Description
The Filters Fast® FFDG-20BB-5 Replacement Polypropylene Water Filter Cartridge is designed for 20-inch Big Blue whole house water filtration systems. Engineered with dual-density polypropylene media, it extends filter life by trapping larger particles in the outer layer and finer particles in the inner core. This high-capacity replacement helps protect plumbing fixtures, appliances, and downstream water treatment equipment from sediment buildup.
Key Benefits:
Compatible replacement for Pentek DGD-5005-20 and other standard 20″ x 4.5″ Big Blue filter housings.
Dual-gradient density design captures both large and fine sediment particles for longer service life.
5-micron nominal inner layer with 50-micron outer layer provides staged filtration for improved dirt-holding capacity.
High-capacity sediment filtration reduces sand, silt, rust, and scale before they reach plumbing and appliances.
100% polypropylene construction resists chemical attack and won’t impart taste, odor, or color to water.
Protects equipment such as water softeners, UV systems, and reverse osmosis systems from sediment buildup.
Cost-effective alternative to OEM filters while maintaining industry-standard sizing and performance.
