Before we could bring our NoviSphere PE 254 pathogen-eradication system to market, we felt it was critical to validate its effectiveness – particularly its ability to kill coronaviruses. To do this, we tapped researchers from the University of Minnesota with expertise in pathogens and aerosol science to test the unit’s efficacy against a COVID-19 surrogate strain.

The university team’s findings were written up in the article available for download below, which is currently available for review and feedback by readers of the American Chemical Society’s Environmental Science & Technology. Only a small fraction of the papers submitted to the journal successfully complete the peer-review process and are published. Underscoring the importance and validity of its research and findings, the U of M article is slated to appear in an upcoming issue of ES&T.

Due to the urgency of the current coronavirus pandemic and relevance of this work, we have a rare opportunity to make the article available, so that you can read for yourself the research team’s methodology and results. Key points include:

  • Coronaviruses, including SARS-CoV-2, the strain that causes COVID-19, can remain present in an aerosol at room temperatures for an extended period
  • Technologies are needed that can directly mitigate survival of infectious viruses in aerosol form
  • Ultraviolet germicidal irradiation at wavelengths of 100-280nm (UV-C light) has been known for many decades to be effective at preventing transmission of airborne diseases, offering promise for eliminating coronaviruses
  • The NoviSphere prototype incorporated monochromatic 254nm UV-C light with a ducted design
  • Using a custom wind tunnel built for this research, the U of M team tested the prototype’s ability to kill a surrogate for SARS-CoV-2 – a porcine respiratory coronavirus (PRCV)

The full study provides details regarding the system’s performance in efficiently inactivating aerosol coronaviruses. Most notably, the researchers found that zero viable virus particulate survived passing through the prototype NoviSphere PE-254 unit, thus validating our system to be 99.99% effective.

This means you can install the system in your environment with full confidence that it will help keep those around you safe by continuously delivering clean, breathable air.
