Clean your household water and protect geysers, pumps and plumbing equipment with the MixBox 20 Inch Big Blue Sediment Filter Cartridge. Designed as a high-flow pre-filter, it effectively traps sand, sediment, silt and suspended particles commonly found in rainwater stored in JoJo tanks.
The dual-gradient density structure improves filtration efficiency from outer to inner layers, offering 3 times greater dirt holding capacity compared to standard sediment cartridges. It maintains minimal pressure drop even under sustained high flow, perfect for whole-house point-of-entry water systems.
Manufactured from pure food-grade polypropylene. It will not alter water taste, odour or colour during filtration.
Universal sizing fits all standard 20" × 4.5" Big Blue filter housings for simple direct replacement.
