AquaticLife RO Buddie reverse osmosis filter cartridges come in a pack with a Carbon Block Filter, a Sediment Cartridge, and a Color Changing Deionization Resin.
The 5 Micron Sediment Filter Cartridge removes particulate material from water like sand, silt, and rust to improve water taste and appearance.
The 5 Micron Activated Carbon Block Filter Cartridge removes 1 PPM chlorine and conditions water before the RO Membrane.
The Mixed-Bed Deionization Filter Cartridge removes remaining TDS from membrane-filtered water and changes colors from Blue to Tan when depleted.
These RO replacement filters are compatible with AquaticLife RO/RODI units and also work with other RO, RODI brands.
