Nephros CEO: Water Safety Market Is Broadening Beyond Legionella

Banks framed the shift as a structural change for Nephros, which sells water purification systems to hospitals, dialysis clinics, commercial buildings, laboratories and food-service operations. The company's pitch is that water-quality failures can shut down buildings, damage equipment and erode patient trust.

"Today's event isn't really about filters, it's about water," he said.

Nephros shares trade thinly on the OTC market. The company has been working to expand beyond its core hospital filtration business into broader commercial and institutional settings, where water-safety regulations are tightening in several U.S. states.

CFO Judy Krandel also spoke at the event, which was webcast Tuesday afternoon. The company has not yet provided updated financial guidance for the current quarter.
