Trevoli UVLED Underbench UV Water Filter - 2 or 4 Stage, Mains and Rainwater NZ

Trevoli UVLED — Underbench UV Water Filter and Steriliser

Safe, clean drinking water at your kitchen tap — chemical-free, no benchtop drilling required.

The Trevoli UVLED series are underbench LED UV steriliser and filtration systems designed to provide clean drinking water for residential properties. Both models are suitable for mains and rainwater supplies. A dedicated drinking water faucet is included.

This is a point-of-use system. It treats drinking water at your kitchen tap — without paying to filter water that goes to the toilet, garden, or shower. If you want filtered water at every tap throughout the home, a whole-house system is the right choice.

The UV uses a Smart Flow Switch ballast. The UV LED activates only when water is flowing through the system — and switches off automatically when flow stops. This preserves LED life and reduces power consumption compared to systems that run continuously. There is no countdown timer on these models.

A pressure reducing valve is required for installation. This system should always be installed with a pressure reducing valve — this is a mandatory installation requirement, not an optional add-on. Your plumber will need to supply and fit one.

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.

UVLED81 — 2 Stage (Sediment + UV)

• Stage 1: 1 micron polyspun filter — removes suspended particles including sand, silt, dirt, and rust
• Stage 2: LED UV steriliser — neutralises 99.99% of harmful micro-organisms

Best for homes that want reliable bacteria and sediment protection without taste and odour treatment.
Dimensions: 133mm L x 385mm H x 160mm W

UVLED82 — 4 Stage (Sediment + Carbon + UF + UV)

• Stage 1: 1 micron polyspun filter — removes suspended particles including sand, silt, dirt, and rust
• Stage 2: 5 micron carbon block filter — reduces chlorine, odours, tastes, smells, colours, sand, salt, and rust particles
• Stage 3: Ultrafiltration (UF) 0.1–0.01 micron — effectively reduces colloids, proteins, bacteria, viruses, parasites, protozoa, pyrogens, and other organic molecules larger than 0.01 micron
• Stage 4: LED UV steriliser — neutralises 99.99% of harmful micro-organisms

Best for homes that want bacteria protection plus taste, odour, and ultrafiltration treatment.
Dimensions: 300mm L x 385mm H x 160mm W

Frequently Asked Questions

Which model is right for my home?

Both models neutralise 99.99% of harmful micro-organisms and include a sediment filter. The UVLED81 is the straightforward option — sediment filtration and UV sterilisation. The UVLED82 adds a carbon block stage for taste and odour treatment, plus ultrafiltration down to 0.01 micron for additional reduction of bacteria, viruses, parasites, and organic compounds. If you want the most comprehensive point-of-use treatment, the UVLED82 is the better fit. If you just need reliable bacteria and sediment protection, the UVLED81 is solid. Not sure? Get in touch.

How does the Smart Flow Switch work?

The UV LED activates automatically when water flows through the system and switches off when flow stops. This preserves LED life and uses less power than systems that run continuously. There is no countdown timer — the UV runs only when it's needed.

Is this the right system for my home?

If you want UV-treated, filtered drinking water at your kitchen tap — without a whole-house system — the UVLED is a strong fit. It treats water at one tap only. If you want filtered water at every tap in your home, get in touch and we'll recommend the right whole-house system for your supply.

Does it need to be installed by a plumber?

For anyone confident with this style of plumbing, the install is straightforward — the system arrives with all the components listed above and connects under the sink. The faucet will require a hole in the benchtop or sink. A pressure reducing valve is required and must be installed as part of the setup. If you'd prefer to have it done, a plumber can fit it quickly. If you're not sure, get in touch.

What is a pressure reducing valve and why do I need one?

A pressure reducing valve (PRV) regulates the water pressure entering the system. The UVLED series must always be installed with one — it protects the system and ensures correct operation. Your plumber can supply and fit the right PRV for your installation.

Can I use it with rainwater?

Yes. Both models are suitable for mains and rainwater supplies. 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.

Does the UVLED82 remove viruses?

The brochure states that the UVLED82's ultrafiltration stage effectively reduces colloids, proteins, bacteria, viruses, parasites, protozoa, pyrogens, and other organic molecules larger than 0.01 micron. The UV steriliser also neutralises 99.99% of harmful micro-organisms.

How often do I replace the filters?

Replacement intervals are not stated on the brochure. Get in touch and we'll advise based on your water source and usage.

What warranty does it come with?

2 years.
