It offers 25-micron filtration with up to three times the dirt holding capacity of similar filters, fits all standard 20" Big Blue housings, and is NSF certified for reliable, long-lasting water purification. ## Description The Pentair Pentek DGD-7525-20 is a dual-gradient density sediment filter in the DGD Series, engineered for whole house water filtration in standard 20-inch Big Blue housings. Manufactured from 100% pure polypropylene, it will not impart taste, odor, or color to your water while providing dependable chemical compatibility. The 25 micron rating captures dirt, sand, silt, and other particulates and helps protect downstream filters, appliances, and plumbing.The dual-gradient density design progressively increases filtration from the outer surface to the inner core, combining pre-filtration and final filtration in a single cartridge. This delivers up to 3X the dirt-holding capacity of similar size sediment cartridges and greater capacity than standard spun or string-wound filters. The increased effective filter depth of 233% provides high particulate reduction efficiency at less than 1 psi pressure drop at 20 gpm, making the DGD-7525-20 an ideal high-flow pre-filter for high-demand applications.Fits all 20" x 4.5" Big Blue and heavy duty filter housings. NSF/ANSI Standard 42 certified for material requirements. Suitable for residential, municipal, rural, and commercial applications. Operating temperature: 40-145 degrees F. Replace every 6 months or when water pressure or quality decreases. Review: Every Day Use Just Have to Clean it Every 6 months - 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. Review: If you have the big blue 20 inch this is what you need. - Worked exactly as expected and good value for what it does. Fit the big blue water filter housing perfectly. ## 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 | #2,183 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #15 in Replacement Under-Sink Water Filters | | Brand | Pentek | | Brand Name | Pentek | | Customer Reviews | 4.7 out of 5 stars 2,359 Reviews | | External Testing Certification | NSF | | Global Trade Identification Number | 00700999877729 | | Included Components | 1 filter | | Item Dimensions D x W x H | 4.5"D x 20"W x 4.5"H | | 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 | 1.6 Pounds | | Manufacturer | Pentair | | Manufacturer Part Number | DGD-7525-20 | | Material | Polypropylene (PP) | | 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 Product Benefits Dual-Gradient Sediment Filter Cartridge is designed to reduce fine sediment in residential drinking wate See more | | Product Dimensions | 4.5"D x 20"W x 4.5"H | | UPC | 051678356432 700999877729 | | Unit Count | 1 Count | ## Product Details - **External Testing Certification:** NSF - **Item Weight:** 1.6 Pounds - **Material:** Polypropylene (PP) - **Product Dimensions:** 4.5"D x 20"W x 4.5"H ## Images ![Pentair Pentek DGD-7525-20 Big Blue Sediment Water Filter, 20-Inch, Whole House Dual-Gradient Density Spun Polypropylene Replacement Cartridge, 20" x 4.5", 25 Micron - Image 1](https://m.media-amazon.com/images/I/61vq46ooP1L.jpg) ![Pentair Pentek DGD-7525-20 Big Blue Sediment Water Filter, 20-Inch, Whole House Dual-Gradient Density Spun Polypropylene Replacement Cartridge, 20" x 4.5", 25 Micron - Image 2](https://m.media-amazon.com/images/I/81Nl6X4thyL.jpg) ![Pentair Pentek DGD-7525-20 Big Blue Sediment Water Filter, 20-Inch, Whole House Dual-Gradient Density Spun Polypropylene Replacement Cartridge, 20" x 4.5", 25 Micron - Image 3](https://m.media-amazon.com/images/I/71O4K2WiO3L.jpg) ![Pentair Pentek DGD-7525-20 Big Blue Sediment Water Filter, 20-Inch, Whole House Dual-Gradient Density Spun Polypropylene Replacement Cartridge, 20" x 4.5", 25 Micron - Image 4](https://m.media-amazon.com/images/I/61qZ6hYaZ4L.jpg) ![Pentair Pentek DGD-7525-20 Big Blue Sediment Water Filter, 20-Inch, Whole House Dual-Gradient Density Spun Polypropylene Replacement Cartridge, 20" x 4.5", 25 Micron - Image 5](https://m.media-amazon.com/images/I/71ZZBSPbwML.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 E***R on April 4, 2026* I use this filter for a small house and also for irrigation.
