- Matrikx 4 Stage RO/DI Replacement Filter Kit
This kit works with all BRS 4 Stage RO/DI Systems along with most other RO/DI systems that use 10" canisters.
This kit includes:
- Purtrex 5 Micron Sediment Filter
- MATRIKX CTO 5 Micron Carbon Block
- 1.25 lb. Color Changing DI Resin Refill
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 for this package*
- Stage One - Purtrex 5 Micron Sediment Filter
- Stage Two - MATRIKX CTO 5 Micron Carbon Block
- Last Stage - DI Resin
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.

I ordered a 4 stage replacement filter kit and got the bag of stuff. Where does it go? I dont have a cartridge that opens and lets me fill it with anything
Do you have our 4 stage RO/DI filter system? If so, the last stage to the right is the DI stage. When you remove that canister the bottom will screw off the cartridge inside of it allowing you to replace the resin.
Will these cartridges work to replace filters on a Coralife Pure-flo II 50 gpd system?
Our filters are universal 10" filter sizes that will fit almost any unit on the market (including the Coralife). Keep in mind that we package our DI resin in vacuum sealed bags to be used with refillable cartridges. If your DI cartridge isn't refillable youll want to pick up a refillable one the first time as well (sku 200002).
I upgraded my 75 GPD RO/DI unit to 150GPD. I recently purchased replacement filters due to seeing green algae inside the filters and housings. I changed out and rinsed out as much as I could when changing filters and DI resin. However, I am seeing more algae starting to show again. I took ALL filters out and ran some clorox water thru the system, then flushed it with clean clear water. My system is located under a deck outside my laundry room. It gets no direct sun. What can I do to stop the algae? Should I drain the filter canisters when not using it? I ran clorox thru since I figured the 1/4 tubing maybe have algae contamination.
Even though your system may not be getting direct sun it is still receiving enough light to support algae. I would place it in a cabinet or cover the canisters to completely shield it from the sun. This should be enough to prevent algae growth.
Running bleach through the system should kill any algae spores but it will also damage your RO membranes and quickly exhaust your carbon filters which are now likely contaminated with algae. Its also possible that your tap water contains enough algae to contaminate your system so this could be a never ending battle in your current situation.
Before running any more bleach through the system I would try the first solution and go from there.
I hope this helps!
Have a great day :)
