Point-of-Use Water Filter

The Nephros 70-0289 S100 In-Line Microfilter is a point-of-use bacterial retention solution engineered for low-pressure water systems including sinks, eyewash stations, and ice machines. This 1/2in NPSM threaded filter delivers sterilizing-grade performance with a 0.1 micron polysulfone membrane that provides bacterial retention exceeding 109 CFU per ASTM F838-20 validation standards. The compact design measures 7 inches in length by 2.5 inches in depth with a 0.5 square meter membrane surface area, making it ideal for space-constrained installations. Operating at a maximum inlet pressure of 75 psi, the filter maintains a clean water flow rate of 2.5 GPM at 10 psi, ensuring adequate performance for typical sink and eyewash applications without compromising water delivery. The robust polysulfone membrane construction provides reliable contaminant removal while resisting common industrial water chemistry conditions. With a 90-day replacement cycle, the S100 offers cost-effective maintenance scheduling and straightforward cartridge changes. This microfilter is suitable for facilities requiring dependable bacterial control in compliance with safety standards for emergency eyewash and potable water applications. The threaded quick-connect design simplifies installation and replacement procedures, reducing downtime and service complexity across commercial and industrial environments.
