Waiora Clarity III Whole House Rainwater Filter - 3 Stage, 10 Inch Jumbo, Sediment & Taste Removal NZ

Rainwater picks up a lot on its way from the sky to your tap. Dust, organic matter, and fine silt settle in your tank over time — and without the right filtration, that shows up in the taste and smell of your water. The Waiora Clarity III deals with all of it.

This is a 3-stage whole house system designed for New Zealand homes and baches on rainwater or tank water. Stage one catches the coarser debris with a 20 micron pleated filter. Stage two follows with a 1 micron polyspun filter to trap fine silt and sediment. Stage three uses a carbon block to remove organic tastes and odours. Clear, fresh-tasting water from every tap.

The triple 10 inch jumbo housings arrive pre-mounted on a powder-coated bracket, ready to go on the wall. Compact enough for a small pump shed or tight utility space. Connection is standard 25mm BSP. Filter changes are DIY-friendly with the included housing spanner.

How it works

Stage 1 — Coarse Sediment

The 20 micron pleated filter catches the larger particles first — dirt, debris, leaves, and organic matter that collect in your tank. Starting coarse protects the stages downstream and extends overall cartridge life.

Stage 2 — Fine Sediment

The 1 micron polyspun filter captures the fine silt and particles that passed through Stage 1. By the time water reaches Stage 3, it's clear and ready for the final treatment.

Stage 3 — Carbon Block

The 5 micron carbon block removes organic tastes and odours — the earthy, musty qualities that sediment filters alone don't address. The result is water that tastes as clean as it looks.

Frequently asked questions

Is the Clarity III right for my home?

It's designed for New Zealand homes, baches, and properties on rainwater or tank water where sediment and taste are both a concern. If sediment alone is your issue, the Clarity II (2-stage) may be sufficient. If you're on town water, the Essence range would suit better — get in touch and we'll point you in the right direction.

How is the Clarity III different from the Clarity II?

The Clarity II is a 2-stage system focused on sediment removal. The Clarity III adds a carbon block as the final stage, which tackles the organic tastes and odours that sediment filters don't address. If your tank water smells earthy or tastes flat, the Clarity III is the better choice.

Does the Clarity III make rainwater safe to drink?

The Clarity III removes sediment, particulates, and organic tastes and odours. It does not treat bacteria or other micro-organisms. If you want to treat your rainwater for drinking, a UV system added downstream is the recommended next step. Get in touch and we can help you put together the right setup.

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

The Clarity III is installed on the outlet side of your pump — after the pump, before the rest of the house. This means it protects your appliances and fittings downstream, not the pump itself. 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. That said, the Clarity III arrives fully assembled, uses standard 25mm BSP fittings, 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.

How often do I replace the cartridges?

Every 6–12 months, depending on how much sediment and organic matter is in your water. Check the pleated filter first — if it's visibly loaded with debris, it's time for a change. Higher silt loads will shorten cartridge life.

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.

What warranty does it come with?

3 years.
