Manufacturer Narrative

Nephros s100 point of use is a sink water filter, class ii medical device that is placed on sink faucets in health care facilities in order to retain bacteria.The user facility routinely tests their water at their sinks and found that there was positive bacteria detected.A positive culture can be caused by improper installation, cross contamination and/or a breach of the filter membrane.Device evaluation: comprehensive review of the specific filter device history record and manufacturing inspections did not identify any product issues.The investigation of the returned filters determined that one of the internal filter components were damaged and ultimately allowed unfiltered water (with positive bacteria counts) to pass through the filter.Lot representative filter samples were tested for any signs of change in filter ability to function properly under the published product specifications.No changes or issues were identified.Active monitoring of customer plumbing systems identified pressures significantly above the product and plumbing specification.The root cause of the damage to the internal filter components was determined to be caused by excessive pressure and unusually poor water quality/conditions at the facility which stressed internal filter components above and beyond their recommended use.
