No chemicals or glue is used in construction.\u003c\/p\u003e\n\u003cp\u003eFine fibres handle efficient particle removal while coarser fibres give the cartridge structural strength. By varying fibre size and density through the cartridge, a true depth filtration gradient is created, capturing particles of different sizes as water passes through.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003e5 micron\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e— first stage.

Use this after a coarser pre-filter (or after the 5 micron) to catch finer particles that get through the first stage. Running 1 micron as a lone first-stage filter on heavily sedimented water (especially tank\/bore supply) will clog it fast and shorten its life significantly.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eSo for a typical two-cartridge setup: 5 micron polyspun → CTO carbon, or for a three-stage setup: 5 micron polyspun (1st) → 1 micron polyspun or pleated (2nd) → CTO (3rd).\u003c\/p\u003e","brand":"DLM Wallace","offers":[{"title":"1 Micron","offer_id":45800583626854,"sku":"20BPP01","price":44.99,"currency_code":"NZD","in_stock":true},{"title":"5 Micron","offer_id":45800583659622,"sku":"20BPP05","price":39.99,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0600\/4588\/5542\/files\/Whole-house-filtration---polyspun-filter-20-inch.png?v=1737422518","url":"https:\/\/dlmwallace.co.nz\/products\/20-jumbo-polyspun-filter-1-5-micron","provider":"DLM Wallace","version":"1.0","type":"link"}
