Data notes

4-stage filtration named on product page: 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. Tank capacity: cold 3.8L, hot 1.5L. Colours: Black, White. Filter option: Neutral pH or Alkaline (alkaline-variant filter set priced differently — see below). Filter pricing tiers (source: filter product page, checked 2026-08-06): Neutral pH — 6-month (1 set) S$189, 1-year (2 sets) S$368, 2-year (4 sets) S$736, 3-year set discontinued. Alkaline — 6-month (1 set) S$239, 1-year (2 sets) S$468, 2-year (4 sets) S$936. The filter entry above uses the single-set/6-month neutral-pH list price; bulk sets carry a small implicit discount per 6-month unit (e.g. 2-set/1-year works out to S$184/6mo) but are not used here since that requires dividing a bundle price, which the filter block records as-published per SKU. This product page and the "Sterra X Tank Standing" page (sterra-x-standing) both surface overlapping tabletop/standing spec info in places; tabletop-specific figures (520mm height, 20kg, 1.5L hot tank) were used for this file, standing-specific figures for the sterra-x-standing file. 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`.
