Made from 100% pure polypropylene and NSF/ANSI 42 certified, it delivers superior dirt-holding capacity with minimal pressure drop, fitting all standard 20-inch Big Blue housings. Ideal for professionals seeking reliable, clean water without compromising flow or taste. ## 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: Works very well. I will buy it again. - The filter worked very well. The city did some water pipe repairs locally and mud came down the line. The filter was replaced by a plumber after only 3 days. A simple white filter was covered with dirt. The water quality in the house remained excellent. It saved a lot of money replacing fixtures etc. Review: Works good! - Went from a smaller micron to a bigger one in the same brand, plugged up right away, doesn’t make sense at all should have lasted longer ## Features - KEEP YOUR WATER CLEANER - Reduces dirt, sand, silt, and particulates and helps protect your appliances.

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 ### ⭐⭐⭐⭐⭐ Works very well. I will buy it again. *by L***E on 13 June 2025* The filter worked very well. The city did some water pipe repairs locally and mud came down the line. The filter was replaced by a plumber after only 3 days. A simple white filter was covered with dirt. The water quality in the house remained excellent. It saved a lot of money replacing fixtures etc. ### ⭐⭐⭐⭐⭐ Works good! *by M***E on 1 June 2022* Went from a smaller micron to a bigger one in the same brand, plugged up right away, doesn’t make sense at all should have lasted longer ### ⭐⭐⭐⭐⭐ Great Long Lasting Filter *by J***G on 28 November 2017* These dual media filters are incredible. I have a 3 stage system that is fed from lake water. This filter is my first stage, then I go down to 5 micron, then carbon, then UV. Compared to a standard 20 micron filter, I would say this one lasts about 3x as long before becoming plugged. If your water is rich in sediment or tannin, and your filters are plugging up fairly quickly, this may be a good option. You will still need something finer before UV, but its a great initial step. ## 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.kg/products/721778443-pentek-155356-43-20-75-25-micron-dual-gradiant-poly](https://www.desertcart.kg/products/721778443-pentek-155356-43-20-75-25-micron-dual-gradiant-poly) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-09-09*
