The Davey Microlene 20 micron pleated is certified to AS\/NZS 4020, which is 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 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 really clean and reuse this cartridge?\u003c\/h3\u003e\n\u003cp\u003eYes. The pleated design is cleanable — rinse or soak off the accumulated sediment when flow drops, sterilise, and reinstall. Most cartridges can be cleaned multiple times before replacement is needed. Replace at least annually regardless of condition.\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 heavily on your water quality and sediment load. Tank water with high leaf or dirt contamination will load up a cartridge faster than clean mains water. Clean when flow drops noticeably — replace when cleaning no longer restores adequate flow.\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 cartridge carries this certification. The Waimana cartridge does not.\u003c\/p\u003e\n\n\u003ch3\u003eDoes this cartridge protect against bacteria or cysts?\u003c\/h3\u003e\n\u003cp\u003eNo. At 20 microns this is a coarse sediment filter — it removes dirt, rust, sand, and leaf matter. For bacteria and virus protection, UV disinfection is required. For cyst protection (Giardia, Cryptosporidium), 1 micron filtration is required downstream of this stage.\u003c\/p\u003e\n\n\u003ch3\u003eWhat warranty applies?\u003c\/h3\u003e\n\u003cp\u003eFilter cartridges are consumable items.
