Made from 100% pure polypropylene, it removes coarse sediment like dirt, sand, silt, and rust without affecting water taste or odor. Certified to NSF/ANSI Standard 42, it offers up to three times the dirt-holding capacity of similar filters, fits standard 20" Big Blue housings, and maintains low pressure drop at high flow rates. Sold as a pack of two, it requires replacement every six months for consistent water quality. ## Description The Pentair Pentek DGD-7525-20 is a 20-inch dual-gradient density sediment cartridge that reduces dirt, sand, silt, rust, and other particulates across your whole house. Spun from 100% pure polypropylene, it is built for purity, will not impart taste, odor, or color to your water, and offers superior chemical resistance.The dual-gradient density design packs the spun fibers tighter from the outer surface toward the core, combining pre-filtration and final filtration in one cartridge. This increases the effective filter depth and delivers up to three times the dirt-holding capacity of similar-size sediment cartridges, so the filter lasts longer while holding pressure drop under 1 psi at 20 gpm.With a nominal 25 micron rating and 20" x 4.5" dimensions, it fits Pentair Pentek Big Blue and other heavy duty housings and replaces most 20-inch sediment cartridges. Tested and certified by NSF International to NSF/ANSI Standard 42 for material requirements. Replace every 6 months, or sooner if you notice a drop in water pressure or water quality. This listing is a Pack of 2. ## Features - KEEP YOUR WATER CLEANER - Reduces dirt, sand, silt, rust, and other sediment throughout your whole house so cleaner water reaches every tap; the 100% pure polypropylene media will not impart taste, odor, or color. - IDEAL HIGH-FLOW PRE-FILTER - Dual-gradient density construction grows denser from the outer wall toward the core, delivering up to 3 times the dirt-holding capacity of similar-size sediment cartridges for longer life between changes. - TESTED AND CERTIFIED BY NSF - Manufactured from 100% pure polypropylene and tested and certified by NSF International to NSF/ANSI Standard 42 for material requirements, at a nominal 25 micron rating for coarse sediment. - SIZED FOR 20-INCH BIG BLUE HOUSINGS - Drops into any 20" x 4.5" Big Blue or heavy duty whole house housing and replaces most 20-inch sediment cartridges, with a low pressure drop under 1 psi at 20 gpm. - REPLACE EVERY 6 MONTHS - Swap the cartridge every 6 months, or sooner when you notice a drop in water pressure or water quality; filter life varies with your incoming water conditions. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CJCWRRVH | | Best Sellers Rank | #2,435 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #18 in Replacement Under-Sink Water Filters | | Brand Name | Pentek | | Customer Reviews | 4.6 4.6 out of 5 stars (253) | | External Testing Certification | ANSI | | Global Trade Identification Number | 50051678356437 | | Item Dimensions D x W x H | 4.5"D x 4.5"W x 20"H | | Item Highlight | Whole House Spun Polypropylene Sediment Cartridge; 20" x 4.5", 25 Micron, 3X Dirt-Holding, NSF/ANSI 42, Fits Big Blue | | Item Type Name | Pentair Pentek DGD-7525-20 Big Blue Water Filter | | Manufacturer | Pentair | | Manufacturer Part Number | 155356-44 | | Material Type | Polypropylene (PP) | | Model Number | DGD-7525-20 | | Number of Items | 2 | | Product Benefits | Protects appliances by removing impurities, high-flow pre-filter, third-party tested and certified, compatible with various filter housings | | Unit Count | 2 Count | ## Product Details - **Brand:** Pentek - **External Testing Certification:** ANSI - **Material:** Polypropylene (PP) - **Product Dimensions:** 4.5"D x 4.5"W x 20"H ## Images ![Pentair Pentek DGD-7525-20 Big Blue 20-Inch Sediment Filter, Pack of 2 - Image 1](https://m.media-amazon.com/images/I/51D0z2TV99L.jpg) ## Available Options This product comes in different **Size, Style** options. ## Frequently Bought Together - Pentair Pentek DGD-7525-20 Big Blue Water Filter, 20-Inch Whole House Sediment Filter Cartridge Replacement, Dual-Gradient Density Spun Polypropylene, 20" x 4.5", 25 Micron, Pack of 2, White - Captain O-Ring - Replacement 151122 O-Rings Compatible with Pentair Pentek Big Blue Water Filters OEM Size ORing Buna-N (3 Pack) - Pentair Pentek RFC-20BB Big Blue Carbon Water Filter, 20-Inch, Whole House Heavy Duty Radial Flow Carbon Replacement Cartridge with Granular Activated Carbon (GAC) Filter, 20" x 4.5", 25 Micron --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/586533105-pentair-pentek-dgd-7525-20-big-blue-20-inch-sediment](https://www.desertcart.co.za/products/586533105-pentair-pentek-dgd-7525-20-big-blue-20-inch-sediment) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-11-10*
