Two entities are involved in the SG water-purifier business and philips.com.sg does not name a single SG entity for the water range, so `company` is left null rather than picking one: (1) philips.com.sg's own privacy notice names the operating group entity as "Versuni Netherlands B.V." (the former Philips Domestic Appliances business, sold by Philips to Hillhouse Investment in 2021 and rebranded Versuni in 2023, still trading under Philips brand license) — https://www.philips.com.sg/c-e/shop/ho/privacy-notice.html, checked 2026-08-06. (2) Locally, Philips Water customer care/support in Singapore is run by a separate local partner, IMS Marketing Pte Ltd, trading as "IMSSG" / "Philips Water Solution Singapore" (contact PhilipsWaterCare@imssg.com, 60 Marsiling Road SKM Building) — https://www.imssg.com/philips-water, checked 2026-08-06. service_model set to "outsourced" on the basis of (2): a distinct local partner (IMSSG), not Philips/Versuni directly, appears to run SG water-category service/support. origin left null: no brand-origin or manufacturing-origin statement was found on philips.com.sg for the water purifier range. Sourcing note affecting all Philips models in this dataset: philips.com.sg's product pages render prices client-side (not present in the page's static HTML/source, confirmed by direct fetch), so purchase and filter prices for Philips models here are sourced from major SG authorised retailers (Harvey Norman, Best Denki, Challenger) rather than philips.com.sg directly, per this project's rule for brand sites that lack a displayed figure. Philips SG's on-tap purifier range also churns SKUs quickly: several models (WP3811/00, WP3861/00, WP3887/01, WP4141/90) are marked "no longer available" directly on philips.com.sg as of 2026-08-06 despite still being listed for sale by third-party marketplaces — those were excluded as not currently sold per the brand's own site.
