Biologically Safe Water Filters

The Nephros dual-stage ultrafilter (DSU) is a .005 micron ultrafilter for endotoxin control.  The filter will last about one year under normal conditions, post RO/DI, in a dialysis setting.  The DSU can be disinfected in place.  It can be part of a portable RO/DI or a final filter just before the dialysis machine (i.e. at wall box) or part of the RO water or bicarbonate loop.

Dialysis machine manufacturers include a .02 micron filter as part of their equipment.  Some of these filters degrade rapidly when exposed to disinfectants such as bleach and ultrafiltration is lost.

Most machine filters have to be changed every 2-3 months.  The yearly cost of multiple filters, plus the time to change them out along with the potential for failing the .02 micron filtration, adds up to more than the cost of using the Nephros DSU.

Ultrapure water/dialysate has multiple benefits for the dialysis patient, and used effectively, it can also lower overall costs for the dialysis facility.
