The Pentek DGD-7525 water filters have two separate gradient density layers that enhance cartridge performance. The Pentek DGD-7525 larger diameter of the pre-filter reduces the particle load to the post filter, allowing it to operate at higher velocities. The effective DGD-7525 filter depth is increased to a full 233% of standard spun-polypropylene or string-wound filters. This increased depth provides for very high particulate reduction efficiencies and added loading capacity. The Pentek DGD-7525 filter cartridge has a 75 micron pre-filter fine sediment water filter layer and a 25 micron post-filter extra-fine sediment water filter layer. The Pentek DGD-7525 water filters are pure polypropylene construction resistant to chemicals and corrosion. The Pentek DGD-7525 water filter cartridge will not add taste, odor, or color to the liquid being filtered. The Pentek DGD-7525 replacement filters are designed for purity, bacteria resistance, and chemical resistance. The Pentek DGD-7525 water filter has three times the dirt-holding capacity of similar sized sediment water filter cartridges. Replace the Pentek DGD-7525 sediment water filter cartridge every 2 months or 8,000 gallons of water. The filter change interval also depends on your water supply and water usage.
