Unlike traditional single-stage filters that rely heavily on a very fine mesh (like pleated filters or PP cotton), the Dual-Gradient cartridge employs two distinct zones within its filter media:

• Zone One: A coarser, water-stable layer designed to capture and hold the bulk of larger sediment particles – sand, silt, rust, mud, etc. This initial filtration prevents these large contaminants from even entering your secondary filters.
• Zone Two: A finer, high-efficiency zone that acts as a backup filter for smaller particles (down to very specific micron ratings depending on the media blend) and ensures consistent water clarity long after Zone One has done its job.     

Installing Pentek Dual-Gradient Sediment Cartridges protects: 

• Your downstream water filters (PP Cotton, Carbon, etc.) from premature clogging and damage.
• Your pressure tank by preventing sediment buildup inside it.
• Appliances like washing machines, icemakers, and especially your sensitive water heater, which can suffer from scale and efficiency issues due to suspended particles.
