Chromium-6 in Patterson water

What RO does for chromium-6
RO can reduce chromium-6. According to the California State Water Board, “RO is a mature and viable technology for hexavalent chromium removal.” [California State Water Board, Hexavalent Chromium MCL Initial Statement of Reasons] That’s the state’s statement about the technology; we don’t claim our unit is certified for chromium-6. We test before and after, and you see the results.
Real Patterson installs
The photos on this page are from a Patterson kitchen: an under-sink system with its own storage tank. Our AquaShield 5500, built on the PureGen Pro Q+, is a 4-filter, 5-stage design built with NSF-certified components. In Patterson we usually pair it with a softener, because 400-ppm (parts per million) water is hard on an RO membrane.
Sodium and minerals, too
Patterson’s water averages 107 ppm sodium before any softener. [City of Patterson 2025 Consumer Confidence Report] RO reduces sodium and dissolved minerals in drinking water, which is why coffee, tea and ice taste noticeably cleaner.
