Choose 5 micron for a second-stage fine sediment filter, or for cleaner mains supplies. 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 polyester pleated media and carry the same certifications. The 20\" version is longer — it holds more filter media, which gives it a higher flow rate, higher dirt-holding capacity, and longer intervals between cleaning and replacement. Choose the 20\" for larger households, higher usage, or properties where the 10\" needs servicing 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 really clean and reuse this cartridge?\u003c\/h3\u003e\n\u003cp\u003eYes. Rinse off accumulated sediment when flow drops, sterilise, and reinstall. Most cartridges can be cleaned multiple times before replacement is needed. The exception is 1 and 5 micron — these finer ratings may only clean once or twice. Replace when cleaning no longer restores adequate flow.\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 this cartridge protect against bacteria?\u003c\/h3\u003e\n\u003cp\u003eNo. The 1 micron rating removes cysts such as Giardia and Cryptosporidium, but does not remove or inactivate bacteria or viruses. UV disinfection is required for bacteria and virus protection.\u003c\/p\u003e\n\n\u003ch3\u003eHow does a pleated cartridge differ from a polyspun cartridge?\u003c\/h3\u003e\n\u003cp\u003eA pleated cartridge has a folded polyester membrane with a large surface area — it filters on the surface, can be cleaned, and handles high flow rates. A polyspun cartridge is a wound fibre depth filter — particles are trapped throughout the matrix and it cannot be effectively cleaned. Pleated suits applications where cleanability and flow rate matter; polyspun suits finer filtration where single-use disposable performance is preferred.\u003c\/p\u003e\n\n\u003ch3\u003eWhat warranty applies?\u003c\/h3\u003e\n\u003cp\u003eFilter cartridges are consumable items.
