Is your device effective against SARS-CoV-2 (COVID-19)?05.02.2021

The Respiray wearable air purifier has passed successful tests with alphavirus, that is a similar single-stranded RNA-genome virus to SARS-CoV-2 and both viruses are comparable in size: approximately 70-100 nanometers. There are many studies that show how coronavirus acts similar to other viruses and bacteria that UV-C light successfully inactivates.

A large amount of research has shown that UV-C is extremely effective since it inactivates pathogens in different ways. For example, for all known coronaviruses it has been shown that UV-C breaks the RNA chains rendering the virus unable to reproduce. It also disintegrates the membrane of the coronavirus virion and on top of it all breaks the structure of the famous spike proteins of the coronavirus. UV-C LED manufacturer Crystal IS, whose LEDs our device uses, presents research that demonstrates the effectiveness of germicidal UVC LEDs against SARS-CoV-2.

Another UV-C LED manufacturer has run tests comparing necessary light intensities to inactivate 99.9% pathogens and found that a similar UV-C light dose was needed to inactivate both E. Coli bacteria and SARS-CoV-2 at 265 nm. Further tests have also shown that UV-C light is effective at inactivating SARS-CoV-2 (COVID-19).

The effectiveness of our disinfection module has been independently tested for S. aureus and E. coli bacteria, resulting in around 2.5 and 2.6 log reduction respectively (99.68% and 99.89%) at 30 l/min throughputs. Our device has two of these disinfection modules built-in.

Please note: Respiray’s air purifier is not medical-grade Personal Protective Equipment (PPE), and in circumstances where medical-grade Personal Protective Equipment is recommended, you should consult a health care professional. Please remember that the use of our wearable air purifier does not replace the recommended measures to stop the spread of COVID-19. Follow the latest guidelines and rules of your local authorities and health care professionals.
