System Integration
This PureT alkaline ORP filter is designed for post-filtration remineralization in reverse osmosis systems, under-sink filtration setups, and whole-home water treatment applications. Install after sediment and carbon filtration stages to restore beneficial minerals and adjust pH upward from acidic or neutral water. The 1/4" OD stem adapter makes it compatible with standard quick-connect tubing used in most residential RO systems. Use with a dedicated inline housing rated for 12" x 2.5" cartridges. Best performance when installed as a final polishing stage before dispensing or storage. Suitable for municipal or well water that has already been filtered for sediment and contaminants.
