ViroForce Research Facilities
The virology research is presently performed in laboratory facilities used initially by two highly successful biotech companies – QLT and ID Biomedical. Dr. Mike Noble, a Professor of Medical Microbiology at UBC, hospital infection control consultant, and Director of the CMPT program (National Microbiology Lab Quality Control Program), has confirmed it is safe for the virology and bacteria research to be conducted there, as the lab has good ventilation with a large fume hood.

Virus Research
The research undertaken by Dr. Hudson has conclusively proven that ozone will kill up to 99.9 of all known viruses on various hard surfaces normally found in hospitals, cruise ship and hotel rooms. Ozone will kill 99% of each of these viruses on typical surfaces found in hospitals, cruiseships and hotel rooms:

Some viruses were vulnerable to ozone gas in the dried state, while others required the use of critical humidity levels.

Bacteria and Fungi Research
In addition, all the bacteria and fungi tested can be killed under similar conditions to that used to kill the viruses. Below, you can view test results for Klebsiella Bacterium and Aureobasidium Fungus.

Dr. Hudson’s Research Conclusions
"Based on these results we conclude that the viruses tested are efficiently inactivated by gaseous ozone, on each of the surfaces tested, under conditions relevant to practical applications. We believe that ozone gas also has potential as a safe antiviral and anti-microbial agent in various other situations that are accessible to a small, portable, ozone generating machine.” Dr. Hudson has written a comprehensive report which summarizes his results obtained over the preceding two and half years. This has been sent to the BC Center for Disease Control for evaluation and received very positive feedback (see next section). The most recent research by Dr. Hudson indicates the ViroForce technology will also kill C.difficile and MSRA.

Dr. Petric – Centre for Disease Control Validation
A detailed report by Dr. Petric PhD, FCCM of the Vancouver Center for Disease Control, examined Dr. Hudson’s research report findings on May 15th 2006, and concluded in part: “Overall, the investigations performed at ViroForce Systems Inc. on the inactivation of viruses showed that O3 especially at elevated humidity is an effective agent for inactivation of structurally diverse viruses on dried on surfaces such as would be expected to occur in environmental contamination.   The inactivation studies in field settings generated findings consistent with those obtained in the controlled laboratory setting.  The O3 from the ViroForce generator was produced in adequate amounts to maintain a sufficient concentration to be effective in field setting.  The studies were well designed from a scientific perspective and focused on the primary aim of proving that O3 is an effective agent for virus inactivation.”
