We offer two replacement filter kits so you can get exactly what you need — and avoid paying for filters you don’t.

• Year 1 Kit found on this page (Includes RO Membrane):
  Ideal for your first full replacement, this kit includes all filters plus the RO membrane, which typically lasts up to 24 months.

• 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.
