Recently we introduced our newest pure water system, the Tucker® S4.
This is an upgraded system over the prior Tucker® 3 stage cart because it now has 4 stages of filtration.
Sediment and carbon filtration rather than just carbon.
This dual clear housing comes complete with the sediment and carbon filter (not pictured).
To upgrade your 3 stage cart to a 4 stage simply remove the bracket and carbon pre-filter from your 3 stage and install this bracket and filters in their place. The hardware that is currently holding your carbon pre-filter bracket in place will hold this new bracket in place so no need for any additional hardware.
