Waimana Waiora Essence Plus I Whole House Mains Filter - Single Stage, 20 Inch Jumbo, Chlorine Removal NZ

City mains water is treated before it reaches your home — but the chlorine used in that process can leave your water tasting and smelling flat. The Waiora Essence Plus I filters it out. This is a single-stage whole house system built for larger New Zealand homes on town water. A 5 micron carbon block removes chlorine taste and odour from every tap in the house — drinking water, cooking, coffee, ice. The 20 inch jumbo housing delivers higher flow capacity and longer cartridge life than the 10 inch equivalent, making it the right choice for larger homes and higher-demand supplies. The housing arrives pre-mounted on a powder-coated bracket, ready to go on the wall. Connection is standard 25mm BSP. Filter changes are DIY-friendly with the included housing spanner.

Most customers notice the difference in their drinking water, tea, and coffee straight away. The 20 inch format provides more carbon contact time and greater dirt-holding capacity, extending cartridge life compared to a 10 inch system under the same conditions. If you're also dealing with sediment, rust flakes, or grit from older supply lines, the Waiora Essence Plus II adds a sediment pre-filter upstream of the carbon block and protects the carbon stage from loading up prematurely.

It's designed for larger New Zealand homes on town (mains) water where chlorine taste and odour is the main concern. If you have a smaller home or lighter usage, the Waiora Essence I with a 10 inch housing covers the same job in a more compact format. For rainwater or bore water, get in touch and we'll point you in the right direction. What's the difference between the Essence Plus I and Essence Plus II? The Essence Plus II adds a polyspun sediment filter as a first stage, upstream of the carbon block. If your mains supply has visible sediment, rust flakes, or grit, the two-stage system protects the carbon block and extends its service life. If your water is clean and your only concern is taste and odour, the Essence Plus I is sufficient. What's the difference between the Essence I and Essence Plus I? Both are single-stage carbon block systems. The Essence Plus I uses a 20 inch jumbo housing — higher flow capacity and longer cartridge life between changes. It's the better choice for larger households with higher water demand. 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 Essence Plus I arrives fully assembled, uses standard 25mm BSP fittings, and mounts with the included hardware. If you're confident with household plumbing, the installation is straightforward. If you're not sure, get in touch and we'll help you decide. How often do I replace the cartridge? Every 6–12 months, depending on your water quality and usage. A return of chlorine taste or odour is the clearest signal it's time to replace — even if flow rate is still good. The 20 inch format typically extends cartridge life compared to a 10 inch system under the same conditions. 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 affect my water pressure? The 20 inch jumbo housing is specifically designed for higher-flow applications. Keep the cartridge replaced on schedule — a clogged cartridge is the most common cause of pressure drop. What warranty does it come with? 3 years.
