Effectiveness of a novel ozone-based system for the rapid high-level disinfection of health care spaces and surfaces

Methods: Ozone gas at 50-500 ppm was combined with 3% hydrogen peroxide vapor in a test chamber and upscaled in rooms measuring 82 m3 and 90 m3 in area. Test organisms included methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococcus, Escherichia coli, Pseudomonas aeruginosa, Clostridium difficile, and Bacillus subtilis spores dried onto steel discs or cotton gauze pads.


Results: The combination of 80-ppm ozone with 1% hydrogen peroxide vapor achieved a very high level of disinfection, with a 6 log10 reduction in the bacteria and spores tested on steel discs and MRSA tested on cotton gauze during a 30- to 90-minute exposure. The entire system was scalable such that it achieved the same high level of disinfection in both the 81-m3 and 90-m3 rooms in 60-90 minutes.

AsepticSure Environmental Safety Report

A report produced by Walsh & Associates, a professional safety services company working in conjunction with the Analytical Services Unit of Queen’s University titled Report for Ozone Hydrogen Peroxide Industrial Hygiene Environmental Monitoring was commissioned.


The report, provided to the United States EPA, compared results to the following occupational exposure limits and environmental criteria: the Ontario Regulation respecting Control of Exposure to Biological or Chemical Agents (O. Reg. 833) TimeWeighted Average (TWA), ShortTerm Exposure Limit (STEL), and Excursion Limit; the U.S. Occupational Safety and Health Administration (OSHA) Permissible Exposure Limit TWA (PELTWA); the American Conference of Governmental Industrial Hygienists (ACGIH®) Threshold Limit Value TWA (TLV®TWA) and Excursion Limits; the Ontario Ambient Air Quality Criteria (AAQC); Health Canada’s published Lowest Observed Adverse Effect Level (LOAEL); and the U.S. Environmental Protection Agency (EPA) National Ambient Air Quality Standards (NAAQS).

The Report confirmed that the moment the door to the AsepticSure disinfected room was opened following the disinfection process the room was safe and immediately available for occupancy.

Canadian Infection Prevention and Control Conference


Queen’s University Professor Emeritus Dick Zoutman, MD, FRCPC by Poster Presentation reported on a C.difficile outbreak that began late November of 2014 on an acute care in-patient ward at Trenton Memorial Hospital, Ontario, Canada

Key Findings:

  • 4 infected patients on the 25-bed ward with one mortality
  • The outbreak was immediately contained following AsepticSure
  • The ward remained C.difficile free to the conference date
  • A time and cost comparison between conventional isolation room cleaning practices and AsepticSure found a time savings of 2 hours and 20 minutes over the four rooms in AsepticSure’s favor. Supply costs per room for AsepticSure were $3 per room, $7 for the manual method.



The Unique Superiority of AsepticSure® Disinfection

Facts and Conclusion

*          Using any other conventional double cleaning practices or disinfection technology it is simply not possible to achieve even a 3-log (99.9%) bactericidal and virucidal disinfection throughout the entire room. AsepticSure achieves disinfection. 


*          Recent time correlation studies demonstrated that isolation cleaning of 4 patient rooms with AsepticSure actually saved 2 hours and 20 minutes over conventional isolation room cleaning practices.
