It delivers 5-micron filtration with 3X the dirt holding capacity of similar filters, certified to NSF/ANSI Standard 42 for reliable contaminant reduction. Engineered for universal fit in all 20-inch Big Blue housings, it ensures superior sediment removal without affecting water taste or odor, making it ideal for residential and commercial use. ## 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. ## Features - KEEP YOUR WATER CLEAN and protect your appliances by removing dirt, sand, silt and particulates. DGD Big Blue water filter cartridges are designed for purity and will NOT impart taste, odor or color to your water - IDEAL HIGH-FLOW PRE-FILTER. Filter density increases toward the cartridge's center resulting in superior particulate reduction and 3X the dirt holding capacity of similar size sediment cartridges - TESTED AND CERTIFIED BY NSF INTERNATIONAL to NSF/ANSI Standard 42 for your peace of mind.
