Purchase price not published on the product page — per Hydroflux's FAQ (https://www.hydroflux.com.sg/pages/faq), "Water purifiers are only available for purchase through our salesperson," consistent with no price being shown anywhere for this model (product page, collections listing, or search-indexed snippets). One informal Carousell (secondhand marketplace) listing mentioned "S$1,500 for a used unit purchased in Jan 2023" — NOT recorded as a fact since it is a resale price for a used unit, not a standard published new-unit price. Included in this dataset despite no price because it is marketed by Hydroflux as a bestseller and flagship model. Outputs: page states "5 instant hot & cold temperatures: 85°C, 75°C, 45°C, 27°C, 4°C" — recorded as [hot, cold, ambient] (27°C read as the ambient/room-temperature setting). Tankless per page ("Hot/Cold Tank Capacity: N/A"). Free delivery and installation stated ("Free delivery and installation"). Filter pack: "up to 4 years worth of filters" is advertised as included with initial purchase (contents/timing of that inclusion not detailed) — the $368.42 filter price recorded above is for a SEPARATE, standalone 1-year replacement pack (source: dedicated filter product page), containing "2 Premium Dirt & Organic Chemical Removal Filters" + "1 Nano Pro 2 Fine Particles, Bacteria, Virus Removal Filter"; GST-inclusive per that page. Installation type (countertop) inferred from Hydroflux's own "designed for households" tabletop-dispenser product category and the product's "slim and compact design" framing for kitchen counters — not stated in those exact words on the page. water_source (direct-pipe vs manual-refill) not stated anywhere found on hydroflux.com.sg, left null rather than assumed despite the unit clearly requiring installation. Filtration not branded RO/UF by Hydroflux on this page — left as "other". Warranty duration not stated on this page (contrast: Hydroflux's H2300/Undersink/H1675S/ H2200 model pages each separately state a 1-year warranty — suggestive but not confirmed for NAMI specifically, so left null). Company holds general BizSAFE3/ISO9001/SGS accreditations per other Hydroflux pages, but these are business/quality-management certifications, not a published water-filtration performance-testing scope — not recorded under `certifications`.
