3 x Refillable Resin Packs for DI-TUBE 2.0 - is the indicating resin that turns from Blue to Brown/Yellow when exhausted.
Once the resin is exhausted, it will change colour from a Blue/Green (when new) to a Brown/Yellow, which indicates a cartridge change is required. This is a gradual change and will occur over time. In NZ CITY WATER, you can obtain approximately 100 - 150 Litres of pure deionised Water from One Cartridge. Cartridge Life differs depending on the Conductivity/TDS of the incoming water supply.
NOTE: ALL 3 refill bags are to be used to pack the DITUBE. You will have a small amount left over (that is done on purpose). Pack the resin in and then use the sponges and white filters supplied to secure the resin in place.
