4.5″ x 20″ Dual Gradient Sediment Filter

The 4.5″ x 20″ Dual Gradient Sediment Filter (25/1 Micron) is engineered for superior sediment removal and extended filter life. Designed with two layers of filtration, this filter captures larger particles like sand, rust, and dirt in the outer 25-micron layer while the inner 1-micron core targets finer sediment. The result is more efficient filtration and longer-lasting protection for your plumbing and appliances.

Ideal for whole-house systems, this filter fits most standard 20″ big blue housings and is especially effective in homes with well water or high sediment loads. Its gradient density design not only improves performance but also helps reduce pressure drop across the system.
