Trusted water filtration specialists in New Plymouth
New Plymouth and the Taranaki region — from the city itself out to Bell Block, Waitara, Inglewood and Stratford — are an important market for The Filter Guy, with strong demand from the energy sector, dairy industry and a growing residential population.
Understanding New Plymouth's water
New Plymouth’s mains water is generally good quality but treated with chlorine, and residents typically install carbon-based filtration to remove chemical taste. The Taranaki ring-plain is heavily rural with extensive dairy farming — many properties use bore or stream water that requires significant pre-treatment before drinking.
Our water filtration services in New Plymouth
Our New Plymouth team delivers the full range of water filtration services — under-sink reverse osmosis (RO) for pure drinking water at the kitchen tap, whole-house filtration to protect every appliance and shower, commercial RO for cafés, restaurants, offices and clinics, and large-scale industrial and ultra-pure water plants for research, food processing and manufacturing. We also handle ongoing servicing, genuine cartridge replacement, RO membrane changes, UV lamp swaps, water testing and emergency call-outs. Through our group company Membrane Solutions NZ we can quote spiral-wound RO, ultrafiltration and nanofiltration membranes for larger New Plymouth commercial and municipal projects, and through Wholesale Filters NZ we supply the country’s largest catalogue of replacement cartridges with same-day NZ-wide dispatch.
