Hydro-Logic Add On Kit De-Ionization for Stealth-RO

This deionization filter (DI) is designed to serve as a post, polishing stage for any Reverse Osmosis (RO) system. After an RO system, the product water may contain trace amounts of nitrates, phosphates, and silicates as well other total dissolved solids (TDS). Certain applications such as aquarium, medical, manufacturing and others require 99.99% ultra pure, 0 PPM water. This DI filter will remove any leftover contaminants giving you the purest H2O available.
