Dialysis Water

Because dialysis patients are exposed to hundreds of liters of water each week during treatment, even small amounts of contamination can pose serious risks. Dialysis-quality water is essential for protecting patient safety and supporting consistent treatment outcomes. Dialysis providers must meet strict water quality standards while managing complex treatment infrastructure that includes pretreatment, reverse osmosis, and distribution loops. Within these systems, filtration plays an important role in microbiological control and helping facilities deliver dependable water purity throughout the dialysis process.

Nephros dialysis filtration solutions assist in preparing water used for bicarbonate concentrate and dialysate production. Our filters use hollow-fiber membrane technology with a 5 nanometer (0.005 micron) pore size to retain bacteria, viruses, and endotoxins through size exclusion. Nephros DSU-D, SSU-D, SSUmini, and EndoPur dialysis filters are FDA 510(k)-cleared as Class II medical devices and support compliance with the hemodialysis water quality requirements defined in ANSI/AAMI/ISO 23500-5:2019.

Protect Patient Dialysis Water Quality

During dialysis treatment, consistent water purity across complex treatment infrastructure is an ongoing operational priority. Even well-managed pretreatment, reverse osmosis, and distribution loops can experience variability that introduces microbiological risk into the dialysis process. Dialysis teams therefore rely on layered safeguards to protect treatment integrity and patient safety.

Incoming water may contain biological contaminants such as bacteria, viruses, and endotoxins, as well as chemical hazards like chloramines. Exposure to these contaminants can lead to serious complications, including chronic inflammation, infection, hemolytic anemia, or septic reactions. Protecting dialysis water purity therefore requires multiple layers of purification and continuous monitoring.

Dialysis filtration provides an additional safeguard within these systems by removing microbiological contaminants before water enters dialysis equipment. Whether integrated into portable RO/DI equipment or installed within centralized water systems, dialysis filters help support dependable water purity and reliable preparation of dialysate that meets AAMI standards.
