20" Big Blue Pre-Sediment Filter Cartridge

First-stage 20" Big Blue pre-sediment cartridge that captures sand, silt, rust and suspended particles before they reach your carbon and polishing stages — protecting downstream filters and keeping water clear. Fits all standard 20" Big Blue housings.

Choose the Eco range for everyday municipal water, or the Premium 20-micron range for finer particle capture. Recommended replacement every 6 months or 3,500 L, depending on water quality.
