Data notes
coway.sg's own product pages are client-rendered and did not expose pricing to automated fetching (see brand notes). Purchase price $3,088.00 sourced instead from the BigGo Singapore price-comparison aggregator (https://biggo.sg/s/coway+water, verified 2026-08-06), which attributes the listing to "Coway Singapore Official Store" on Shopee at the product_url above; the Shopee page itself returned no readable content to automated fetching (likely bot-blocked), so the price could not be independently re-verified on the retailer page directly — flagged as a source-quality caveat. GST-inclusiveness of this price is not stated. Also marketed with an ice-maker (crystal "bullet ice") as its differentiating feature. Dimensions/weight/warranty/filter prices were found repeatedly on Coway MALAYSIA's site (coway.com.my — e.g. 270 x 546 x 515mm, 23.9kg, 6-stage RO + dual UV, 1+1 year filter & warranty) but are NOT recorded here because that is not an SG-official or SG-retailer source per this project's sourcing rules; treat those MY-market figures as unverified for the SG unit. Filtration marketed as "6-stage RO filtration combined with dual UV sterilisation" per third-party (MY-market) sources, not confirmed on an SG source — filtration recorded as "other" rather than "ro" pending SG-side confirmation.
