Nephros is a global medical device company that focuses on the development and commercialization of liquid purification filters that combine a best in class purification to flow rate ratio with filter endurance.

Nephros was founded in 1997, by healthcare professionals affiliated with Columbia University Medical Center, initially to address the needs of chronic renal failure patients.

The company has developed an alternative to current hemodialysis therapy known as Mid-dilution hemodiafiltration (mid-HDF). Nephros’ proprietary blood purification technologies enable mid-HDF to be offered to chronic renal failure patients. Nephros mid-dilution filters remove a range of harmful substances, specifically substances known as middle molecules, which have been linked to conditions such as carpal tunnel syndrome, dialysis related amyloidosis, and degenerative bone disease in chronic renal failure patients.

Nephros has extended its filtration technologies to meet the demand for liquid purification in other areas, in particular water purification. Today, Nephros ultrafilters remove biological contaminants from water and bicarbonate to provide ultrapure water and bicarbonate for use in dialysis. Nephros ultrafilters also purify water in the hospital/healthcare setting particularly at the point of use (i.e. at the end of the faucet or shower head). This approach has been shown to be particularly useful for infection control. Nephros is currently developing its filter technology in individual water purifiers for military applications.

Nephros has over 100 patents issued worldwide based on 15 different inventions which are primarily geared around our expertise as a filter development company, specializing in hollow fiber ultrafiltration membrane technology.
