Replacement filters for G4 Countertop and Floor unit,
Replacement filters for G5 Under sink, Countertop and Floor unit, 
Additional filters and membranes for G3, G4, G5 units (please inquire directly for details to make sure your system has room to use additional or custom filters.

The G3, G4 and G5 Water Hydration Systems contain filters that should be replaced every 6-12 months. If your unit has an additional stage, that is the Reverse Osmosis Membrane or Ultra-Filtration Membrane, which should be replaced every 12-24 months.


Filters have a capacity load meaning they can only hold so many contaminants before in order to work efficiently. “Unloading” is a process that eventually occurs in every filter over time. Once saturated, the filter will allow small amounts of contaminants back into your water and may negatively impact the membrane's performance and water quality. To prevent that, your filters should be replaced as per the suggested schedule but you can purchase a TDS meter for RO systems to make sure you only replace your filters when it's time as the TDS will show you water quality and when to replace. 

Please replace carbon and sediment filters every 6-12 months to protect your membrane. RO members should be replaced every 2-3 years.
