Cartridges do most of the heavy lifting in any water filter, and once they are full of the stuff you are trying to block out, the system stops performing. Chlorine, rust, and fine grit slowly build up until the water flow drops or the taste starts to change. Swapping in a fresh cartridge at the right time is a small job that makes a big difference, keeping your water clear and stopping the filter from working harder than it should.
Here you will find a wide mix of replacement cartridges sized to suit the filter systems commonly found in New Zealand kitchens and homes. Some are made for everyday taste and odour improvement with carbon blocks, others are built to catch sediment, and a few are designed for tougher jobs like pulling out fluoride or heavy metals. Whether you are on town supply in Auckland or running tank water at the bach, the right cartridge from Water Filters Online will keep your system running steady.
