Waimana Waiora II Whole House Water Filter - 2 Stage, Rainwater, Mains or Housing Only NZ

Waimana Waiora II — Whole House Water Filter System

Clean water at every tap — choose the configuration that suits your supply.

The Waimana Waiora II is a 2-stage whole house filtration system using twin 10" Jumbo housings, pre-mounted on a powder-coated steel bracket and ready to go on the wall. Available in three configurations — a rainwater setup, a mains water setup, or housings only if you want to supply your own cartridges.

Connection fittings are not included. The system uses standard 25mm BSP connections — your plumber can supply the appropriate fittings from any plumbing merchant.

Bore water quality varies significantly. We recommend testing your bore water before selecting a filtration system — get in touch and we'll help you choose the right configuration for your supply.

Choose Your Configuration

Waiora Clarity II — Rainwater / Tank Water

For New Zealand homes, baches, and properties on rainwater or tank water. Filters out the dust, silt, leaf matter, and fine sediment that collects in tanks and comes off roofs.

Stage 1 — 20 Micron Pleated Sediment Filter

Catches coarser particles first — dirt, debris, leaves, and organic matter from your tank. Starting coarse extends the life of Stage 2.

Stage 2 — 1 Micron Polyspun Sediment Filter

Captures fine silt and particles that passed Stage 1. Together, both stages produce clear water ready for drinking, cooking, or UV treatment downstream.

Note: The Clarity II removes sediment and particulates. It does not treat bacteria or micro-organisms. If you want to treat your rainwater for drinking, a UV system installed downstream is the recommended next step. Get in touch and we'll help you put together the right setup.

Waiora Essence II — Mains / Town Water

For New Zealand homes on town (mains) water. Filters out sediment and removes the chlorine taste and odour that can make tap water flat and uninviting.

Stage 1 — 1 Micron Polyspun Sediment Filter

Traps rust flakes, fine particles, and grit from the mains supply. Protects Stage 2 and your appliances from build-up over time.

Stage 2 — 5 Micron Carbon Block Filter

Reduces chlorine, chemical tastes, and odours. Most households notice the difference in their drinking water, tea, and coffee straight away.

Waiora II — Housing Only

The twin housings with bracket and hardware, no cartridges included. For those who want to supply their own cartridges, replace existing housings, or build a custom setup. Fits standard 10" x 4.5" Jumbo cartridges.

Frequently Asked Questions

Which configuration should I choose?

If you're on rainwater or tank water and want to remove sediment and silt — choose the Clarity II. If you're on town (mains) water and want to remove chlorine taste, odour, and sediment — choose the Essence II. If you want the housings only to build your own setup or replace existing housings, choose Housing Only. Not sure? Get in touch and we'll help.

Does the Clarity II make rainwater safe to drink?

The Clarity II removes sediment and particulates — it does not treat bacteria or other micro-organisms. For drinking water from rainwater or tank supplies, a UV disinfection system downstream is the recommended next step. Get in touch and we'll help you put together the right setup.

Does it need to be installed before or after my pump?

After the pump — on the outlet side. The Waiora II protects your appliances and fittings downstream. If you need pre-pump protection, get in touch and we can advise on the right setup.

Do I need a plumber to install it?

For most customers, yes — a licensed plumber is the safest path and protects your warranty on the plumbing side. The Waiora II arrives fully assembled, uses standard 25mm BSP fittings (not included), and mounts with the included hardware. If you're confident with household plumbing, the installation itself is straightforward. If you're not sure, get in touch and we'll help you decide.

What connection fittings will I need?

The system uses 25mm BSP connections. Fittings are not included — your plumber can supply the appropriate fittings from any plumbing merchant.

How often do I replace the cartridges?

Every 6–12 months depending on your water quality and usage. For the Clarity II, check the pleated cartridge first — if it's visibly loaded with debris, it's time. Higher sediment loads will shorten cartridge life. Replace sooner if you notice a drop in flow rate.

Do I need bypass valves?

They're not included, but they're worth adding. Bypass valves let you isolate the filter during cartridge changes without shutting off water to the rest of the house. Ask us about adding a set when you order.

Will it fit a small space?

The 10" Jumbo size is compact compared to 20" systems — well suited to pump sheds, small utility spaces, and tight cupboards.

Is it suitable for bore water?

Bore water quality varies significantly. We recommend testing before installing. Get in touch and we'll help you choose the right configuration for your supply.

What warranty does it come with?

3 years.
