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. ## Frequently Bought Together - Pentair Pentek DGD-2501-20 Big Blue Water Filter, 20-Inch Whole House Sediment Filter Cartridge Replacement, Dual-Gradient Density Spun Polypropylene, 20" x 4.5", 1 Micron, Pack of 6, 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, Whole House Heavy Duty Radial Flow Carbon Replacement Cartridge with Granular Carbon (GAC) Filter, 20" x 4.5", 25 Micron, Pack of 6, White --- ## 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.sg/products/672809609-pentair-pentek-dgd-2501-20-big-blue-water-filter-20](https://www.desertcart.sg/products/672809609-pentair-pentek-dgd-2501-20-big-blue-water-filter-20) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-10-23*
