    This kit works with all BRS 4 Stage RO Only Systems along with most other RO systems that use 10" canisters.

    This kit includes:

    • Purtrex 5 Micron Sediment Filter
    • MATRIKX CTO 5 Micron Carbon Block
    • MATRIKX CTO 1 Micron Carbon Block

    We recommend changing sediment filters when they become visually dirty or there is a noticeable drop in pressure. Change carbon blocks every 6-12 months depending on use. This kit does not include a membrane filter as they need replacement every three years or so, depending on water and set up.


    Recommended Installation*

    • Stage One - Purtrex 5 Micron Sediment Filter
    • Stage Two - MATRIKX CTO 5 Micron Carbon Block
    • Stage Three - MATRIKX CTO 1 Micron Carbon Block
