Whole House Water Filters
Clean, great-tasting water at every tap.
Whole house water filtration for NZ homes
A whole house water filter is fitted where the water comes into your home, so every tap, shower, toilet and appliance gets filtered water, not just the kitchen tap.
We supply, install and service whole house filtration systems for homes across Rodney and North Auckland. On town water, it takes out the chlorine taste and smell at every tap, including the shower. On tank and bore water, we pair it with a UV water filter so every tap is protected from bacteria.
Every system is matched to your water supply and your home, and looked after with a yearly service.

What’s in your water?
Town water and tank or bore water have different problems. Find yours below, and find out more about each one.
On town water
Council supply. These are the most common reasons people choose a whole house filter.
Chlorine taste and smell
Carbon takes the chlorine taste and smell out of town water at every tap, including the shower and bath.
Lead and heavy metals
Older pipes and brass fittings can add lead or copper. KDF and carbon stages reduce heavy metals in the water.
Silica water spotting
Silica leaves white spots on glass, taps, showers and cars. Common in local water, and worth treating at the source.
On tank or bore water
Rainwater and groundwater. Bore water is always tested first.
Bacteria such as E. coli
Tank and bore water can carry bacteria. Filters alone don’t stop them, so we add a UV filter to protect every tap.
Roof run-off in tank water
Grit, leaves and metals such as copper wash off roofs and spouting. Find out which roofs cause the most problems.
Iron, manganese and hard water
Orange staining and scale come from bore water. These need a water softener rather than a filter.
Is a whole house filter right for you?
A whole house filter treats all the water you use, from the kitchen tap to the shower and laundry. It’s a good choice when:
- you can taste or smell chlorine in your town water, at the tap or in the shower
- you want filtered water at every tap, not just the kitchen
- you’re on tank or bore water and need filters and UV to protect every tap from bacteria
- older pipes and fittings may be adding lead or copper to your water
It isn’t the answer to everything. Hard water and iron or manganese staining are treated with a water softener. For fluoride, PFAS or nitrate in your drinking water, reverse osmosis at the kitchen tap removes far more.
We take care of everything
From the first visit to the yearly service, one local team looks after it all:
A free site visit
Water testing for bore water
A system matched to your water and flow
Installation by our registered plumbers
UV added for tank and bore water
Yearly service and cartridge changes
Reminders when your service is due
How it works
Four steps from your first call to clean water at every tap.
1
Site visit
We look at your water supply and plumbing. The site visit is free. Bore water is always tested first.
2
The right system
We learn about your water source, then size a system to suit your water and your home. You get a clear quote before we start.
3
Installation
Our registered plumbers fit it where the water comes into your home, then check the flow before we leave.
4
Yearly service
Every system needs a service every 12 months. We remind you, change the cartridges and replace the UV lamp if you have one.
Town water: whole house filter
Tank water: filters and UV
Bore water: water softener

Whole house filters for town, tank and bore water
Every supply is different. Here’s what we usually fit on each one.
Town water
Council supply
Carbon takes out the chlorine taste and smell at every tap. Our whole house ioniser has four stages: a sediment filter, carbon, KDF media to reduce heavy metals, and an ioniser. Don’t need the ioniser? Our Whole House Filter System is the same system without it.
Tank water
Rainwater
Sediment filters, then a UV filter to protect every tap from bacteria. Our Aqua BIG (1 to 2 bathrooms) and Aqua JUMBO (3 to 5 bathrooms) do both in one unit. We can add stages if your roof or spouting adds metals such as copper. Unfiltered tank water also leaves sediment in your hot water cylinder: see what 12 years of it did to one cylinder.
Bore and surface water
Groundwater, springs and streams
We always test first. If the water has iron, manganese or hardness, we add a water softener, and a UV filter protects every tap from bacteria.

Whole house water filter FAQs
What is a whole house water filter?
A whole house (point-of-entry) filter is fitted where the water comes into your home, so every tap, shower, toilet and appliance gets filtered water. An under-bench filter only treats the kitchen tap. Some homes have both.
What does a whole house water filter remove?
Sediment and dirt, the chlorine taste and smell, and, with KDF or carbon media, heavy metals such as lead and copper. Filters don’t kill bacteria, so on tank and bore water we add a UV filter. What a system removes depends on its cartridges, so we match them to your water.
Do I need a whole house filter on town water?
You don’t have to. Town water is treated to meet the drinking water standards. Many people choose one to take the chlorine out of every tap, the shower and the bath, and older pipes and fittings can add metals such as lead or copper. Find out more about chlorine in water.
Can a whole house filter help with eczema or sensitive skin?
After taste, skin is the most common reason our customers give. A whole house filter takes the chlorine out of your shower and bath water, and many customers tell us it makes a real difference. If you have a skin condition, talk to your doctor too.
Do I need a UV filter as well as a whole house filter on tank or bore water?
Yes. Sediment and carbon filters don’t stop bacteria such as E. coli or parasites such as Giardia. A UV water filter after the cartridges protects every tap in the house.
Will a whole house filter reduce my water pressure?
A correctly sized system shouldn’t noticeably reduce your pressure. We size the filter housings for your home’s flow and check your pump. Pressure can drop as the cartridges fill up with dirt, which is a sign they’re due for a change.
How often does a whole house filter need servicing?
Every 12 months, whether you’re on town, tank or bore water. We remind you when it’s due, change the cartridges and, if you have UV, replace the lamp.
Will a whole house filter fix hard water or iron staining?
No. Hardness, iron and manganese are mostly a bore water problem, and they’re treated with a water softener. We test your water first so the system matches it. Find out more about hard water.
Does a whole house filter remove fluoride or PFAS?
A standard whole house filter doesn’t remove fluoride or nitrate. For those, and for PFAS, we fit reverse osmosis at the kitchen tap. Many homes have both.
Do you service other brands of whole house filter?
Yes. As well as the systems we install, we service most makes and models, including Puretec, Davey Microlene, Alpine Pure, HRV, Kiwi Pure, Tru Water, Taylor Purification, Pure Flo Pro, Purely Water and Hygiene Direct.
How much does a whole house water filter cost?
You’ll find current prices in our online shop: the Whole House Ioniser System and Whole House Filter System for town water, and the Aqua BIG and Aqua JUMBO filter and UV systems for tank water. Installation depends on your plumbing and where the system goes, so after a free site visit we give you a clear quote.
Where does Aqua Works install whole house water filters?
Across Rodney and North Auckland, from Mangawhai to Albany, including Warkworth, Matakana, the Hibiscus Coast and Dairy Flat.
