Constructed from 100% pure polypropylene with a dual-gradient density profile, the cartridge increases effective filter depth and dirt-holding capacity without adding taste, odor, or color to your water. It meets NSF\/ANSI 42 material requirements and works with residential, rural, municipal, and light commercial systems.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the dual-gradient design improve filtration performance?\u003c\/h3\u003e\n\u003cp\u003eThe dual-gradient structure compresses fibers more tightly toward the cartridge core, creating deeper, staged capture zones. This design traps larger particles on the outer surface while finer particulates are caught deeper inside, which extends service life and reduces channeling.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDirt-holding capacity up to three times that of comparable single-density cartridges.\u003c\/li\u003e\n  \u003cli\u003e233% greater effective filter depth for staged particle capture.\u003c\/li\u003e\n  \u003cli\u003eLow pressure drop: under 1 psi at 20 gpm, maintaining strong flow.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this cartridge fit my system and what are the basic specs?\u003c\/h3\u003e\n\u003cp\u003eThe Pentek DGD-5005-20 measures 20\" x 4.5\" and is sized to drop into any 20-inch Big Blue housing or other heavy-duty filter housings that accept 20\" x 4.5\" cartridges.

The Pentek DGD-5005-20 is aimed at homeowners, landlords, and light-commercial operators who need a reliable, high-capacity pre-filter for whole-house systems. It suits installations that require heavy-duty 20\" Big Blue housings, those working with higher-sediment wells, or anyone wanting longer cartridge life and lower pressure loss compared with conventional single-density sediment filters. Choose this cartridge when you want an NSF-tested, 5-micron sediment solution that balances flow, capacity, and cost-effectiveness.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does the DGD-5005-20 fit my 20\" Big Blue housing?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — it measures 20\" x 4.5\" and is designed to drop into any standard 20-inch Big Blue or similar heavy-duty housing.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How often should I change this sediment cartridge?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Change about every six months under normal conditions, or sooner if you see reduced flow or increased sediment in the water.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Pentek","offers":[{"title":"Default Title","offer_id":52909694320952,"sku":"B001VXW0U8","price":109.56,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1012\/6799\/6984\/files\/pentek-front-view-big-blue-20-inch.jpg?v=1788581872","url":"https:\/\/kelorix.ca\/products\/pentek-20-big-blue-sediment-filter-cartridge-dgd-5005-20-5-micron-dual-gradient-spun-polypropylene","provider":"Kelorix Canada | Shop Home, Electronics, Beauty, Toys \u0026 More","version":"1.0","type":"link"}
