The Inline PureFlow® Blue is an inline cartridge built around a 0.08 μm hollow-fiber ultrafiltration membrane. Unlike traditional chemical treatment systems, it introduces no disinfectants, no iodine, and no continuously released antimicrobial agents into the treatment water. Instead, it provides a physical bacterial barrier supported by ASTM F838-certified Log 10 bacterial reduction (99.99999999%).

EPA WaterSense-certified filters are becoming increasingly important across healthcare, hospitality, and senior living as water-efficiency requirements expand across the US, especially on the West Coast, where several states now require WaterSense-level standards by law.

Every summer, the same conditions repeat across commercial buildings, hotels, healthcare facilities, and residential properties across the US. The reported incidence of Legionnaires' disease in the United States increased between 2000 and 2018. That trajectory is not coincidental. It tracks closely with the seasonal and environmental patterns that summer creates in built water systems.
