Year 2 Kit (Without RO Membrane): After the first year, you only need to replace the pre- and post-filters, since the RO membrane is still good for another year. This kit helps you save money while keeping your system performing like new. *Filters may need to be replaced more often than indicated, depending on water contaminant levels and volume of water being treated.
