    Details

    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

     

    Our filter kits feature some of the most widely used and trusted brands in the world including GE, KX Technologies and Pentek. The 10” filter size is the industry standard and will fit our systems as well as virtually every brand of RO system that uses similar looking carbon blocks.  Most of the filters included in our kits are NSF Certified or WQA Gold Seal Certified and Manufactured using FDA-compliant materials.

     

    *This is our recommended filter arrangement and we have found to be the best combination for the most common installations and water conditions. If you have something unique about your water supply or installation please contact customer service and one of our WQA certified water specialists will be able to assist you. Our onsite chat feature is the quickest way to receive advice but we are available to assist via the phone and email as well.
