    Pentek DGD-7525-20 water Filter Advantages

    The Pentek DGD-7525-20 water filters reduce the need for multiple housing step-down filtration systems. The Pentek DGD-7525-20 water filters are made of pure polypropylene construction and are resistant to chemicals and corrosion. The Pentek DGD-7525-20 replacement filters are designed for water purity along with bacteria and chemical resistance, the polypropylene material inhibits the growth of bacteria on the filter. The Pentek DGD-7525-20 water filter cartridge does not add taste, odor, or color to the liquid being filtered. The Pentek DGD-7525-20 water filter is ideal for all residential, rural, commercial, industrial, and municipal applications.

    Dual Gradient Density Filter Advantages

    The Pentek DGD-7525-20 outermost layer, the prefilter, reduces the particle load to the inner layer postfilter, allowing it to provide greater flow rates and retain more contaminants. By sifting out the particles by size as they flow through the filter media, there is less strain on the initial layer and a better distribution of contaminant reduction as water passes through the media. The effective DGD-7525-20 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.

    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.
