What Is Whole House Water Filtration?

A whole house filtration system is installed at the point of entry — where your water supply enters the property. That means every tap, shower, washing machine, and appliance in your home gets filtered water. Not just the kitchen sink.

Auckland's municipal water is treated and generally safe, but it still contains chlorine, sediment, and trace contaminants. A whole house system removes these before the water reaches any part of your home. The result is better tasting water, less scale build-up in your hot water cylinder, and cleaner water for showering and laundry.

Benefits of Whole House Filtration

How It Works

The system goes inline on your main water supply, usually near your toby (water meter) or where the supply enters the house. Water passes through one or more filter stages before it reaches your internal plumbing.

Single-stage systems

A single sediment or carbon filter. Good for basic chlorine and sediment removal. Low maintenance — just swap the filter cartridge every 6-12 months.

Twin or multi-stage systems

A sediment pre-filter followed by a carbon block filter. The sediment filter catches particles first, protecting the carbon filter and extending its life. This is the most common setup we install.

Specialty systems

For tank water or bore water properties, we can add UV sterilisation and additional filtration stages to handle bacteria, iron, and other contaminants specific to untreated water sources.

Brands We Install

We supply and install systems from trusted brands that are well-supported in New Zealand:

We'll recommend the right system based on your water source, household size, and what you want to filter out.

Maintenance Schedule

Whole house filters need regular cartridge replacement to keep working properly:

We offer a scheduled replacement service — we'll come out, swap the filters, and check the system is running right. No need to remember when it's due.

Frequently Asked Questions

Will a whole house filter reduce my water pressure?

A properly sized system won't noticeably affect your pressure. We size the filter housing and cartridges to match your pipe size and flow rate. If your pressure is already low, we'll address that as part of the install.

How much does a whole house filtration system cost?

It depends on the system type and installation complexity. A basic single-stage system is the most affordable option. Multi-stage or UV systems cost more. We'll give you a straight price including supply and installation.

Do I still need a separate drinking water filter?

A whole house system handles chlorine and sediment, which covers most people's concerns. If you want an extra level of filtration for drinking water specifically — like removing heavy metals or fluoride — an under-bench filter at the kitchen tap is a good add-on.

Can you install a system on tank water?

Absolutely. Tank water often needs more filtration than mains water — sediment, tannins, and bacteria can all be issues. We typically install a sediment pre-filter, carbon filter, and UV steriliser for tank water properties.

How long does installation take?

Most whole house filter installations take 2-3 hours. We'll need to shut off the water supply during install — usually about an hour. We'll let you know in advance so you can plan around it.
