Certified by NSF to Standard 42, it delivers ultra-fine 1 micron filtration with 3X the dirt holding capacity of typical filters, ensuring cleaner water without compromising taste or odor. Ideal for all 20" Big Blue housings, this pack of 6 filters offers long-lasting, high-flow performance for residential and commercial use. ## Description The Pentair Pentek DGD-2501-20 is a 20-inch dual-gradient density sediment cartridge with a fine nominal 1 micron rating, built for whole-house, point-of-entry filtration. Spun from 100% pure polypropylene, it reduces fine dirt, sand, silt and rust, adds no taste, odor or color to your water, and offers broad chemical compatibility. Its dual-gradient design packs the fibers more tightly from the outer surface toward the core, raising effective filter depth to a full 233% and delivering up to three times the dirt-holding capacity of similar-size cartridges, with a low pressure drop under 1 psi at 20 gpm. Measuring 20" x 4.5", it fits all 20-inch Big Blue and other heavy-duty housings and replaces any 20" x 4.5" sediment cartridge, handles temperatures to 145Β°F, and is tested and certified by NSF International to NSF/ANSI Standard 42 for material requirements. This six-pack keeps spares on hand; replace about every 6 months, or sooner when flow or water quality drops. ## Features - KEEP YOUR WATER CLEANER - Reduces fine dirt, sand, silt, rust and other sediment to help protect your appliances, plumbing and downstream filters. Made from 100% pure polypropylene, it will not impart taste, odor or color to your water. - FINE 1 MICRON PRE-FILTER - Dual-gradient density increases filter density from the outer surface to the core, delivering up to 3X the dirt-holding capacity of similar-size cartridges and 233% greater effective filter depth. - TESTED AND CERTIFIED TO NSF/ANSI 42 - Independently tested and certified by NSF International to NSF/ANSI Standard 42 for material requirements. Manufactured from 100% pure polypropylene for purity and broad chemical compatibility. - FITS ALL 20-INCH BIG BLUE HOUSINGS - Drops into any 20" Big Blue or other heavy-duty housing and replaces any 20" x 4.5" sediment cartridge, with a low pressure drop under 1 psi at 20 gpm for strong whole-house flow. - REPLACE EVERY 6 MONTHS - Change the cartridge about every six months, or sooner when you notice a drop in water pressure or water quality.

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 ### ⭐⭐⭐⭐⭐ Effective sediment removal.
