BRS Matrikx 6 Stage RO/DI Replacement Filter Kit

This kit works with all BRS 6 Stage RO/DI or 5 Stage RO/DI Systems along with most other RO/DI systems that use 10" canisters. If your water supply is off a well, or your city uses chlorine to treat the water, Matrix Filters are a great value option and will effectively prepare your water for filtration through the membrane and also scrub the water of any remaining TDS after the membrane with the included Nuclear Grade DI Resin. If your city uses chloramines, we do suggest using the BRS 6 Stage RO/DI Replacement Filter Kit.

Kit includes:

  • Purtrex 5 Micron Sediment Filter
  • MATRIKX CTO 5 Micron Carbon Block
  • MATRIKX CTO 1 Carbon Block
  • 2x - 1.25 lb. Color Changing DI Resin Refills


Recommended Installation for this package*

  • Stage One - Purtrex 5 Micron Sediment Filter
  • Stage Two - MATRIKX CTO 5 Micron Carbon Block
  • Stage Three - MATRIKX CTO 1 Micron Carbon Block
  • Last Stages - DI Resin Refills


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.


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 NSF Certified or WQA Gold Seal Certified and Manufactured using FDA-compliant materials.
