Test Comparsion Chart

The dose (irradiance) does not represent a minimum to attain a complete kill. It only represents a complete kill at the dose we chose to perform the test. The minimum dose for complete kill for all pathogens except the B. atrophaeus spore will most probably be lower (shifting the curves and points to the left). The Far-UV Sterilray™ Disinfection Wand achieved a log 4 reduction at less than 10 mj/cm² for Acinetobacter and MRSA and the noroviruses (FeCV). The C-diff spore is harder to kill per the blue line on the chart but still a very low dose is required to get a log 3 and log 4. We need additional data points to confirm this assumption. The avian flu and influenza virus should fall between the C-diff spore and the Acinetobacter bacteria. A log 3 to 4 reduction should take less than 1/2 second to achieve with the Far-UV Sterilray™ Disinfection Wand. Above tests performed Dec. 2006-Jan. 2007

Independent Testing of the Far-UV Sterilray™ Disinfection Wand

HEI has tested its patented Far-UV Sterilray™ disinfection system on a variety of organisms in several independent labs in the US and internationally. This data, combined with our expertise in using the Far-UV Sterilray™ Disinfection Wand to disinfect the noncritical high touch surfaces in hospital environments, is used to design room protocols and facility-wide service plans for our customers. These protocols — which include identifying greatest need, surfaces to treat, and number of treatments per day — are based upon the desired efficacy, the suspected organisms present, the number of areas being disinfected, and other variables such as the methods now being employed and the condition of the noncritical surfaces.
