Replacement Filter Cartridges
To ensure optimum performance, continued warranty coverage and that your
system continues to comply with NSF certification standards, you must replace
the prefilter and postfilter cartridges annually. Replace the RO membrane
cartridge when the system stops adequately reducing TDS. TDS performance
can be measured by your authorized Kinetico dealer. Use the following chart to
determine which filters are appropriate for your system.
