Pentek DGD-2501-20 Filter Advantages

The Pentek DGD-2501-20 water filter has two separate gradient density layers that enhance cartridge performance. The prefilter (outer density layer) reduces the particle load to the postfilter (inner density layer), allowing it to operate at higher velocities/ higher flow rates. The effective DGD-2501-20 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-2501-20 water filter cartridge will not add taste, odor, or color to the liquid being filtered. This water filter has three times the dirt-holding capacity of similar sized sediment water filter cartridges. The Pentek DGD-2501-20 water filter is ideal for all residential, rural, commercial, industrial, and municipal applications.

Pentek DGD-2501-20 Contaminant Reduction

The Pentek DGD-2501-20 water filters reduce the need for multiple housing step-down filtration systems. The Pentek DGD-2501-20 filter cartridge reduces extra fine dirt, sand, sediment, silt, rust particles, and scale particles. The Pentek DGD-2501-20 water filter is made from pure polypropylene construction making it highly resistant to chemicals and corrosion. This replacement 20 x 4.5 inch filter is designed for water purity and bacterial and chemical resistance. The Pentek DGD-2501-20 filter cartridge has a 25 micron fine sediment prefilter layer and a 1 micron extra fine sediment postfilter layer.

Polypropylene Filter Media

Polypropylene media inhibits bacterial growth making it an ideal option for both municipal and well water applications. These filters are effective at capturing contaminants such as sand, sediment, silt, and more. Unlike carbon filter cartridges you wont have to worry about small carbon fines potentially spilling into your water, while still enjoying the benefits of filtered water throughout your home. Polypropylene filters are great for whole house water filtration and can be used as effective pre-filters for whole house or point of use systems.
