- Matrikx 5 Stage RO/DI Replacement Filter Kit
This kit works with all BRS 5 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
- MATRIKX CTO 1 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
- Stage Three - MATRIKX CTO 1 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.

Worked as expected By Mark on 9/21/2017Mark would recommend this product to a friendBeen a few years since I have run my RO/DI system and I was a bit nervous it may not work anymore. Bought all new filter media and the filters worked perfectly. Great item.
Great value By Ron on 6/21/2017Ron would recommend this product to a friendGreat price for a nice 5-stage filter kit. Have purchased this kit several times and it will continue to be my go to replacement kit.
great value By denbf58 on 4/15/2017denbf58 would recommend this product to a friendgreat price and quality product what more needs to be said
Great Product By DK on 1/13/2017DK would recommend this product to a friendGreat product and cheaper than other places. The DI resin was a little messy to replace but well worth the trouble to save a little cash.

Quick delivery & well marked filter packaging. By Roco on 7/14/2015Roco would recommend this product to a friendReceived the package well before it was expected which allowed me to service the unit in our timeline. The price was very reasonable. The shipping box could have been a bit more substantial.
Great Product By JB on 5/17/2015JB would recommend this product to a friendCan not get a better deal on RO DI items. Work great.
I own the standard RO unit with the DI, it's been roughly a year and I'd like to replace the necessary components in which need to be replaced within this time. Is this the correct kit to purchase? Thank you kindly.
If you have the 5 stage standard unit this would be exactly the filter kit you would need!
In your opnioin about how often should the filters be changed. My TDS meter consistently reads 3 or 4 on the inlet prior to my DI resin and my DI resin needs to be changed about every 6 months so just wondering about the other filters.
At the least the prefilters should be replaced yearly but it really comes down to usage. The carbon blocks are good for 6000g of total water (which is waste + product) and the sediment filters should be replaced when they become dirty/clogged. If either is clogged it would generally be visible by a decrease of water pressure on an RO/DI pressure gauge.
I have the 5 stage ro system. I need replacement filters but I am not sure exactly what I need. I see the kit for the five stage unit. The kit includes a bag of resin. What chamber is that for. Thanks.
If you have our 5 stage RO/DI system then you would want the 5 stage RO/DI replacement filter kit. The bag is the bag of DI resin which replaces the DI resin on your RO/DI unit (the last stage).
Hello, when do you expect to have more of these back in stock? Or, is there another 5 stage RODI refill that will work (although this is the only one I've ever used)?
We are currently waiting on more resin to be in stock, should be the end of this week/early next week.
Does this kit come with a replacement ro membrane? Says 5 stage kit but I only see 4 items listed.
This kit will replace the pre-filters and DI resin in a 5 stage system, but will not come with the RO membrane as that needs to be replaced less frequently. If you need to replace the RO membrane as well those can be found at the link below. Have a great day!
I don't have a brs rodi unit, will this work with mine? I have an aquafx unit
RO filters are pretty much universal. They will work with your Aquafx unit as well as just about any other unit out there :-)
Hi, I have The BRS 4 stage value water saver plus Ro/do 150gpd. I am needing to change all filters. Which filter set do I need?
You will want the 4 stage value replacement filter kit (link below) and possibly the replacement 75 GPD membranes.
I have Spectrapure 4 stage Rodi system. It's 16" canisters. You think I'll be available to use this matriks as a replacement for my unit!?
I purchased the 5 stage drinking and reef filter kit and I was wondering why im missing a filter. I have a 5 stage drinking filter system with the one di filter that is separate from the drinking unit. The replacements came with a di package, 5 micron, purtrex 05 micron, chlorine taste and odor reduction, and a .6 micron. When should I replace the other filter and where can I purchase it?
The filter that isn't included in the kit (which is different then this one, sounds like you have the 5 stage drinking and reef water replacement filter kit) is the 75gpd RO membrane. They only need to be replaced every 3-5 years, or often even much longer if you treat them nicely. They can be found right here in the future:
It says 5 stage yet on full description I see one, two, three, and last. That only makes 4 stages how is it 5 I bought this unit used from someone and I dont quite understand the 5 stages with 4 containers.
When you replace the filters in the unit you generally don't replace the RO membrane until about 2-3 years. The replacement 5 stage filter kit is meant for the 5 stage RODI, it just does not come with the RO membrane, just the sediment, carbon blocks and a refill of resin.
I have the 5 stage plus system. I've produced about 10 gal a month since new April 2011. The TDS meter still reads 0 and pressure is good, but they're green, black, and brown. Do I need to replace my filters?
Its best practice to replace the sediment filters and carbon blocks yearly if nothing else. Filters like the carbon blocks serve other functions like removing chlorine (which otherwise damage the membrane) and won't show up as TDS when they are depleted. Changing them on a regular basis ensures your not damaging the much more expensive membrane which otherwise should last 3-5 years or even longer.
I have the five stage BRS rodi unit. I've noticed two things:
1) I last purchased filters a few months ago. The sediment filter is a very very light brown. Yet, counter intuitively, I am seeing the pressure rise. I can easily hit 100PSI, unless I dial my kitchen sink back to about 25% output. Is this normal?
2) I've owned the entire unit for several years. In that entire time, I've never seen anything more than 1 TDS for the inlet and 0 for the outlet. No matter how long the unit goes without servicing, that seems unlikely. Is the meter faulty?
1) Eventually that sediment filter will need changing as it gets very filthy, but if the pressure is increasing that's simply because the input water is. High pressure is a good thing but you do want to turn the sink down to keep it under 80.
2) The TDS meter on the unit measures the input of the DI (which is actually the output of the membrane) and the output of the DI. Considering your high water pressure and the fact that the water has already gone through 4 of the 5 stages of filtration, its not that unsual to see a number like 0-1 on the "in" side of the DI resin. Its likely just an indicator that your tap water was fairly low in TDS to begin with. The fact that the output number reads 0 and the resin hasn't turned entirely yellow also support this. Its a good thing, most folks would love to experience this!
