- BRS 4 Stage Value Replacement Filter Kit
Why does BRS recommend this?
For almost all 4 Stage RODI systems we recommend the BRS 4 Stage Value replacement filter kit. This kit included high quality filter elements including the Purtrex 1 micron sediment filter and BRS Universal Carbon. We would be very wary of using cheap, low quality carbon blocks in a 4 Stage RODI system because they do not last as long and will start to let organics and chlorine though very quickly. The kit also includes Color Changing DI resin which comes in a vacuum sealed Mylar bag for a long shelf life and effectiveness.
This kit is designed to treat all major water sources including well water and water treated with chloramines or chlorine. The 4 stage Value Replacement Filter Kit has been upgraded with the latest in carbon block technology and the best four stage RO/DI solution to universally treat for chloramines, chlorine and well water. The kit includes the upgraded GE 1 micron Purtrex Depth Sediment Filter, a new 1 Micron BRS Universal Carbon Block and a BRS Color Changing DI Refill. This kit can be used with NEW 4 Stage BRS RO/DI systems as well as legacy systems and all major competitor 4 stage RO/DI systems that use standard 10” filters.

Purtrex Sediment Pre-Filter
Purtrex Depth Sediment Filters are an exceptional value for general applications where long life, high purity and low change-out frequency are required. Produced through GE Osmonics patented melt blown micro fiber technology, Purtrex is a 100% pure polypropylene depth filter with exceptional dirt-holding capacity. Purtrex true-graded density filter matrix (lower density at the surface of the filter with progressively higher density toward the center) captures particles throughout the entire filter depth. This translates to longer life and fewer change-outs than existing string-wound or resin-bonded filters. BRS Color Changing DI Resin is packaged in foil-lined 4mm Mylar bags AND vacuum sealed to preserve maximum useable life.
BRS Universal Carbon Blocks are manufactured using high performance catalytic active carbon combined with a new binder system technology which maximizes the availability of the critical catalytic sites. The combination of advanced carbon technology, increased volume of carbon contained in each filter and proprietary manufacturing processes delivers exceptionally high chloramine, chlorine, VOC and general chemical performance.

Great packaging By Sunreefer on 1/8/2019Sunreefer would recommend this product to a friendWas like an iPhone box, but more focused on making sure the canister would not crack. Awesome packaging - enough cushion to make sure it comes secure.
Outstanding By Salty Dog on 9/18/2018Salty Dog would recommend this product to a friendBeen using these replacement kits for years. Always produces crystal pure RO/DI reef water that i would argue is of higher quality than that purchased at a LFS!
Love these replacement kits!! By Jay on 8/4/2018Jay would recommend this product to a friendLove these replacement kits!! Makes reordering a cinch and replacement is easy peasy. I started ordering two of these kits at a time so I have extra on hand just in case.
Great system! By Christopher on 7/30/2018Christopher would recommend this product to a friendFast shipping and easy install. Great product, plan on ordering another kit to have on deck! Made about 150 gallons and carbon is about half used.
Awesome kit By Rob on 7/30/2018Rob would recommend this product to a friendEasy to replace filters and knowing you have all that you need is big plus.
Easy change By Jerry on 5/16/2018Jerry would recommend this product to a friendI noticed 1 TDS and the unit was getting some age so I decided to get the replacement . The change over went easy and fast no issues . Thanks BRS

Must have for your RODI By Andy on 11/26/2017Andy would recommend this product to a friendSuper easy install makes trips to the LFS for water Unnecessary. BRS has great units at reasonable prices and these replacement filters are super easy to install. A must have
Great kit! By WVReefer on 10/26/2017WVReefer would recommend this product to a friendThis a great kit...... I don’t have to worry about forgetting anything.
Simple & Trustworthy By Xxero on 10/20/2017Xxero would recommend this product to a friendI love the system and the replacement filter kits. All of the system components are quality built, and the filter kits keep things very simple. It's a trustworthy system from a reputable company. Win win!
Will these replacements fit RO Buddie systems?
These are standard 10" x 2.5" cartridges and certainly should work for most systems as long as the measurements line up. Feel free to let us know if you have any further questions!
I can't find my filter specs, will this work with the Coralife Pure-Flo II (76002)?
Most Ro units are a fairly standard size, this kit should fit in your canisters no problem. Feel free to let us know if you have any further questions!
About how often do you need to change the filters? I assume it would be dependent on the aquarium but I'm looking to purchase a couple replacements for the year for my classroom.
The actual time will vary on water quality, PSI and other factors. Typically the Sediment, Carbon block and DI resin will last around 6 months (the DI can often last less) and the RO membrane will last around 2 years. Feel free to let us know if you have any further questions!
Hey I have the four stage system. Just replaced all 4 filters..now I have a decent drip/leak coming from where sediment filter feeds/attaches to carbon compartment. I tried every wrench I can find but nothing will fit between the two canister to allow me to tighten it.just wondering how I go about fixing it..or where and what size replacement part to buy. Thanks for the help!
I have an R/O system I haven't used in years. I'm looking at your 4 stage replacement kit. My unit has 3 canisters and a white horizontal cylinder on top. Does the top horizontal piece also need replaced and what does it do?
If the unit has been stored all filters will need to be replaced. the 4 stage kit will be perfect! The final filter is the RO membrane which is the main component of filtration. I have included a link to the standard 75 GPD (Gallon per Day) membrane below.
Hi I have the 6 stage and it is hooked up to a well and the 2 resin & sediment have turned the iron color from the well water..do I need to replace them? If so can I use these..it's a 6 stage from you BRS.. :) thank you!
Have a great day!
When would you recommend this 1 micron set vs the 5 micron filter set? And/or is there any value using a 5 micron sediment filter followed by the 1 micron carbon block filter?
We would recommend the 1 micron package to someone who might live in an area with a lot of sediment in the water or perhaps a well.
