Choosing Cartridges for Each Stage
Any standard 4.5″ x 20″ cartridge fits. A common setup is a sediment filter first to catch sand and rust, then carbon stages to handle chlorine, taste, and odor. Browse our 4.5″ x 10″ Big Blue housing filters to match your water.
The same triple housing also works as a pre-filter stage ahead of a larger reverse osmosis system. Sediment and carbon cartridges here help protect the RO membrane from sand, rust, and chlorine.
