Finest-Filters Compact Reverse Osmosis RO Unit DI Deionisation Add On Stage with Resin, Tubing and Clips.

You are purchasing a add on De-ionisation kit for addition to any compact reverse osmosis unit. This extra filter stage will convert any 3 stage unit into a 4 stage unit, and the de-ionisation resin will reduce the TDS (total dissolved solids) within the product water further, resulting in ultra pure RO water. This unit can be opened and refilled with loose DI resin when required. This kit comes complete with a resin filled DI canister complete with 1/4" push fit fittings, 2 x clamps to connect DI vessel to RO unit, and 2m of 1/4" tubing to allow easy connection.
