Waimana Waiora Pure Mini II Underbench UV Water Filter - 2 Stage, Flow-Activated UV NZ

Special offer — this listing includes a free set of replacement cartridges (1 micron sediment + 5 micron carbon block). While stocks last.

Clean, treated drinking water at your kitchen tap — without paying to filter water that goes to the toilet, garden, or shower.

The Waimana Waiora Pure Mini II is a compact two-stage underbench water filter with 6W UV sterilisation, designed for point-of-use treatment at the kitchen tap. It reduces sediment, chlorine, and odour through staged filtration, then treats bacteria, viruses, and microbes using UV light — no chemicals, no additives.

The UV ballast is flow-activated with a 5-minute delay-off. The UV lamp only runs when water is flowing, which extends lamp life and avoids unnecessary power use. The 5-minute delay keeps the chamber sterilised after the tap is closed.

The Pure Mini II suits mains supply, rainwater tanks, and bore water supplies. 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.

Everything needed for installation is included — filters, UV lamp, ballast, tubing, and fittings.

How it works

Stage	What it does
Stage 1 — 1 micron sediment filter	Removes fine particles, rust, and sediment before the water reaches the carbon stage.
Stage 2 — 5 micron carbon block filter	Reduces chlorine, taste, and odour for noticeably better-tasting water.
Stage 3 — 6W UV sterilisation	Treats bacteria, viruses, and microbes using UV light. No chemicals or additives. Flow-activated ballast with 5-minute delay-off.

UV dosage performance

UV Dose	Flow Rate
40 mJ/cm²	3 L/min
30 mJ/cm²	5 L/min
16 mJ/cm²	9 L/min

For full UV treatment effectiveness, flow should be kept at or below 3 L/min. Flow rate can be managed at the tap.

Frequently asked questions

Is the Pure Mini II right for my home?

It suits anyone who wants treated drinking water at the kitchen tap without filtering the whole house. If you're on mains supply and mainly want better-tasting, UV-treated drinking water, the Pure Mini II does that job efficiently and compactly. If you want treated water at every tap — laundry, bathrooms, outdoor taps — a whole-house system is the better fit.

Does it need to be installed by a plumber?

The system connects via 6mm push-fit fittings to the cold-water supply under the sink, and arrives ready to connect. For anyone confident with this style of plumbing, the install is straightforward. If you'd prefer to have it done, a plumber can fit it quickly.

What does the UV lamp do?

The 6W UV lamp treats bacteria, viruses, and microbes in the water passing through the stainless steel UV chamber. UV light disrupts the DNA of microorganisms, rendering them unable to replicate — no chemicals are added to the water.

How does the flow-activated ballast work?

The ballast starts the UV lamp when water flow is detected and keeps it running for 5 minutes after the tap is closed. The lamp doesn't run continuously — it operates only when needed, extending lamp life and reducing power use. The 5-minute delay-off keeps the UV chamber sterilised between uses.

Can I use it with rainwater or tank water?

Yes. The Pure Mini II suits rainwater and tank supplies. Two-stage filtration handles sediment and taste/odour, and the UV stage treats microbial content.

Can I use it with bore water?

The Pure Mini II can be used on bore water supplies, but 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.

How often do I need to replace the cartridges and UV lamp?

Filter cartridges should be replaced every 6–12 months depending on water quality and usage. The UV lamp should be replaced when the ballast indicates — the ballast monitors lamp output and signals when replacement is due.

Will it fit under my sink?

The unit measures 320 x 140 x 380 mm. It is designed for compact underbench installation and fits under most standard kitchen sinks. If your under-sink space is particularly tight, measure the available depth and height before ordering.

Does it slow down my water flow?

At the rated treatment flow of 3 L/min the system delivers full UV treatment — that's plenty for filling a glass, kettle, or pot without noticeable waiting. The maximum flow rate is 9 L/min, though UV effectiveness reduces at higher flows.

What warranty applies?

The Waimana Waiora Pure Mini II carries a 3-year warranty.
