Designed for whole-house use, it fits all standard 20" Big Blue housings and offers up to 3 times the dirt holding capacity of similar filters. NSF certified for safety and performance, it effectively removes fine sediments down to 25 microns without affecting water taste or odor, making it ideal for residential and commercial applications. ## Description DGD Series Cartridges are manufactured from 100% pure polypropylene and are sized for use in Pentair Pentek Big Blue Filter Housings. DGD Series Cartridges are designed for purity and will not impart taste, odor or color to the liquid being filtered. Additionally, the polypropylene construction provides superior chemical resistance. The DGD Series' advanced design combines selective final filtration with appropriate pre-filtration to achieve up to three times the dirt holding capacity of similar size sediment cartridges and even greater capacity than standard spun or string-wound cartridges. The larger diameter of the filter reduces the particle load, allowing it to operate at higher velocities. The effective filter depth is increased to a full 233%. This increased depth provides very high particulate reduction efficiencies and added loading capacity. The design and performance characteristics of the DGD Series Cartridges make them an excellent choice for all residential, rural, municipal and commercial applications. ## Features - KEEP YOUR WATER CLEAN and protect your appliances by removing dirt, sand, silt and particulates - FITS ALL 20" Big Blue or other heavy duty housings and can replace any 20" x 4.5" sediment filter cartridge - ACHIEVES UP TO 3X the dirt holding capacity of similar size sediment cartridges - NSF CERTIFIED for your peace of mind - REPLACE EVERY 6 MONTHS or when you notice a drop in water pressure or quality ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B00207VSRA | | Best Sellers Rank | #40,742 in Tools & Home Improvement (See Top 100 in Tools & Home Improvement) #132 in Replacement Water Filters | | Brand Name | Pentek | | Customer Reviews | 4.7 4.7 out of 5 stars (340) 4.7 out of 5 stars | | External Testing Certification | NSF | | Global Trade Identification Number | 00700999877729 | | Included Components | 1 filter | | Item Dimensions D X W X H | 11.4D x 11.4W x 11.4H centimeters | | Item Type Name | Big Blue Sediment Water Filter, 20-Inch, Whole House Heavy Duty Dual-Gradient Density Spun Polypropylene Replacement Filter Cartridge, 20" x 4.5", 25 Micron | | Item Weight | 726 g | | Manufacturer | Pentair | | Manufacturer Part Number | DGD-7525-20 | | Material Type | Polypropylene (PP) | | Model Number | DGD-7525-20 | | Number Of Items | 1 | | Product Benefits | Dual-Gradient Sediment Filter Cartridge is designed to reduce fine sediment in residential drinking wate | | Set Name | Single | | Unit Count | 1.0 Count | | Upc | 051678356432 700999877729 | ## Product Details - **External testing certification:** NSF - **Item weight:** 726 g - **Material:** Polypropylene (PP) - **Product dimensions:** 11.4D x 11.4W x 11.4H centimeters ## Images ![Pentair 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 1, White - Image 1](https://m.media-amazon.com/images/I/61vq46ooP1L.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: what is the recommended manufacture filter change. or the life span of the filter how many gallons? Thanks** A: We have a lot of sediment and silt in our well water. I have been using these close to 10 years now, and I change them every 3 months. If I go too long, the silt gets past the filter and into the washing machine (that's where I notice it first). **Q: Will these filters fit the express water whole house filter hsg?they are also 4.5 x20 filters. Would like to use this gradiant sediment filter** A: Yes, the sediment filter will fit the 20 inch canister. That is a std size. It should go into the first position in a 3 canister setup. **Q: Can i replace a dgd-5005- 20 with this dgd-2501-20? what are the consequent's replace more often?** A: The DGD-2501-20 is designed to remove smaller particulate and is constructed of denser filter media than th DGD-5005-20, thus it my need to be replaced more often if the feed water quality has a higher volume of larger sized particulate. **Q: Where is this made?** A: The DGD-5005-20 Pentek is made in China. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Every Day Use Just Have to Clean it Every 6 months *by on Reviewed in the United States 4 April 2026* I use this filter for a small house and also for irrigation. It does a good job catching dirt and debris before it gets into the system. The filter gets dirty but the water stays clean. I usually clean it or change it about every six months depending on how dirty the water is. It has been working well so far and seems like good quality. ### ⭐⭐⭐⭐⭐ Effective sediment removal. High capacity. Does not impede water flow. *by on Reviewed in the United States 8 August 2026* Effective sediment filter. Keeps silt out of our arsenic removal tank and water softener tank. Does not impede water flow. Can't do without it when on well water. We change it every 90 days. ### ⭐⭐⭐⭐⭐ Work as described *by on Reviewed in Canada 8 April 2025* Work excellent and are as described. They're more expensive than they should be. ## 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 1, 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? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/309654016-pentair-dgd-7525-20-big-blue-water-filter-20-inch](https://www.desertcart.tn/products/309654016-pentair-dgd-7525-20-big-blue-water-filter-20-inch) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-20*
