What is it indicated for?

The AmeriWater Purification System for Hemodialysis is used to remove organic and inorganic substances and microbial contaminants from water. Purified (or treated) water will then be used to prepare and dilute dialysate concentrate to form dialysate and/or rinse dialyzers for multiple-use dialyzers. AmeriWater does not recommend nor endorse any other use for water treated with AmeriWater systems. AmeriWater further does not endorse any specific hemodialysis or reprocessing procedures or equipment.

*Note: Federal Law restricts this device to sale by or on the order of a physician for use as a water treatment device for hemodialysis.

Indications for use as stated in the FDA summary.
