Data notes

Same underlying platform/filtration as Sterra X Tabletop (sterra-x-tabletop): 4-stage filtration — sediment filter -> pre-carbon filter -> "Nano Filter UF Membrane (~0.001 microns)" -> post-carbon filter — classified as `uf` on the strength of the explicit "UF Membrane" wording on the Sterra X product pages. This is the floor-standing configuration (1115mm tall, freestanding unit) vs. the 520mm tabletop unit; tank capacity: cold 3.8L, hot 2L (larger hot tank than the tabletop variant's 1.5L). Colour: Black. Filter option: Neutral pH or Alkaline. Filter pricing tiers (source: filter product page, checked 2026-08-06) — same filter product serves both Sterra X variants: Neutral pH — 6-month (1 set) S$189, 1-year (2 sets) S$368, 2-year (4 sets) S$736. Alkaline — 6-month S$239, 1-year S$468, 2-year S$936. Filter entry above uses the single-set/6-month neutral-pH list price. Power: AC 220-240V or 100-127V, 50/60Hz; consumption cold 110W / hot 450W (source: product page). Certifications: "Safety Mark Number 211275-11" is Singapore's electrical/consumer product Safety Mark, not a water-filtration certification with published scope — not recorded under `certifications`.
