It carries WaterMark certification (WMTS-103, Lic. 22987) and is tested in compliance with AS\/NZS 4020 for use in contact with drinking water. Davey holds ISO 9001 (quality management) and ISO 14001 (environmental management) certification.\u003c\/p\u003e\n\n\u003cp\u003eSuits rainwater, bore, and mains water supplies. The 20\" jumbo format delivers very high flow rates and extended filter runs, making it well suited to larger homes, commercial applications, or systems with high sediment loads. Works as a first-stage sediment filter, or as a pre-filter ahead of UV treatment, carbon filtration, or reverse osmosis.\u003c\/p\u003e\n\n\u003cp\u003eUnlike disposable depth cartridges, the pleated design can be cleaned and reused multiple times before replacement is needed. When flow slows, remove the cartridge, rinse it under a tap or gently hose it off, sterilise, and reinstall. 1 and 5 micron cartridges typically clean once or twice; 20 and 50 micron can be cleaned several times.\u003c\/p\u003e\n\n\u003cp\u003eAvailable in 1, 5, 20, and 50 micron so you can match the cartridge to your water quality and system needs.
