20” x 4.5” Big Blue Whole House Water Filter Sediment Carbon Cartridge | 5-0.5 Micron | Replacement for Town Water
High-Performance Filtration for PFAS & Chloramine Removal with Grooved Sediment Filter
Upgrade your whole house filtration system with this 20” x 4.5” Big Blue Water Filter Cartridge Set, specially engineered for effective removal of sediment, PFAS, chloramine, chlorine, and VOCs in town water. This dual-stage high-performance filter combination delivers cleaner, safer, and better-tasting water throughout your home. The grooved surface sediment filter increases capacity and flow, while the catalytic carbon block provides targeted contaminant removal.
The sediment filter’s grooved surface expands filtration area by up to 60%, capturing coarse particles on the outer layer and finer sediments internally. The 0.5-micron carbon filter utilizes catalytic activated carbon to effectively reduce chloramine and PFAS, which are commonly found in Australian municipal water supplies.
