What Nephros does
Nephros is a publicly traded water technology company (NASDAQ: NEPH) that develops, manufactures, and sells FDA-cleared ultrafiltration and microfiltration products for medical and commercial water purification markets. The company was founded in 1997 and is headquartered in South Orange, New Jersey, with 51-100 employees and FY2025 revenue of $18.8 million, representing 33% year-over-year growth. Its core technology is a proprietary 5-nanometer (0.005 micron) hollow-fiber membrane that achieves over 11-log bacteria reduction, 8-log virus reduction, and 5-log endotoxin reduction, with products holding FDA 510(k) Class II medical device clearance, ISO 13485:2016 certification, and MDSAP certification.
The product portfolio spans three primary verticals. Infection Control Filtration includes the S100 point-of-use microfilter family (0.1 micron, 90-day life) and DSU-H/SSU-H in-line ultrafilters (5 nanometer, 180-day life) for healthcare facilities and emergency response. Dialysis Water Filtration includes DSU-D, SSU-D, SSUmini, and EndoPur filters meeting AAMI/ISO 23500-5 standards with 12-month life, serving dialysis centers. Commercial Water Filtration covers the 14, 15, 30, 34, 35, 36, and 41 series for foodservice, hospitality, and beverage applications. Recent additions include the 19-Series PFAS Filter (launched October 2025), the 20-inch HydraGuard Ultrafilter for sterile processing, and the S100 In-Line Microfilter launched April 2025.
Nephros monetizes through direct hardware sales with recurring filter replacement cycles, professional services (Water Management Program consulting, Legionella certification, emergency response, ice machine audits), and educational programming through the Nephros Water Institute. The company employs a hybrid go-to-market combining an enterprise field sales force (doubled in 2022) for healthcare and dialysis accounts, an exclusive master distributor relationship with Donastar Enterprises for commercial food and hospitality channels, and a 24-hour emergency response capability. Customer base reached 1,600+ active sites by Q1 2025, gross margins are near 60%, and Nephros achieved its second consecutive year of positive net income in FY2025. Geographic expansion is underway into Puerto Rico (entered February 2026) and the Greater New York City region with a dedicated sales leader (April 2026).
