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


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.


This kit includes:

  • Purtrex 5 Micron Sediment Filter
  • MATRIKX CTO 5 Micron Carbon Block
  • 1.25 lb. Color Changing DI Resin Refill


Recommended Installation for this package*

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

*This is our recommended filter arrangement and we have found it 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 do not hesitate to call either store or email us and we will be happy to assist you.
