  Aquasure Premier Advanced Alkaline 75 GPD

  • Aquasure's claimed 8.5 to 10 pH range is at the aggressive end of what remineralisation cartridges achieve, and the upper figure would be unusual in practice;

  • Five separate stages is a real architectural difference rather than a badge, and at nearly twice the weight of the standard chassis the build is visibly heavier.
  • Express Water publishes no pH range, no mineral output figures and holds no certification for this model, which for a product sold on mineral content is the central weakness.
• Certification CoverageAquasure Premier Advanced Alkaline 75 GPD: 2Express Water ROELITE9: 2

  • no test data supports either end.
  • The RO hardware underneath is identical to the standard model, including the 1.5 to 1 drain ratio that is the best specification on either system.
  • Certification is unchanged and worth restating: Aquasure's only NSF listing covers two RO membrane part numbers for material and structural integrity, not for removing anything, and the lead-free faucet claim is a component materials certification.

  • Product-line.
  • Two r/WaterTreatment and r/HomeMaintenance threads cover the Premier RO platform this system is built on.
  • One owner reports 420 ppm TDS at the faucet on a new install, settling to about 360, which is a poor rejection figure; the second describes the Flowlok leak-detection disc deploying during a filter change when a drain-line fitting leaked, which reads as the safety feature working.
  • Nothing addresses the alkaline stage specifically, and the subreddit's general scepticism about alkaline water claims is background rather than evidence about this unit.

  • Product-line. r/HydroHomies concludes Express Water's alkaline filtration does produce alkaline water but that strength drifts over cartridge life, which bears directly on a model sold on five mineral stages.
  • Wider r/WaterTreatment threads recommend the platform for taste and value while calling the install involved.
  • No thread names the Elite specifically.

  • WaterFilterGuru bench-tested the platform's RO5DX with Tap Score lab analysis at 8.13 overall and measured a remineralisation stage lifting pH to 9.0.
  • TapWaterData's certification audit records no certifier listing for the Elite, so its mineral claims rest entirely on Express Water's own data.

  • 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 alkaline stage is not addressed in any of them, and the RO roundups that bench-test at this price point do not include Aquasure.
  • 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.

  • No separate Amazon listing for the alkaline 75 GPD configuration carries a readable rating; the replacement alkaline cartridge has its own pool and is a consumable, not the system.
  • The score falls back to the Premier 75 GPD at 4.4 from roughly 276, which is the same system without the remineralisation stage.

  • The Elite appears in Amazon's own Express Water comparison table at 4.1 from 40 ratings - a real pool above the ten-review floor, and the lowest-rated reverse osmosis system Express Water sells there.
  • Every sibling in the same table reads 4.4 to 4.6, so the gap is the finding rather than noise.

  • Home Depot lists this alkaline model at 4.0 of 5 from eight reviews, which is below the ten-review floor and not scorable on its own, so the figure used is the standard Premier Advanced at 4.5 of 5 from 41 reviews on the same RO hardware.
  • That pool is native, with verified-purchase entries and Aquasure replying under its own support address.
  • Scored a point below the standard model because the alkaline version's own eight-review file, thin as it is, points lower rather than higher, and because the 100 GPD Pro at 4.2 from 10 sits between them.
