Data notes

Price: wellssingapore.com's own product page (WooCommerce structured data, checked 2026-08-06) shows S$2,080.00 current against a struck-through "original price" of S$2,480.00 (schema.org priceSpecification, validThrough 2027-12-31). Independently corroborated on tangs.com (authorised SG retailer, "Slim One Water Purifier") at the same S$2,080.00, checked 2026-08-06 — though that TANGS listing shows the item as sold out, so treat with slightly more caution than the brand-site figure. IMPORTANT — GST: same structured-data flag as other Wells models — "valueAddedTaxIncluded": false is set on this price; unclear whether checkout adds GST on top of the displayed S$2,080. Type/tankless: wellssingapore.com's own product page for this model describes it only as a "direct-dispenser water purification system" and never uses the word "tankless"; classified as tankless here on the strength of Wells' regional sites (e.g. wells.co.th "Wells Slim One Tankless Water Purifier") and the fact the design has no reservoir tank, but flagging that the SG page itself doesn't use the term. Filtration not classified: page describes "Wells Carbon and Neo Nano Clean filters" that remove heavy metals, chlorine, and "99.9% of bacteria and noroviruses" but never names the technology as RO/UF/carbon/ceramic — left null rather than inferred. No filters/consumables pricing published on wellssingapore.com or found via search — see wells brand notes; filters list left empty rather than guessed. Warranty/installation fee/servicing: not published on wellssingapore.com (no dedicated warranty page found on the domain, checked 2026-08-06) — left null. Power: 220-240V~, 50/60Hz; cooler 0.5A / heater 2500W (source: product page). 8 temperature options (Cold/Mild Cold/27/40/50/60/70/85°C); dispense volumes 120/250/550ml/1L/2L. Colours: Marble White, Marble Warm Grey, Rose Gold. Ultra-slim 160mm width is the headline marketing feature.
