10 Best Water Purifier Suppliers in Singapore (2026)

Many Singapore households and offices choose a dedicated water purifier or dispenser over the kettle and bottled-water delivery, mainly for instant hot and cold water, extra filtration on top of tap water, and everyday convenience. The market here runs from long-established Korean rental brands to homegrown Singapore companies that design and assemble their own units, sold outright or offered on a rental plan. The ten suppliers below all currently operate in Singapore and publish details of their filtration type and service model on their own sites. Compare them on filtration, hot/cold features and rental versus purchase. Treat this as a shortlist to research further, not a fixed ranking.

Cuckoo markets itself as South Korea's top-selling home appliance brand and runs one of the largest water purifier ranges in Singapore, from compact tabletop units to full standing models such as the Titan and King Top. The company says several of its purifiers use a multi-stage filtration system it calls Nano Positive Filtration, and it built its local business around a rental model: customers pay a recurring plan rather than buying outright, with Cuckoo's own technicians handling filter changes and maintenance every few months under what it calls CUCKOO+ Care Service. An outright purchase option exists too. Its nationwide store and service-centre network suits buyers who prefer not to manage filter changes themselves.

Coway is a Korean home-appliance company that, by its own account, serves more than six million customers worldwide, with water purifiers sitting alongside its air purifiers and bidet seats. Its Singapore site references Water Quality Association (WQA) certification for parts of its range but does not spell out exact filtration stages or temperature settings model by model, so ask for a specific unit's filter breakdown and features before buying. It is unclear from the Singapore site alone whether a given model is sold outright, rented, or both, worth confirming directly since Coway runs both structures in some other markets. The company keeps a Woodlands showroom, best visited by appointment, and offers servicing through its own technicians.

Wells describes itself as a Korean lifestyle appliance brand established in 2002, with its water purifiers and dispensers designed and made in Korea. The range runs from compact countertop units like the Wells Mini up to design-forward standing models such as Wells The One and Wells Ice One, which the company markets as much on looks as on function. Wells does not spell out specific filtration stages on its main site, so it is worth asking about a particular model's cartridge or membrane type before you buy. The brand runs a showroom at Tradehub 21 in Boon Lay where units can be viewed in person, plus a separate line for installation and after-sales service.

Novita is a Singapore company, headquartered off Tagore Drive with a retail store at Plaza Singapura, that positions its water purifiers alongside air purifiers and dehumidifiers under one wellness-appliance range. Its water line includes reverse-osmosis countertop and standing dispensers, water ionisers, and hot-and-cold units with built-in ice makers, some carrying a five-year warranty by the company's own account. Novita sells outright through its e-store but also runs a Workplace Leasing Program aimed at offices that would rather lease than buy, plus a group-buy scheme for bulk orders. The company points to past Reader's Digest Trusted Brand recognition in the water purifier category, though that reflects a consumer survey rather than independent lab testing.

Sterra is a homegrown Singapore brand, now operating under Stryv, that sells its own line of tank and tankless water purifiers direct to consumers. The tankless Sterra 7 and Sterra 8 dispense hot and cold filtered water without a storage tank, while the Sterra X and Sterra Y are tank-based tabletop or standing alternatives. The company says it is trusted by more than 10,000 Singaporeans, though it does not publish exact filtration-stage specifications on its main product pages, so ask about a specific model's filter cartridge before ordering. Sterra sells outright with free delivery and installation rather than a rental plan, and it runs walk-in stores across the island, including at Ubi, Tampines Mall and Jurong Point.

Hydroflux says it was founded in 2012 as a Singapore homegrown brand and designs its own range of water dispensers rather than reselling other manufacturers' units. Its line-up spans bottled and bottleless countertop and standing dispensers, with models such as the NAMI adding auto-sterilisation and the WISH marketed as Singapore's first tankless dispenser with a stainless-steel flow path; most units offer hot and cold water, with some, like the PILSU, offering several preset temperatures. Hydroflux sells on a purchase basis through its own e-store and runs a trade-in programme for customers replacing an older purifier. The company keeps a showroom at T-Space in Tampines and operates separate sales and servicing hotlines for filter changes and repairs.

Livingcare describes itself as a local homegrown firm with more than 15 years in the water purification and dispenser business. Its range includes the slim, tankless Jewel and Pearl series dispensers, the under-sink LUMIERE with a multi-function hot, cold and ambient-water faucet, and the ONYX standing purifier, which the company says uses dual thermoelectric cooling modules in an ultra-slim chassis. Livingcare sells the units outright rather than on a rental plan and runs a trade-in programme for households upgrading from an older dispenser. It operates a showroom at Link@AMK in Ang Mo Kio, and says it provides year-round servicing support, though it is worth confirming current call-out times and coverage directly.

Happie is a Singapore water-purifier company that says it was founded by Benjamin, drawing on his background in the water purification industry, and describes the brand as inspired by premium Korean-made purifiers. Its range covers countertop and under-sink purifiers plus shower filters, with the company stating that its systems combine RO, UV and UF filtration stages to remove chemicals, pesticides and dissolved impurities. Products are sold outright, with professional installation offered for under-sink and shower-filter models. Happie runs an experiential showroom at 1 Sims Lane, near Aljunied MRT, where units can be seen running before you buy, and provides a direct enquiry line for service requests once a purifier is installed.

Coral Pure Natural says it began research and development in 2011 and commercialised its systems in 2016, positioning itself as a Singapore company that develops and assembles its own dispensers rather than reselling other manufacturers' machines. Its Premium series runs from the compact Premium 4 up to the slimmer Premium 9, with the company describing a multi-stage reverse-osmosis process, quoting filtration as fine as 0.0001 microns, and marketing its water as alkaline and mineral-enriched with temperature settings from ambient up to a near-boiling option. The company cites SGS and TUV lab test results for water quality, which buyers can ask to see directly. Units are sold outright, and Coral Pure Natural runs a showroom on Defu Lane in Hougang.

UltraPure positions itself as a one-stop shop for water filtration in Singapore, covering household drinking-water systems as well as commercial, industrial and seawater filtration equipment, a broader remit than the more consumer-facing dispenser brands on this list. Its home range spans countertop, under-sink and whole-house systems built on reverse osmosis, ultrafiltration, mixed-bed deionisation or activated carbon. UltraPure is also the authorised distributor and stockist for Watts water-quality products from the United States, alongside its own systems. It sells on a purchase basis from its Joo Chiat Road premises rather than a rental plan, and does not publish company history or founding details on its site, making it more a specialist supplier than a lifestyle brand.
