- Residential Water Filtration
Cleaner, softer, healthier water for every Kiwi home
From under-sink reverse osmosis at the kitchen tap to whole-house systems
that protect every appliance, we engineer residential water filtration around
New Zealand’s unique water conditions.
Why residential water filtration matters in New Zealand
New Zealand has some of the cleanest tap water in the world on paper, but most council supplies are still treated with chlorine or chloramine to keep the network safe. That treatment leaves a chemical taste and smell, dries out skin and hair, damages fish and plants, and can shorten the life of expensive appliances like dishwashers, washing machines, hot water cylinders and espresso machines. In rural areas, tank water and bore water bring a different set of problems — sediment, iron staining, manganese, hardness and the very real risk of bacteria such as E. coli. A properly designed residential water filtration system removes those contaminants at the point of entry, the point of use, or both. That means crystal-clear drinking water, scale-free showers and kettles, healthier skin, longer-lasting plumbing, and complete peace of mind for your family. It is one of the few home upgrades that pays for itself in lower bottled-water spend, fewer appliance repairs and fewer service
calls.
Reverse osmosis (RO) drinking water systems
Reverse osmosis is the gold standard for residential drinking water in New Zealand. A multi-stage RO system installed under your kitchen sink pushes water through a semi-permeable membrane, removing up to 99% of dissolved solids, heavy metals, fluoride, chlorine, pesticide residues and microplastics. The result is bottled-water quality straight from a dedicated tap.
Our most popular residential system is the Direct Flow RO 800GPD — a tankless, 4-stage RO that delivers up to 800 gallons of fresh water per day on demand, with no bulky storage tank cluttering the cupboard. It is ideal for busy New Zealand families, working-from-home professionals and anyone who hates the chlorine taste of council water. Membranes typically last 2–3 years; pre-filters are changed every 6–12 months.
Whole-house water filtration systems
If you want every tap, shower and appliance in your home to enjoy filtered water — not just the kitchen — a whole-house filtration system is the answer. We size the system to your home’s flow rate (usually 60– 100 L/min for a typical Kiwi household) and stack the right combination of stages: sediment filtration to capture rust and grit, KDF/carbon to remove chlorine, chloramine and chemicals, scale control to protect appliances, and UV sterilisation for tank or bore water.
Whole-house systems are particularly valuable in Christchurch (hard aquifer water), Hamilton and the Waikato (high mineral content), Hawke’s Bay (bore water), and rural Northland and Coromandel (tank and rainwater). They also dramatically reduce the chlorine-related skin irritation and asthma triggers that affect a surprising number of New Zealand households.
Tank, rainwater & bore water solutions
More than 400,000 New Zealand homes rely on tank water, rainwater or private bore water — and the regulations are far less strict than for council supply. We design custom multi-stage systems with sediment pre-filtration, carbon block, scale control, and UV disinfection (with optional ultrafiltration) to deliver safe drinking water that meets Drinking-water Standards for New Zealand. Common rural problems we solve include: brown or yellow water from iron, eggy smell from hydrogen sulphide, hard scale build-up on showerheads, sediment clogging cartridges within weeks, and unsafe bacterial loads from contaminated bore heads or roof catchments. We test, design and install — and we offer scheduled servicing so you never have to think about it again.

Frequently Asked Questions
What is the best water filtration system for New Zealand homes?
The best system depends on your water source and household needs. Most NZ homes benefit from a whole-house filtration system for chlorine and sediment removal, often combined with reverse osmosis (RO) for drinking water. We recommend systems based on your local water quality and usage.
Do I need a water filter if I'm on council water in NZ?
Council water is treated and safe, but it often contains chlorine and impurities that affect taste and smell. A filtration system improves water quality, taste, and appliance lifespan, which is why many homeowners still choose to install one.
How much does it cost to install a water filter in New Zealand?
Costs vary depending on the system. Under-sink filters typically start from $300–$800, while whole-house systems range from $1,500–$5,000+ installed. We provide tailored quotes based on your setup and water quality.
How often should water filter cartridges be replaced?
Most filters need replacing every 6–12 months, depending on usage and water conditions. Regular replacement keeps your system running efficiently and maintains water quality.
Do you service rural properties on tank or bore water?
Yes, we specialise in tank and bore water systems. These usually require multi-stage filtration, such as sediment filters and UV sterilisation, to ensure safe and reliable water year-round.
Do you offer trade pricing for plumbers and resellers?
Yes, we offer trade pricing and support for plumbers, builders, and resellers. This includes bulk discounts, technical guidance, and fast delivery across New Zealand.
