Made entirely from food-grade polypropylene with no gaskets, binders, fillers, loose fibres, or surfactants. Thermally bonded fibres are less likely to shift with changes in flow or pressure, and do not release contaminants downstream. Exceptionally clean — meets regulatory guidelines for drinking water, food, and pharmaceutical use.\u003c\/p\u003e\n\n\u003cp\u003eThe longer 20\" length holds more filter media than the 10\" equivalent — higher flow rates and longer service life between replacements. The right choice for larger households, higher-usage installations, or supplies with heavier sediment loads.\u003c\/p\u003e\n\n\u003cp\u003eUnlike pleated cartridges, polyspun is a depth filter — particles are trapped throughout the fibre matrix. It is not cleanable or reusable. Replace when flow drops noticeably, or at least every 12 months.\u003c\/p\u003e\n\n\u003cp\u003eFits most 20\" Standard housings — including Pentair, Puretec, Trevoli, and most other major brands.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e⚠ Standard housings take a 2.5\" diameter cartridge.

Choose 5 micron for finer sediment removal or as a second-stage filter. Choose 1 micron where cyst protection is required — Giardia and Cryptosporidium — or as the final filtration stage before UV disinfection. Lower micron ratings filter finer but clog faster, especially on dirty supplies.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's the difference between the 10\" and 20\" versions?\u003c\/h3\u003e\n\u003cp\u003eBoth use the same polyspun melt media and carry the same certifications. The 20\" version is longer — it holds more filter media, which gives it a higher flow rate and longer service life between replacements. Choose the 20\" for larger households, higher usage, or properties where the 10\" needs replacing too frequently.\u003c\/p\u003e\n\n\u003ch3\u003eWill it fit my housing?\u003c\/h3\u003e\n\u003cp\u003eBefore ordering, measure the diameter of the cartridge you're replacing. Standard = 2.5\". Jumbo = 4.5\". These are not interchangeable — a Standard cartridge will not seat correctly in a Jumbo housing. This cartridge fits most 20\" Standard (2.5\") housings including Pentair, Puretec, Trevoli, and most other major brands. If you're unsure, get in touch before ordering.\u003c\/p\u003e\n\n\u003ch3\u003eCan I clean and reuse this cartridge?\u003c\/h3\u003e\n\u003cp\u003eNo. Polyspun is a depth filter — particles are trapped throughout the fibre matrix and cannot be effectively cleaned. Replace when flow drops noticeably, or at least every 12 months.\u003c\/p\u003e\n\n\u003ch3\u003eHow is this different from the pleated version?\u003c\/h3\u003e\n\u003cp\u003eThe pleated cartridge has a folded polyester membrane that filters on the surface — it can be cleaned and reused. The polyspun cartridge traps particles throughout the fibre matrix — it cannot be cleaned and is replace-only. Polyspun is made entirely from food-grade polypropylene with no binders or fillers, making it exceptionally clean for drinking water applications. It also handles higher temperatures — up to 63°C vs 52°C for the pleated version.\u003c\/p\u003e\n\n\u003ch3\u003eWhat do the certifications mean?\u003c\/h3\u003e\n\u003cp\u003eWaterMark WMTS-103 (Lic. 22987) means the cartridge has been independently tested and certified against Australian and New Zealand water industry standards. AS\/NZS 4020 means it has been tested and confirmed safe for use in contact with drinking water.\u003c\/p\u003e\n\n\u003ch3\u003eDoes the 1 micron cartridge protect against bacteria?\u003c\/h3\u003e\n\u003cp\u003eNo. The 1 micron cartridge has a Cryptosporidium cyst removal rating of more than 99%, but does not remove or inactivate bacteria or viruses. UV disinfection is required for bacteria and virus protection.\u003c\/p\u003e\n\n\u003ch3\u003eWhat warranty applies?\u003c\/h3\u003e\n\u003cp\u003eFilter cartridges are consumable items.
