Waiora Clarity Plus I + Waimana UV 48W Bundle - High Flow Filtration & UV Treatment NZ

Complete whole house filtration and UV treatment for tank and bore water — in a high-capacity 20 inch jumbo format. The Waiora Clarity Plus I handles coarse sediment removal in a larger 20 inch housing for higher flow rates and longer cartridge life, and the Waimana UV 48W unit treats water against bacteria, viruses, and microbes as it flows through at up to 45 L/min. The UV unit's flow-activated design means the lamp only runs when water is moving — no power wasted, no water warming in the chamber between uses. Suited to medium to large New Zealand homes on tank or rainwater supply with higher flow demand. Note: bore water quality varies significantly — we recommend testing your bore water before purchasing to ensure this configuration suits your supply. Get in touch and we'll help. Ships as two separate items: the Clarity Plus I filter system and the UV 48W unit arrive independently. What's in the bundle Waiora Clarity Plus I — 20 Inch Single-Stage Whole House Filter Stage 1: 20 micron pleated sediment filter (20" jumbo) — removes coarse sediment, silt, and particles. Greater capacity and longer cartridge life than a 10 inch cartridge. 20" jumbo housing with stainless threaded 25mm BSP ports High-flow 20 inch housing for larger homes and increased water demand Powder-coated steel bracket Housing spanner included 3-year warranty Waimana UV 48W — Flow-Activated UV Unit 48W UV chamber with integrated flow switch UV dose: 30 mJ/cm² at 45 L/min Treats water against bacteria, viruses, and microbes without chemicals Flow-activated — lamp runs only when water is flowing Connection: 25mm BSP Includes: UV lamp, quartz sleeve, ballast, flow switch, spring, O-rings 3-year warranty How the system works together Stage 1 — Coarse Sediment (Clarity Plus I) The 20 micron pleated filter removes larger particles, silt, and organic matter. The 20 inch format holds more sediment than a 10 inch cartridge, reducing the frequency of changes. Clear water at this stage is essential for effective UV treatment downstream. Stage 2 — UV Treatment (UV 48W) Water flows through the UV chamber where the 48W lamp treats it against bacteria, viruses, and microbes at a dose of 30 mJ/cm² at up to 45 L/min. The flow switch activates the lamp automatically when water moves and shuts it off when flow stops. The sequence matters — sediment filtration before UV ensures clear water enters the chamber, which is what makes UV treatment effective. If your water has a higher fine sediment or silt load, the Waiora Clarity Plus II + UV 48W bundle adds a 1 micron polyspun second stage between the pleated filter and the UV unit for more thorough particle removal before treatment. Get in touch if you're unsure which bundle suits your supply. Why Clarity Plus I over Clarity I The Clarity Plus I uses a 20 inch jumbo housing instead of a 10 inch. More filter media means greater sediment holding capacity, longer cartridge life, and better performance at higher flow rates. The matched 48W UV unit handles a higher flow rate of 45 L/min — better suited to medium to large homes with higher simultaneous water demand. A note on bore water Bore water quality varies significantly from site to site. We recommend having your bore water tested before selecting a filtration system — the mineral content, bacterial load, and other characteristics of your bore will determine whether this configuration is appropriate or whether additional stages are needed.

Replace when the filter is visibly loaded with debris or when flow rate drops noticeably. UV lamp: replace based on usage. UV output degrades before the lamp visibly fails — replace on schedule and clean the quartz sleeve at each lamp change.

Filtration removes sediment and particles. UV treats water against bacteria, viruses, and microbes. They address different things — filtration alone does not treat microbiological contamination, and UV alone cannot work effectively if the water is turbid or contains sediment. Together they provide comprehensive whole house treatment for tank and bore water. Why choose the Clarity Plus I over the Clarity I bundle? The Clarity Plus I uses a 20 inch jumbo housing for greater filter capacity and longer cartridge life. The matched 48W UV unit handles a higher flow rate of 45 L/min — better suited to medium to large homes with higher simultaneous water demand. If you have a smaller household, the Clarity I + UV 33W bundle may be the better fit. What's the difference between this bundle and the Clarity Plus II + UV 48W bundle? The Clarity Plus II bundle adds a 1 micron polyspun second stage between the pleated filter and the UV unit. This removes fine silt and particles that pass through the 20 micron pleated stage and provides additional particulate protection before UV treatment. If your water has a higher fine sediment load, the Clarity Plus II bundle is the better choice. Why does the order matter? UV treatment requires clear water. If sediment reaches the UV chamber, it blocks UV light from reaching micro-organisms — reducing or eliminating treatment effectiveness. The Clarity Plus I's sediment stage ensures clear water arrives at the UV chamber. Is this suitable for bore water? It can be, but bore water varies significantly from site to site. We recommend testing your bore water before ordering — get in touch and we'll help you confirm this is the right configuration for your supply. Do the two items need to be installed at the same time? They can be installed together or separately. The Clarity Plus I filter system is installed upstream and the UV unit downstream — the UV unit should always be the last stage before water enters the home. Do I need a plumber to install it? We recommend a licensed plumber for both components. The Clarity Plus I uses standard 25mm BSP fittings and arrives pre-assembled with a housing spanner. The UV unit uses 25mm BSP and plugs into a standard 240V outlet. What warranty applies? Both items carry a 3-year manufacturer's warranty. Filter cartridges and the UV lamp are consumables and are not covered.
