Trusted water filtration specialists in Wellington
Wellington — the capital — is a key service area for The Filter Guy, with installs across the city centre, Te Aro, Thorndon, Karori, Kelburn, Newtown, Miramar, Lower Hutt, Upper Hutt, Porirua and the Kāpiti Coast. Government departments, hotels, embassies, hospitality groups and thousands of Wellington homes rely on us for clean, reliable water filtration.
Understanding Wellington's water
Wellington Water supplies the metropolitan region from a network of dams, river takes and aquifers, treated to NZ Drinking-Water Standards with chlorine and (in some zones) fluoride. Residents commonly seek us out to remove the chlorine taste, fluoride for sensitive families, and to soften variable hardness. Older Wellington homes also experience pipework sediment that benefits from sediment pre-filtration, and the broader Kāpiti and Hutt regions include rural properties on tank and bore water needing full multi-stage treatment.
