It works as a second-stage filter downstream of a coarse pleated cartridge, polishing the water before it reaches a carbon block or UV stage. Unlike a pleated cartridge, polyspun is a depth filter — particles are trapped throughout the fibre matrix, not just on the surface. These cartridges are replace-only; they are not cleanable or reusable.\u003c\/p\u003e\n\n\u003cp\u003eAvailable in two brands, two sizes, and two micron ratings. Choose Davey for certified, premium performance. Choose Waimana for reliable everyday filtration at a sharper price.\u003c\/p\u003e\n\n\u003cp\u003eFits most 10\" Jumbo housings (10\" x 4.5\" cartridge) and 20\" Jumbo housings (20\" x 4.5\" cartridge) — including Davey, Pentair, Puretec, Trevoli, and most other major brands. Jumbo housings take a 4.5\" diameter cartridge. If you're unsure whether your housing is Jumbo or Standard, measure the cartridge diameter — Jumbo is 4.5\", Standard is 2.5\".\u003c\/p\u003e\n\n\u003ch2\u003eChoose Your Brand\u003c\/h2\u003e\n\n\u003ch3\u003eDavey Microlene — Premium\u003c\/h3\u003e\n\u003cp\u003eThe Davey Microlene polyspun cartridge is certified to AS\/NZS 4020 for use in contact with drinking water.

Required as a pre-filter for UV disinfection systems treating rainwater or tank water where cysts may be present.

Choose 5 micron if you're on mains water, cysts are not a concern, and you prefer a longer service interval between replacements. Lower micron ratings filter finer but clog faster, especially on dirty supplies.\u003c\/p\u003e\n\n\u003ch3\u003eWhich brand should I choose?\u003c\/h3\u003e\n\u003cp\u003eIf you want a certified cartridge — particularly for drinking water supplies — choose Davey. Both the 1 and 5 micron Davey Microlene polyspun cartridges are certified to AS\/NZS 4020, the NZ and Australian standard for products used in contact with drinking water. If you're filtering for general household use on a tighter budget, Waimana delivers reliable fine sediment removal at a better price point.\u003c\/p\u003e\n\n\u003ch3\u003eWhich size should I choose?\u003c\/h3\u003e\n\u003cp\u003eMatch the cartridge size to your housing. If your housing takes a 10\" x 4.5\" cartridge, choose 10\" Jumbo. If it takes a 20\" x 4.5\" cartridge, choose 20\" Jumbo. Not sure? Measure the cartridge you're replacing — Jumbo is 4.5\" in diameter. If you're still unsure, get in touch and we'll help you identify the right fit.\u003c\/p\u003e\n\n\u003ch3\u003eWill it fit my housing?\u003c\/h3\u003e\n\u003cp\u003eThis cartridge fits most 10\" and 20\" Jumbo housings — including Davey, Pentair, Puretec, Trevoli, and most other major brands. The key measurement is diameter: Jumbo housings take a 4.5\" diameter cartridge. If your housing takes a 2.5\" diameter cartridge, you need the Standard size, not this one.\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, not just on the surface. Once loaded, it cannot be effectively cleaned. Replace when flow drops noticeably, or at least every 6–12 months.\u003c\/p\u003e\n\n\u003ch3\u003eHow often do I need to replace it?\u003c\/h3\u003e\n\u003cp\u003eEvery 6–12 months is the general guideline, but it depends on your water quality and sediment load. The 1 micron rating will load up faster than the 5 micron on the same supply. On heavily contaminated tank water, you may need to replace more frequently. Replace when flow drops noticeably.\u003c\/p\u003e\n\n\u003ch3\u003eWhat does AS\/NZS 4020 mean?\u003c\/h3\u003e\n\u003cp\u003eAS\/NZS 4020 is the Australian and New Zealand standard for products used in contact with drinking water. A product certified to this standard has been independently tested and confirmed safe for use in drinking water systems. The Davey Microlene cartridges carry this certification. The Waimana cartridges do not.\u003c\/p\u003e\n\n\u003ch3\u003eDoes the 1 micron cartridge protect against bacteria?\u003c\/h3\u003e\n\u003cp\u003eNo. At 1 micron this cartridge removes fine particles and cysts such as Giardia and Cryptosporidium, but it 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.
