NSF-61 Restriction Statement: “Copper Tube (Alloy C12200) is certified by NSF to NSF/ANSI Standard 61 for public water supplies meeting or in the process of meeting the U.S. EPA Lead and Copper Rule (56FR 26460, June 7, 1991). Water supplies with pH less than 6.5 may require corrosion control to limit copper solubility in drinking water.”

Demand Factory or Government Recall & XRF Inspection

If you already own a GFX check its coil for NSF/ANSI Incise Marks. If none are found demand a Factory Recall and file complaints to U.S. Consumer Product Safety Commission (Re: Complaint #H0990104A) and/or Health Canada because copper tubing for drinking water exported into Canada must be third-party certified & GFX-knockoffs exported into the U.S. must bear NSF-61 incise marks.
