Price ambiguity, larger than usual: product page shows a struck-through reference price of SGD 889 against a currently-charged price of SGD 298 (66% off), no visible end-date. Recorded the charged price (298) per SCHEMA.md's perpetual-sale rule (record what a buyer actually pays today); the 889 strikethrough is an anchor figure kept here for the record. Unusually large gap (66%) — flagged for quarterly re-verification, since a reversion toward 889 would materially change this model's 5-year TCO ranking. Model produces alkaline (HydroPlus®, pH 9.0±0.5) or neutral-pH (HydroPure™, pH 7.5±0.5) ambient water only — no hot/cold output, direct-pipe connection, no electricity required. Filtration classified as `uf`: filter pack includes an "Advanced Ultra Hollow Membrane Filter" plus carbon and mineral/ionisation stages; classified by its membrane technology even though it also performs pH adjustment, which the schema's filtration enum has no separate category for — the ionisation/alkaline function is not reflected in `filtration`. Filter pack interval: page states "Recommended replacement 12 Months/3,600 Litres." Installation fee (SGD 120): same general "standard installation cost" figure used across novita's catalogue (see novita-w1i notes) — not itemised specifically for this model. All 4 colour variants (Vista White, Ivory Beige, Pastel Mint, Baby Pink) showed as sold out at time of verification (2026-08-06); treated as a stock-level detail, not discontinuation, since the product page carries no "no longer available" designation. Certifications: none formally scoped/published on novita's site; left empty per schema.
