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.

By offering two kits, we make it easy to follow the recommended replacement schedule and reduce waste — so you only buy what your system truly needs.

*Filters may need to be replaced more often than indicated, depending on water contaminant levels and volume of water being treated.
