Indigo-Clean technology provides continuous environmental disinfection suited for a broad range of clinical applications and congregate settings. The technology works best where there is a concentration of patients, caregivers, students, staff or patrons who contribute to the migration of pathogens throughout the space. It is especially suited for entryways, waiting rooms, restrooms or places that are difficult to clean continuously, and/or where pathogens are known to enter the facility. Within the healthcare setting, it is also ideal for areas occupied by patients whose compromised immune systems make them more susceptible to acquiring an infection.
