Water passes through the full depth of the cartridge from outside to inside, with progressively finer filtration toward the centre. This depth-loading design means the cartridge holds more sediment before it restricts flow, compared to a surface-only filter.\u003c\/p\u003e\n\u003cp\u003eUnlike pleated cartridges, polyspun cartridges are not designed to be cleaned and reused. When flow drops noticeably, replace the cartridge.\u003c\/p\u003e\n\n\u003ch2\u003eChoosing the right micron\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003e1 micron\u003c\/strong\u003e — the finest option.

If you're unsure, get in touch and we'll help you choose.\u003c\/p\u003e\n\n\u003ch3\u003eHow is the 20 inch version different from the 10 inch?\u003c\/h3\u003e\n\u003cp\u003eThe 20 inch jumbo format contains more filter media — this means a higher flow rate (90 L\/min vs 50 L\/min), greater particle-holding capacity, and longer service life between replacements. It's the better choice for larger households and high-flow installations.\u003c\/p\u003e\n\n\u003ch3\u003eHow often do I need to replace it?\u003c\/h3\u003e\n\u003cp\u003eWe recommend replacing every 6–12 months depending on your water quality and usage. In high-sediment water you may need to replace more frequently. The clearest sign is a drop in water pressure or flow rate.\u003c\/p\u003e\n\n\u003ch3\u003eCan I clean and reuse this cartridge?\u003c\/h3\u003e\n\u003cp\u003eNo. Polyspun cartridges are not designed to be cleaned and reused. The fibres trap particles throughout the depth of the cartridge, and rinsing won't effectively restore flow. Replace when pressure drops.\u003c\/p\u003e\n\n\u003ch3\u003eWill it fit my housing?\u003c\/h3\u003e\n\u003cp\u003eIt fits most 20 inch jumbo housings — these take a cartridge that's 20 inches long and 4.5 inches in diameter. If you're not sure of your housing size, measure the inside diameter before ordering. Get in touch if you're not sure.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I know when to replace it?\u003c\/h3\u003e\n\u003cp\u003eThe clearest sign is a drop in water pressure or flow rate. When you notice the pressure is lower than usual, it's time to replace the cartridge.\u003c\/p\u003e\n\n\u003ch3\u003eDo I need special tools to change the cartridge?\u003c\/h3\u003e\n\u003cp\u003eJust the housing wrench that came with your system. Shut off the water first, unscrew the housing, swap the cartridge, and reinstall. A quick rinse of the housing while it's open is good practice.\u003c\/p\u003e\n\n\u003ch3\u003eIs it suitable for drinking water?\u003c\/h3\u003e\n\u003cp\u003eIt's made from food-grade polypropylene and is suitable for use in drinking water systems. The spec sheet cautions that it should not be used with microbiologically unsafe water without adequate disinfection — so if your water source carries biological risk, pair it with a UV system downstream.\u003c\/p\u003e\n\n\u003ch3\u003eWhat warranty applies?\u003c\/h3\u003e\n\u003cp\u003eFilter cartridges are consumables and don't carry a standard product warranty. If you receive a cartridge that is visibly damaged or defective, get in touch and we'll sort it out.\u003c\/p\u003e","brand":"Waimana Water","offers":[{"title":"1 micron: 20PP01","offer_id":45492374274092,"sku":"20PP01","price":45.0,"currency_code":"NZD","in_stock":true},{"title":"5 micron: 20PP05","offer_id":45492374306860,"sku":"20PP05","price":45.0,"currency_code":"NZD","in_stock":true},{"title":"10 micron: 20PP10","offer_id":45492374339628,"sku":"20PP10","price":45.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0623\/5966\/6732\/files\/2_Waimana20_PolyspunFilter_1b207952-7f7b-432e-84d8-15854c513ae7.jpg?v=1777328639","url":"https:\/\/www.filtrationstation.co.nz\/products\/waimana-20-inch-jumbo-polyspun-sediment-filter","provider":"Filtration Station NZ","version":"1.0","type":"link"}
