NSF certified for safety, it offers up to three times the dirt holding capacity of similar filters, effectively removing dirt, sand, and silt to protect your appliances and ensure clean, clear water. Replace every six months or when water pressure drops for optimal performance. ## 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. 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: Work as described - Work excellent and are as described. They're more expensive than they should be. ## 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 | | Brand | pentek | | Country of Origin | USA | | Customer Reviews | 4.7 out of 5 stars 312 Reviews | | Enclosure Material | Polypropylene (PP) | | External Testing Certification | NSF | | Global Trade Identification Number | 00700999877729 | | Included Components | 1 filter | | Item Dimensions D x W x H | 11.4D x 50.8W 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 | 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 | 11.4D x 50.8W x 11.4H Centimeters | | UPC | 051678356432 700999877729 | | Unit Count | 1.0 Count | ## Product Details - **Material:** Polypropylene (PP) - **Product Dimensions:** 11.4D x 50.8W x 11.4H Centimeters - **External Testing Certification:** NSF - **Product Benefits:** Dual-Gradient Sediment Filter Cartridge is designed to reduce fine sediment in residential drinking wate - **Brand:** Pentek ## Images ![Pentek 155356-43 20" 75/25 Micron Dual Gradiant Poly Cart - Image 1](https://m.media-amazon.com/images/I/61vq46ooP1L.jpg) ![Pentek 155356-43 20" 75/25 Micron Dual Gradiant Poly Cart - Image 2](https://m.media-amazon.com/images/I/81Nl6X4thyL.jpg) ![Pentek 155356-43 20" 75/25 Micron Dual Gradiant Poly Cart - Image 3](https://m.media-amazon.com/images/I/71O4K2WiO3L.jpg) ![Pentek 155356-43 20" 75/25 Micron Dual Gradiant Poly Cart - Image 4](https://m.media-amazon.com/images/I/61qZ6hYaZ4L.jpg) ![Pentek 155356-43 20" 75/25 Micron Dual Gradiant Poly Cart - Image 5](https://m.media-amazon.com/images/I/71ZZBSPbwML.jpg) ## 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 4 April 2026* I use this filter for a small house and also for irrigation.
