Sediment Prefilter (Well Water)
The Sediment Prefilter cartridge is designed to reduce sediment content during the prefiltration stage. It is commonly used for well water supplies.

Sediment Prefilter (City Water)
The High Capacity Carbon/Sediment Prefilter cartridge is designed to reduce sediment and chlorine content during the prefiltration stage. It is most generally used for municipal water supplies or in cases where water is treated with chlorine.

Reverse Osmosis Membrane
The reverse osmosis membrane is the heart of the K5 Drinking Water Station and its design is exclusive to Kinetico. It is not a FlexFilter and does not need to be replaced regularly like FlexFilters.

Post Filter
A post filter is a final step in the water filtration process that removes any remaining impurities or contaminants. It is commonly used to provide high-quality, purified water for drinking, cooking, and other uses.

In addition to the 3 primary filters, your system also contains 2 auxiliary FlexFilters that allow us to customize it to target your specific requirements.
FlexFilters to target specific concerns
Target specific concerns
Besides the Purefecta Guard, other K5 auxiliary cartridges target additional issues you may have with your water.

The Mineral Plus is an additive cartridge that lets you add beneficial minerals such as magnesium and calcium to your treated drinking water.

Purfecta Guard
