace is controlled by the Occupational Safety and Health Administration and their counterparts around the world. For most of our ozone generators we can hook up an ambient ozone monitor to adjust the ozone dose so that the OSH safe ozone levels are alway met.

Here are some of our popular products to disinfect the air, surfaces and your hands:

Disclaimer: To our knowledge no studies on the efficacy of ozone to inactivate the COVID-19 virus have yet been published. The information on this blog post is for informational purposes only and should not be seen as any kind of advice to inactivate the CIVID-19 virus with any of our ozone products.

odourBoy

A versatile ozone machine suitable for 24/7 operation in offices, waiting rooms, receptions etc with human occupation. This machine produces a low ozone dose keeping within the OSH limits.

odourBoy

odourMate

A portable ozone machine producing a high ozone concentration. This machine should be used with a timer to 'power' disinfect a large space with no humans present. After the treatment and the ozone is dissipated humans can enter again.

odourMate-310

QLC-Series

The QLC machines are commercial machines and produce a very high ozone concentration aimed at the larger spaces. The machines have a built-in PLC, ozone output control, timers and can be interfaced with ozone sensors to control the ozone to a safe level. A common application would be to ozonate a factory area during working hours at a low dose and "power" disinfect for pathogens, molds etc after hours.

QLC-Series

The Ozone Tap

This faucet produces ozonised water which disinfects your hands. You can also fill a spray bottle with it and disinfect surfaces. This faucet performs many disinfection tasks including hand washing, fruit and vegetable washing,meat and seafood washing. It kills bacteria, removes odours, removes pesticides and keeps food fresh.
