The DGD-2501-20BB Dual-Gradient Polypropylene Filter is a 2-in-1 filter that works as both a pre- and post-filter. The outer layer of this filter is a 75 micron pre-filter that captures larger sediment, reducing the load on the 25 micron inner-layer post filter, which allows it to operate more efficiently and further improve water quality. Its polypropylene construction has a strong resistance to chemicals and corrosion.
