Filter Performance

Efficacy of Point-of-Use Nephros Filter in Removing Nosocomial Infection-Associated Waterborne Pathogens
The presence of waterborne pathogens in hospital water systems has been epidemiologically linked to nosocomial infections in Intensive Care Units (ICUs). These pathogens include Legionella, Pseudomonas, Stenotrophomonas, Acinetobacter, Klebsiella, and
Mycobacterium species.

Dual Stage Water FIlters : Two Metropolitan Hospitals Eliminate Legionella:
A major cause of hospital acquired infections is water borne pathogens. Current methods to eliminate these pathogens involve complete chemical or heat disinfection of the entire hospital water system.

POINT‐OF‐USE WATER FILTRATION-Preventive efficacy and cost‐effectiveness of point‐ot‐use filtration in a subacute care unit.
Holmes C, Cervia JS, Ortolano GA, Canonica FP. South Coast Medical Center, Laguna Beach, CA.
Infections with Pseudomonas aeruginosa and other waterborne pathogens (WBPs) are major contributors to serious morbidity and mortality in hospitals. We sought to determine whether point‐of‐use (POU) water filtration might result in decreased risk of infection in the subacute care unit (SACU) of a 208‐bed medical center. Our findings indicate that POU water filtration can significantly and cost‐effectively reduce colonization of and infection with WBPs, including ventilator‐associated pneumonia, in an SACU.

Pseudomonas

Danger on Tap in Hospitals
LITTLE ROCK, ARK—Hospital water is one of the most frequently overlooked sources of nosocomial infection—and is potentially one of the most easily controlled. After analyzing the available data, Elias J. Anaissie, MD, Professor of Medicine at the University of Arkansas for Medical Sciences in Little Rock, and colleagues concluded that high-risk patients should avoid exposure to hospital water altogether and use sterile water instead
