Price: wellssingapore.com's own product page (WooCommerce structured data, checked 2026-08-06) shows S$1,880.00 as the current price against a struck-through "original price" of S$2,280.00 (schema.org priceSpecification, validThrough 2027-12-31 — an extended-duration "sale", not a short-lived promo, so S$1,880 is recorded as the standing price; S$2,280 noted here as the list/reference price). Independently corroborated on tangs.com (an authorised SG retailer) at the same S$1,880.00, checked 2026-08-06 (https://tangs.com/product/true-tankless-cooling-water-purifier). IMPORTANT — GST: wellssingapore.com's own structured pricing data explicitly marks "valueAddedTaxIncluded": false for this price. It is not published elsewhere on the page whether the displayed cart/checkout price adds GST on top of S$1,880 — flagging since the schema convention elsewhere assumes GST-inclusive pricing; this may not be. Filtration not classified: product page describes a "Multi-Carbon Filter and Nano Clean Filter" removing heavy metals, excess chlorine and "up to 99.9% of noroviruses and bacteria" (9-step filtering overall) but never labels the technology as RO, UF, carbon, or ceramic — left null rather than inferred from the virus/bacteria-removal claim. No filters/consumables pricing published on wellssingapore.com or found via search — Wells appears to run a service-based model ("Filter replacement and sterilizing spray services available; contact +65 8797 8383") rather than selling standalone filter cartridges online; filters list left empty per the "unknown -> null/omit, never guess" rule rather than fabricating a price/interval. Warranty, installation fee, and servicing terms: not published anywhere found on wellssingapore.com (no dedicated warranty/terms page exists on the domain — checked /warranty/, /terms-conditions/, /terms-and-conditions/, all 404 as of 2026-08-06); the product page states only that the warranty "covers manufacturing defects" without a term length. Some third-party/secondary sources mention figures between 1 and 4 years but none were confirmed on Wells' own site, so left null rather than guessed. Power: 220V~, 60Hz; cooler 0.3A / heater 2300W; "1st grade energy efficiency rating" (source: product page). 7 temperature options (36.5/50/70/85°C hot; 10°C cold, 8°C super cool); dispense volumes 120/250/550ml or continuous. "99.9% [sterilisation] verified by Korea Testing & Research Institute" is a vague third-party-test-institute claim without a named standard/scope — recorded here in notes, not under `certifications`, per the SCHEMA.md rule that vague "tested by X" claims are not certifications.
