It delivers 1-micron filtration precision, removing fine sediment without affecting water taste or odor. Certified to NSF/ANSI Standard 42, it offers 3X the dirt holding capacity of typical filters and fits all standard 20-inch Big Blue housings, making it a reliable, heavy-duty solution for residential and commercial water purification needs. ## Description The Pentair Pentek DGD-2501-20 is a 20-inch Big Blue whole-house sediment cartridge built on the DGD Series dual-gradient density design. Spun from 100% pure polypropylene, it reduces dirt, sand, silt, and rust down to a nominal 1 micron while adding no taste, odor, or color to your water.The dual-gradient structure increases filter density from the outer surface toward the center, so coarse particles are captured on the outside and finer particles deeper in. This delivers up to three times the dirt-holding capacity of similar-size cartridges and a very low pressure drop of under 1 psi at 20 gpm, making it an excellent high-flow pre-filter ahead of carbon or specialty filters.Measuring 20" x 4.5", it fits all 20-inch Pentair Pentek Big Blue and other heavy-duty housings and is tested and certified by NSF International to NSF/ANSI Standard 42 for material requirements. Replace approximately every 6 months, or sooner if flow drops. Ships as a single cartridge. ## Features - KEEP YOUR WATER CLEANER - Reduces dirt, sand, silt, and rust particles to help protect your appliances, water heater, and plumbing; spun from 100% pure polypropylene that will not impart taste, odor, or color to your water. - IDEAL HIGH-FLOW PRE-FILTER - Dual-gradient density traps coarse particles on the outer surface and fine particles toward the core, delivering up to 3X the dirt-holding capacity of similar-size sediment cartridges with very low pressure drop. - TESTED AND CERTIFIED - Rated at a nominal 1 micron and tested and certified by NSF International to NSF/ANSI Standard 42 for material requirements; polypropylene construction gives excellent chemical compatibility. - SIZED FOR BIG BLUE HOUSINGS - Measures 20" x 4.5" and fits all 20-inch Pentair Pentek Big Blue and other heavy-duty housings; drops in to replace any 20" x 4.5" sediment cartridge. - REPLACE EVERY 6 MONTHS - Change about every 6 months, or sooner when you notice a drop in water pressure or water quality; low initial pressure drop under 1 psi at 20 gpm keeps flow high. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00207SAEY | | Best Sellers Rank | #5,982 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #1 in Industrial Process Filter Cartridges | | Brand Name | Pentek | | Customer Reviews | 4.7 4.7 out of 5 stars (821) | | External Testing Certification | NSF, ANSI | | Global Trade Identification Number | 00051678360439 | | Included Components | Sediment Water 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", 1 Micron | | Item Weight | 0.27 g | | Manufacturer | Pentair | | Manufacturer Part Number | 155360-43 | | Material Type | Polypropylene (PP) | | Model Number | DGD-2501-20 | | Number of Items | 1 | | Product Benefits | Dual-Gradient Sediment Filter Cartridge is designed to reduce fine sediment in residential drinking wate | | Set Name | Single | | UPC | 182682387591 851905131418 051678360439 643749296343 163120791262 | | Unit Count | 1 Count | ## Product Details - **External Testing Certification:** NSF, ANSI - **Item Weight:** 0.27 g - **Material:** Polypropylene (PP) - **Product Dimensions:** 4.5"D x 20"W x 4.5"H ## Images ![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 1, White - Image 1](https://m.media-amazon.com/images/I/61g2k9qKloL.jpg) ![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 1, White - Image 2](https://m.media-amazon.com/images/I/21JnPUvQfXL.jpg) ![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 1, White - Image 3](https://m.media-amazon.com/images/I/517IL9S27DL.jpg) ![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 1, White - Image 4](https://m.media-amazon.com/images/I/41QkK4oob3L.jpg) ![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 1, White - Image 5](https://m.media-amazon.com/images/I/41pRfHQlkGL.jpg) ## Available Options This product comes in different **Size, Style** options. ## 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 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?
