innowave 240/270® Evaluation of Microbial Removal/Inactivation University of Arizona • Renowned for Department of Soil, Water and Environmental Science • Dr. Gerba is one of the leading microbiologists in the country - he authored the current EPA standards for municipal drinking water • "Open checkbook" for testing the innowave 240/270® against any known microbiological contaminant found in US water systems today • "High road approach" - most complete testing ever done on any water purifier

US EPA Criteria System must meet or exceed US EPA's test standards for Microbiological Purifiers: • Water treatment units or devices designed for the protection of human health must be effective against pathogenic microorganisms • System must be able to provide this capability over the designed operational life of the equipment • Any microbiological water purifier must be capable of removing or killing enteric bacteria, viruses and protozoan parasites • System must be capable of reducing "challenge" levels in each class of microorganisms

Test Parameters • innowave 240/270® systems were tested against the US EPA Guide Standard and Protocol for Testing Microbiological Water Purifiers • Both tap water and "worst" water were used in the tests • System tested for removal/inactivation of poliovirus, rotavirus, Cryptosporidium oocysts, and klebsiella terrigena

Goal #1 Demonstrate the system's ability to meet the US EPA Guide Standard and Protocol for Testing Microbiological Water Purifiers: • Klebsiella terrigena • Poliovirus type 1 • rotavirus SA-11 • Cryptosporidium parvum oocysts

Goal #2 To evaluate system's ability to reduce or inactivate waterborne pathogens: • Escherichia coli • Salmonella typhimurium • Shigella dysentariae • Vibrio cholera • Yersenia enterocolitica • Hepatitis A virus • Adenovirus • Mycobacterium fortuitum • Campylobacter jejuni

Results In all cases, the innowave 240/270® exceeded US EPA removal parameter levels of: • 99.9999% for Bacteria • 99.99% for Viruses • 99.9% for Parasites The University of Arizona Study confirmed that the innowave 240/270® - • Meets microbial removal standards as required by US EPA, which far exceeds even NSF requirements • Is capable of removing all major waterborne disease-causing bacteria from water • Removes Hepatitis A virus, one of the most heat resistant enteric viruses

Conclusion • Most extensively tested system in US for microbiological contaminants • Tests by multiple laboratories have proven the innowave 240/270® to be effective in reducing harmful contaminants • Distillation is clearly the most effective method to consistently clean water today
