Biologically Safe Water Filters

Many acute dialysis units struggle to keep their portable RO/DI water supply for dialysis machines from exceeding the AAMI endotoxin standards.

Special considerations for acute hemodialysis have been issued.  You can find these standards at the following link ANSI/AAMI RD52:2004 Dialysate for hemodialyzers . The following are found under amendment 3 - Annex E.

E.2 Fluid Quality: suggests achieving higher fluid quality by passing final dialysate through a bacteria-and endotoxin-retentive filter.

E.3.7 Endotoxin-retentive filters: recommends in-line dialysate filters as a final barrier against contamination of the dialysate.

E.4 Microbial control strategies: “Consideration should be given to installing an in-line dialysate filter in the dialysis machine, if the machine manufacturer allows that option.”

The Nephros DSU contains a .005 micron membrane which eliminates bacteria, viral agents, cysts, fungi and biological endotoxins.  The DSU will produce ultrapure water when used post RO/DI.

One “Superbug” can cost a hospital $60,000.  Researchers at Duke University found that patients required more than 3 weeks of additional hospitalization after acquiring an infection while in the hospital.

The study suggests hospital administrators and infection control personnel should use these costs to design and evaluate specific preventative interventions.

The Nephros DSU (Dual Stage Ultrafilter) is designed to filter water used in ICU’s, burn units, etc.  This .005 micron filter will eliminatea variety of bacteria, parasites and fungi.
