Whole House Water Filters NZ

Whole house water filtration for New Zealand homes

A whole house water filter treats water at the point it enters your home, so every tap, shower, bath, washing machine and hot water cylinder runs on filtered water — not just the kitchen. It removes the chlorine and sediment that dry out skin and hair, protects appliances from grit and scale, and for rural properties on rainwater or bore supply, adds UV sterilisation to make the water safe.

Why filter the whole house, not just the kitchen?

  • Skin and hair — chlorine is absorbed through the skin and inhaled as vapour in a hot shower. Whole house filtration is the fix for eczema, dry skin and dull hair across the family
  • Appliances — sediment and scale shorten the life of hot water cylinders, dishwashers and washing machines
  • Tank and bore water — rainwater picks up bird and possum contamination from the roof; bore water can carry E. coli and nitrates. UV is the only practical way to disinfect at household scale without chemicals
  • Taste everywhere — cooking, tea, ice, the dog's bowl: all filtered

Replacement cartridges

Whole house filter FAQs

Do I need a plumber to install a whole house water filter?
Yes. The system is installed on the incoming water main, usually in the garage or at the toby. Most installs take one to two hours.

Will a whole house filter lower my water pressure?
A correctly sized system has minimal effect on pressure. We size each system to the household's flow rate — tell us how many bathrooms and we'll match it.

Which whole house filter do I need for tank water?
Rainwater and bore supplies need UV sterilisation for bacteria, which the Elite-Home provides. Town supply only needs chlorine and sediment removal (Eco Series or Pro-Home).

Does a whole house filter remove fluoride?
No — fluoride removal at whole-house flow rates isn't practical. Pair a whole house system with an RO Mineral+ at the kitchen sink for fluoride-free drinking water.

How often do whole house cartridges need changing?
Every 12 months on town supply; more often on tank water with heavy sediment. Replacement sets are around $145 and we email a reminder.
