sediment is captured toward the outside of the cartridge, while progressively smaller particles are captured deeper within the media.\u003c\/p\u003e\n\u003cp\u003eThis prevents larger particles from

\u003cstrong\u003eprogressively finer filtration throughout its depth\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eThe outside begins at approximately \u003cstrong\u003e25 micron\u003c\/strong\u003e, capturing larger particles, before the filtration becomes progressively finer toward the \u003cstrong\u003e1 micron inner filtration layer\u003c\/strong\u003e.\u003c\/p\u003e\n\u003ch3\u003eIs this a 1 micron filter?\u003c\/h3\u003e\n\u003cp\u003eIt provides \u003cstrong\u003e1 micron final filtration\u003c\/strong\u003e, but unlike a conventional 1 micron cartridge, it doesn't use the same fine filtration throughout its entire depth.\u003c\/p\u003e\n\u003cp\u003eThe outer media acts as a coarser prefilter before water reaches the fine inner media.\u003c\/p\u003e\n\u003ch3\u003eWhy is gradient density useful?\u003c\/h3\u003e\n\u003cp\u003eGradient density allows different particle sizes to be captured at different depths within the cartridge.\u003c\/p\u003e\n\u003cp\u003eLarger particles are trapped toward the outside while smaller particles penetrate further into the progressively finer media.\u003c\/p\u003e\n\u003cp\u003eThis makes better use of the available filter depth and increases sediment-holding capacity.\u003c\/p\u003e\n\u003ch3\u003eHow much sediment can it hold?\u003c\/h3\u003e\n\u003cp\u003eThe DGD design provides \u003cstrong\u003eup to three times the dirt-holding capacity of similar-size sediment cartridges\u003c\/strong\u003e, with even greater capacity than standard spun or string-wound cartridges.\u003c\/p\u003e\n\u003ch3\u003eWhat is the cartridge made from?\u003c\/h3\u003e\n\u003cp\u003eIt is manufactured from \u003cstrong\u003e100% pure polypropylene\u003c\/strong\u003e.\u003c\/p\u003e\n\u003ch3\u003eWill the filter affect the taste of my water?\u003c\/h3\u003e\n\u003cp\u003eThe polypropylene media is designed so it \u003cstrong\u003ewill not impart taste, odour or colour\u003c\/strong\u003e to the water being filtered.\u003c\/p\u003e\n\u003ch3\u003eIs it suitable for bore water?\u003c\/h3\u003e\n\u003cp\u003eYes. Its high sediment capacity and progressive filtration make it particularly useful where the incoming supply contains a mixture of larger and finer suspended particles.\u003c\/p\u003e\n\u003ch3\u003eIs it suitable for tank water?\u003c\/h3\u003e\n\u003cp\u003eYes. It can be used for sediment filtration on rainwater and tank-water systems.\u003c\/p\u003e\n\u003ch3\u003eCan I use it before a UV system?\u003c\/h3\u003e\n\u003cp\u003eYes. Its \u003cstrong\u003e1 micron final filtration\u003c\/strong\u003e makes it useful as a fine sediment stage before downstream treatment equipment such as UV.\u003c\/p\u003e\n\u003cp\u003eThe complete filtration and treatment requirements still depend on the quality of the incoming water.\u003c\/p\u003e\n\u003ch3\u003eIs this cartridge washable?\u003c\/h3\u003e\n\u003cp\u003eNo. This is a \u003cstrong\u003epolypropylene depth filtration cartridge\u003c\/strong\u003e, not a washable pleated cartridge.\u003c\/p\u003e\n\u003cp\u003eOnce sediment loading causes unacceptable restriction or the cartridge reaches the end of its useful service life, replace it.\u003c\/p\u003e\n\u003ch3\u003eWill it fit a standard 10\" water filter housing?\u003c\/h3\u003e\n\u003cp\u003eThis is a \u003cstrong\u003e10\" × 4½\" Jumbo \/ Big Blue cartridge\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eIt requires a compatible \u003cstrong\u003e10\" Jumbo \/ Big Blue housing\u003c\/strong\u003e and will not fit a slim 10\" Standard housing.\u003c\/p\u003e\n\u003ch3\u003eWhat's the product code?\u003c\/h3\u003e\n\u003cp\u003eThe product code is \u003cstrong\u003e10BDGD-PA\u003c\/strong\u003e.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":46054038601772,"sku":"10BDGD-PA","price":51.75,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0623\/5966\/6732\/files\/10BDGD-PAN-2000x2000.jpg?v=1787864015","url":"https:\/\/www.filtrationstation.co.nz\/products\/pentair-10-inch-jumbo-25-1-micron-gradient-sediment-filter","provider":"Filtration Station NZ","version":"1.0","type":"link"}
