The device description focuses on physical water purification processes (filtration, softening, carbon filters, reverse osmosis, deionization, UV sterilization, etc.) and standard monitoring/control components (pressure gauges, level switches, conductivity instruments). There is no mention of any software, algorithms, or data processing that would suggest the use of AI or ML. The "Mentions AI, DNN, or ML" section also explicitly states "Not Found".
No.
The device purifies water for dialysis and equipment, not directly treating a patient's medical condition.
No.
The device is a water purification system designed to remove contaminants from water used in hemodialysis and dialyzer reprocessing; it does not diagnose medical conditions.
No
The device description clearly outlines a physical water purification system with multiple hardware components including filters, pumps, tanks, and instruments. It is not solely software.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- Intended Use: The intended use is to purify water for use in hemodialysis, specifically for diluting dialysis concentrate, dialyzer reprocessing, and equipment rinse and disinfection. This is a process that prepares a substance (water) for use in a medical procedure, but it does not involve testing or analyzing a sample taken from the human body to provide diagnostic information.
- Device Description: The device description details a water purification system with various filtration and purification components. These components are designed to remove contaminants from water, not to analyze biological samples.
- Lack of IVD Characteristics: The description does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Detecting or measuring specific analytes in biological samples
- Providing diagnostic information about a patient's health status
In summary, this device is a water purification system used in the context of hemodialysis, which is a medical treatment. However, its function is to prepare a necessary component (purified water) for that treatment, not to perform diagnostic testing on a patient's biological sample.

Device Description
The PURE WATER Solutions' Water Purification System for Hemodialysis is designed to provide water of the required quality to meet AAMI standards for riohodialysto is actigate will remove organic, inorganic and microbial contaminants from the influent water supplied to Hemodialysis clinics. This system comes in various sizes to provide the proper volume of water for each individual clinic. It is easily used and maintained by clinic technicians.
The water treatment phase or pretreatment includes multi-media filtration to reduce suspended solids, water softening to reduce hardness and granular activated carbon filters to remove chlorine and chloramines. If finer filtration is required, cartridges with appropriate housings may be used.
The purifier phase includes reverse osmosis (RO) and or portable-exchange deionization (DI). The primary method will be reverse osmosis using an existing FDA cleared device. DI may be selected for use either independently or in conjunction with RO depending upon the influent water analysis, the available space and the demand required. If DI is selected, then 0.1 micron, absolute, final filters will be installed downstream of the DI and a temperaturecompensated, conductivity instrument will be used to monitor the quality.
The circulation phase or post treatment may consist of an RO storage tank with an appropriate 0.2 micron, absolute, vent filter, a stainless steel repressurization pump, ultraviolet sterilization, and 0.05 micron, absolute, final filter.
Auxiliary devices such as booster pumps, temperature blending valves, pressure gauges, sample ports, fittings, piping, level control switches and remote alarms are used as needed throughout the system.
A clean-in-place system consisting of an inert plastic or stainless steel pump and a solution tank is used to clean RO membranes. A paracetic acid disinfection product may be used to chemically disinfect the RO while ozone is used to disinfect the circulation phase.

§ 876.5665 Water purification system for hemodialysis.
(a)
Identification. A water purification system for hemodialysis is a device that is intended for use with a hemodialysis system and that is intended to remove organic and inorganic substances and microbial contaminants from water used to dilute dialysate concentrate to form dialysate. This generic type of device may include a water softener, sediment filter, carbon filter, and water distillation system.(b)
Classification. Class II (special controls). The device, when it is a water purification subsystem disinfectant, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 876.9.

A clean-in-place system consisting of an inert plastic or stainless steel pump and a solution tank is used to clean RO membranes. A paracetic acid disinfection product may be used to chemically disinfect the RO while ozone is used to disinfect the circulation phase.
All components used in the system are components with Safety and Effectiveness: existing safety records. Materials of construction consist of stainless steel, polypropylene, existing survey records. Water treatment resins are standard resins used in potable and high poryonifications and conform to FDA standards 21 CFR 173.25 and filters are validated for low media migration and with demonstrated microbial retentiveness. All of these materials 10 i meet and do not contribute contaminants to treated water systems. The PURE WATERare mere and is assembled using existing technologies, an RO unit with existing FDA marketing clearance and personnel with certification to Water Quality Association, Lisle, Illinois, standards of system design, maintenance and treatment.
Conclusion: PURE WATER Solutions, Inc. has designed a water treatment system for Hemodialysis. We believe this system is equivalent to an FDA approved system currently on the market, namely, the predicate device from Mar Cor Service, Inc. 510(k) #K945559. The the mailed, amazerials that are safe and effective and methods of design, construction and installation sanctioned by current standards in industry. We therefore request that PURE WATER Solutions' PURE WATER-CDS be granted substantial equivalence.
