Company entity per privacy policy (https://www.hydroflux.com.sg/policies/privacy-policy, verified 2026-08-06): "HYDROFLUX MARKETING PTE LTD", registered address 1 Tampines North Drive 1, #08-02, T-Space, Singapore 528559. Origin/founding per About page (https://www.hydroflux.com.sg/pages/about): "Founded in 2012, Hydroflux is a Singaporean homegrown household product brand that specialises in distribution and retail of high technology water filtration systems." Service model not clearly stated — the About page only says "our team strives to deliver the best in terms of during and after sales service," which doesn't confirm whether install/service technicians are direct employees or contracted; left null rather than guessed. Hydroflux's FAQ (https://www.hydroflux.com.sg/pages/faq) states: "Water purifiers are only available for purchase through our salesperson. You can send us a purchase enquiry here, or call us at +65 8388 8696 for the purchase of water purifiers!" — consistent with the brand's flagship product pages (NAMI, WISH, PILSU, etc.) not publishing purchase prices. Only a handful of simpler/compact SKUs (e.g. LITE+ Compact) and filter replacement packs show prices directly on the site. No rental/subscription plan was found published anywhere on hydroflux.com.sg — Hydroflux appears to be purchase-only (price on application) rather than rental-based, unlike Coway/Cuckoo.
