The Validated Solution
Aerobiotix independently tested and validated product at the Center for Microbial Community Systems and Health Research at the Research Triangle Institute. RTI is fully accredited and recognized worldwide as a leader in the evaluation of aerobiological technologies and is a primary air unit testing contractor to the US government, including the EPA and biodefense agencies.
In a controlled laboratory setting, a single pass through the device, running at standard 450 cubic feet of air per minute, the Aerobiotix system inactivated:
- 100% of Viruses (MS2 Virus)
- 99.97% of Bacteria (Staphylococcus epidermidis)
- 99.91% of Spores (Bacillus atrophaeus)
Combined UV-C and HEPA in-room air treatment and reduces viable airborne particles in the operating room setting.
Air samples were taken in two locations in an urban midwestern USA hospital setting. The location used was a 5 x 6m active general surgical operating room with standard positive-pressure ventilation. The sampling locations were immediately behind the sterile instrument table. Samples were taken with the C-UVC device in place, but turned off, and then repeated after 30 minutes of the C-UVC device running. In each test modality, air samples were taken every 60 seconds, until the detected particle levels reached a stable equilibrium. Samples were taken in two groups: operating room active baseline, operating room active after 30 minutes use of C-UVC unit.
Objective. To evaluate the effectiveness of a novel in-room air disinfection technology through the use of real-time viable airborne particulate counting.
Methods. Using laser particle fluorescence techniques in real time, airborne viable particle concentrations were obtained before and after air treatment with the in-room C-UVC device (Aerobiotix Tower One) in an active hospital operating room setting.
Results. A large number of viable airborne particles were found in the active positive-pressure operating room setting, with an average of 18628 viable particles per cubic meter in the 1.0-10.0 um diameter range. Thirty minutes after activation of the C-UVC device, the number was reduced to 914 viable particles per cubic meter in the same size range. Reductions were consistent across the particle sizes.
Conclusion. The C-UVC device, when employed as an in-room recirculation unit, provides significant reduction in airborne viable particle levels in a hospital environmental setting. The use of laser fluorescence-based techniques to track airborne viable particulate counts is a valuable tool for the rapid assessment of airborne bioload and the evaluation of air germicidal technologies.
