Every cartridge consists of thousands of thermally bonded fibres that won't shift with changes in flow or pressure. It carries WaterMark certification (WMTS-103, Lic. 22987) and is tested in compliance with AS\/NZS 4020 for use in contact with drinking water.\u003c\/p\u003e\n\n\u003cp\u003eSuits rainwater, bore, and mains water supplies. The 20\" jumbo format delivers high flow rates and extended filter runs, making it well suited to larger homes or systems with higher demand. Used in the second stage of filtration for finer sediment removal, or as a pre-filter ahead of UV treatment, carbon filtration, or reverse osmosis. The 1 micron variant carries a Cryptosporidium cyst removal rating of greater than 99%.\u003c\/p\u003e\n\n\u003cp\u003eNot cleanable. Replace every 12 months or when flow rate drops noticeably.

They use a depth filtration structure rather than a surface filtration structure. Polyspun is typically used for finer sediment removal in the second stage of filtration; pleated cartridges are more common as a coarser first stage. Polyspun also tends to have a higher dirt-holding capacity for fine particles.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I know when to replace it?\u003c\/h3\u003e\n\u003cp\u003eWhen flow rate drops noticeably, it's time to replace. Don't wait for flow to stop completely — a significant pressure drop means the cartridge is loaded and your system is working harder than it should be.\u003c\/p\u003e\n\n\u003ch3\u003eDo I need special tools to change the cartridge?\u003c\/h3\u003e\n\u003cp\u003eYou'll need a housing wrench to open the filter housing — most housings include one.
