      APEC ROES‑PHUV75

      • Its strongest attribute is that the UV stage sits after the membrane and the remineralisation cartridge, which is the correct order and means the lamp treats already-polished water.
      • That gap matters more than an unverified taste claim, because a UV system with no rated dose offers no evidence at all against the organisms it is sold to handle.

      Express Water ROALKUV10

      • Stacking UV and remineralisation costs ninety-two dollars over the plain RO10 and adds no footprint, which is the genuinely clever part of the design.
      • Neither added stage carries certification - no NSF/ANSI 55 for the UV and no published dose, no verification of mineral output for the alkaline cartridge - so the buyer is trusting Express Water on both.
    • Certification CoverageAPEC ROES-PHUV75: 2Express Water ROALKUV10: 2

      APEC ROES‑PHUV75

      • Its weakest is the absence of NSF/ANSI 55, the only performance standard that exists for ultraviolet disinfection, which means the dose this lamp delivers has never been verified by anyone outside APEC.
