Engineered with premium melt-blown polypropylene fiber, this 5-micron replacement filter delivers superior sediment removal with up to 20% longer service life than standard sediment filters.\u003c\/p\u003e\n\n\u003ch2\u003ePremium Melt-Blown Polypropylene Construction\u003c\/h2\u003e\n\u003cp\u003eUnlike cheaper spun or string-wound sediment filters, this NU Aqua filter is manufactured using advanced melt-blown polypropylene technology. This process creates a true depth filter with graduated density—tighter filtration at the core and more open structure at the surface. The result is exceptional dirt-holding capacity, longer filter life, and consistent performance throughout the filter's lifespan.\u003c\/p\u003e\n\n\u003ch2\u003e5 Micron Filtration for Whole Home Protection\u003c\/h2\u003e\n\u003cp\u003eThe 5-micron rating provides the ideal balance between fine filtration and water flow for whole house applications. This filter effectively captures sand, silt, rust, scale, and other particulates that can damage water heaters, clog fixtures, stain laundry, and reduce the effectiveness of downstream filters. It's the essential first line of defense for any whole house water treatment system.\u003c\/p\u003e\n\n\u003ch2\u003e20% Longer Service Life\u003c\/h2\u003e\n\u003cp\u003eThanks to the high-capacity melt-blown construction, this premium sediment filter holds significantly more dirt and sediment than standard filters. The graduated density design allows the filter to load evenly throughout its depth, extending service life by up to 20% compared to conventional sediment filters. This means fewer filter changes, lower maintenance costs, and better long-term value.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features \u0026amp; Benefits\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePremium Melt-Blown PP\u003c\/strong\u003e - Superior construction for maximum dirt-holding capacity\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e5 Micron Filtration\u003c\/strong\u003e - Captures fine sediment, rust, sand, and particulates\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e20% Longer Life\u003c\/strong\u003e - Extended service life reduces replacement frequency and costs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard 4.5\" x 20\" Size\u003c\/strong\u003e - Universal fit for big blue and standard 20\" housings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGraduated Density\u003c\/strong\u003e - True depth filtration for even loading and consistent flow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhole Home Protection\u003c\/strong\u003e - Filters water at point of entry for complete coverage\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Flow Rate\u003c\/strong\u003e - Maintains strong water pressure throughout your home\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChemical-Free\u003c\/strong\u003e - Pure polypropylene construction, no binders or adhesives\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhat It Removes\u003c\/h2\u003e\n\u003cp\u003eThis 5-micron sediment filter effectively captures:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSand and silt (down to 5 microns)\u003c\/li\u003e\n\u003cli\u003eRust and oxidized iron particles\u003c\/li\u003e\n\u003cli\u003eScale and mineral deposits\u003c\/li\u003e\n\u003cli\u003eSediment and dirt\u003c\/li\u003e\n\u003cli\u003ePipe debris and particulates\u003c\/li\u003e\n\u003cli\u003eTurbidity and cloudiness\u003c\/li\u003e\n\u003cli\u003eWell water sediment\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eProtects Your Entire Home\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Heaters\u003c\/strong\u003e - Prevents sediment buildup that reduces efficiency and shortens lifespan\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAppliances\u003c\/strong\u003e - Protects dishwashers, washing machines, and ice makers from damage\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFixtures\u003c\/strong\u003e - Prevents clogging of faucet aerators, showerheads, and valves\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlumbing\u003c\/strong\u003e - Reduces sediment accumulation in pipes and water lines\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDownstream Filters\u003c\/strong\u003e - Extends life of carbon filters, RO membranes, and other treatment stages\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLaundry\u003c\/strong\u003e - Prevents rust stains and sediment on clothes\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eUniversal Big Blue Compatibility\u003c\/h2\u003e\n\u003cp\u003eThe standard 4.5\" x 20\" dimensions make this filter compatible with all major big blue filter housings, including NU Aqua whole house systems, Pentek, Culligan, iSpring, and other brands using standard 20-inch housings.

The premium melt-blown polypropylene construction delivers consistent filtration, high dirt-holding capacity, and extended service life that commodity filters can't match. When you choose genuine NU Aqua replacement filters, you're ensuring your whole house system operates at peak efficiency while protecting your investment in plumbing and appliances.\u003c\/p\u003e\n\n\u003ch2\u003ePerfect For\u003c\/h2\u003e\n\u003cp\u003eIdeal for municipal water with sediment issues, well water applications, homes with older plumbing that sheds rust and scale, pre-filtration for RO systems and water softeners, and as the first stage in any whole house water treatment system. Essential protection for homes with high sediment loads or variable water quality.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eInstallation Tip:\u003c\/strong\u003e Always install sediment filters as the first stage in your whole house system, before carbon filters or other treatment stages. This protects downstream filters and extends their service life. Shut off water supply before replacing filters.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eMaintenance Recommendation:\u003c\/strong\u003e For optimal performance, replace sediment pre-filters every 3-6 months depending on your water quality. Homes with well water or high sediment loads may require more frequent changes. Monitor pressure drop across the filter to determine optimal replacement timing.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSystem Design Tip:\u003c\/strong\u003e For best results, use this 5-micron sediment filter as a pre-filter before carbon filters, water softeners, or RO systems. If you have very high sediment loads, consider adding a 20-micron sediment filter before this 5-micron stage for extended filter life.\u003c\/p\u003e","brand":"NU Aqua","offers":[{"title":"Default Title","offer_id":41826667561047,"sku":"WU-S20-5M","price":39.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1555\/0581\/files\/Whole-House-System-NUAqua-Sediment-Main-WithLabel_600x_13cb2b03-e2b5-431a-abce-109f42aa3606.webp?v=1753136945","url":"https:\/\/getultimatenow.com\/products\/nu-aqua-4-5x20-whole-house-sediment-filter-5-micron-big-blue","provider":"Get Ultimate Now ","version":"1.0","type":"link"}
