  • A buyer here is paying for taste, not for a health claim, and should treat it that way.

  Express Water ROALK10

  • The remineralisation stage does what it claims and makes a measurable difference to mouthfeel, and independent testing of the sibling RO5DX recorded a final-stage pH of 9.0.

  Aquasure Premier Advanced 75 GPD

  Nothing recorded.

• Certification CoverageExpress Water ROALK10: 2Aquasure Premier Advanced 75 GPD: 2

  Express Water ROALK10

  • The system holds no NSF listing, so the alkaline claim and the contaminant list both rest on the manufacturer's own data.

  Aquasure Premier Advanced 75 GPD

  • The certification picture needs stating carefully: Aquasure's only NSF listing anywhere covers two RO membrane part numbers under NSF/ANSI 58 for material and structural integrity requirements only, which verifies that the membrane does not leach and holds pressure, not that it removes anything.
  • Nothing here is certified for contaminant reduction performance, so the 99 percent figure in Aquasure's copy is a manufacturer claim with no test report behind it.

  • Product. r/HydroHomies discusses this exact system and concludes the water does come out alkaline but that the strength drifts over cartridge life.
  • Wider r/WaterTreatment threads recommend the platform for taste and value while flagging the involved install and the cabinet space the tank demands, and O-rings weeping at the housings recur as the mechanical complaint across the range.

  • Product.
  • Two r/WaterTreatment and r/HomeMaintenance threads cover this exact system.
  • One owner reports installing the Premier and measuring 420 ppm TDS at the RO faucet, falling to about 360, which is a poor rejection figure and drew a run of diagnostic replies.
  • The second describes the Flowlok leak-detection disc deploying during a filter change when a drain-line restrictor fitting leaked, which reads as the safety feature working rather than a defect.
  • Beyond those, Aquasure discussion in the subreddit is about the softeners, and the general view of budget under-sink RO there is sceptical about wastewater and mineral removal rather than about this brand.

  • WaterFilterGuru bench-tested the platform's RO5DX with Tap Score lab analysis at 8.13 overall and measured a final stage lifting pH to 9.0, which is the closest independent measurement of this remineralisation stage available.
  • TapWaterData records that no alkaline SKU appears in any certifier's database, so the mineral claim rests on Express Water's own data.

  • An independent lab tester excluded the platform's RO5DX from a best-of list over its three-flush break-in, which applies to this chassis.
  • Hands-on videos of the alkaline configuration report clean taste and predictable upkeep, but the highest-reach ones carry affiliate codes or a sponsorship disclosure and are not weighted.

  • Product-line.
  • IrixGuy's Adventure Channel, 98,800 subscribers, has two independent owner reviews of the Premier RO - one after several months at 6,100 views and a several-years follow-up - and a separate third-party self-install walkthrough covers the same 4-stage system.
  • None names a specific capacity, so this is the Premier line rather than this model.
  • The under-sink RO roundups that bench-test at this price point still do not include Aquasure, so there is owner evidence but no independent testing.
  • Brand-level coverage is the Harmony softeners: DIY Homestead Projects at roughly 115,000 views, NKP Home Improvement at roughly 94,000, geminidrums at 15,000 on the fine mesh and IrixGuy's two-year owner review at 13,000.

  • The brushed nickel and extra-output variants carry their own ASINs with no ratings on them, so this figure belongs to the chrome system rather than to a shared file.

  • Home Depot reads 4.5 of 5 from 41 reviews on the brushed nickel version of this system, which is the identical hardware with a different faucet finish.
  • The pool is native, with verified-purchase entries and Aquasure replying under its own support address, and at 41 reviews it is comfortably above the ten-review floor and the deepest product-level retailer pool on any Aquasure RO.
  • The rest of the Premier range sits lower at the same retailer, 4.2 from 10 on the 100 GPD Pro and 4.0 from 8 on the alkaline version, so this is the best-reviewed of them rather than a figure that carries across the line.
