Continuously Reduce Overall Bioburden by 70%+ with Indigo-Clean

Clinical testing has shown Indigo-Clean can achieve a continuous 70+ percent reduction of harmful bacteria in the environment. At the same time, recently published studies show that improved environmental hygiene compliance can reduce HAI rates by up to 32% for certain organisms.1

These results, combined with the additional cost per patient due to HAI, suggest that preventing even a single infection would create a positive ROI and drive down costs for healthcare providers.


Indigo-Clean is currently being evaluated by several institutions across the U.S. including Froedtert & the Medical College of Wisconsin Froedtert Hospital in Milwaukee, WI.

The initial study at the Hospital involved a 34'×10' waiting area in the Gastroenterology (GI) Diagnostic clinic and used a very low level of disinfecting light from only two Indigo-CleanTM fixtures: one blended white and one Indigo-only. This allowed the team to evaluate the level of disinfection at various times of the day throughout the room. Over 1,000 samples were collected and analyzed during a four-week period. The results from this study were consistent with those from the University of Strathclyde conducted at the Glasgow Royal Infirmary (Glasgow, Scotland).2,3,4

Additional clinical partnerships with other hospitals created through our Clinical Partners Program are in process.
