- 4 Stage RO/DI Replacement Filter Kit - Bulk Reef Supply
Works with all BRS 4 Stage RO/DI Systems
This kit is designed to treat all primary water sources that are treated with chlorine and wells with low amounts of contaminants. This kit will work with all BRS 4 Stage RO/DI Systems and most other RO/DI units on the market today that use industry standard 10” filters.
- Purtrex 5 Micron Sediment Filter
- BRS 5 Micron VOC/Chlorine Carbon Block
- 1.25 lb. Color Changing DI Resin Refill
The 4 Stage Replacement Filter Kit has been carefully selected to provide the best filtration for chlorine and VOC reduction. The kit includes a 5 Micron Purtrex Sediment Filter that are true graded density filters that will last longer than traditional sediment filters. The BRS Chlorine VOC Carbon Block has been specially formulated for industry leading chlorine and VOC reduction. We also include a single cartridge refill of color changing DI resin in a vacuum packed mylar bag.
Recommended installation for this filter kit:
- Stage one: Purtrex 5 Micron Sediment Filter
- Stage two: BRS Chlorine VOC 5 Micron Carbon Block
- Last stage: DI Resin
BRS Chlorine and VOC Carbon Blocks are manufactured using high-performance carbon combined with a new binder system technology which maximizes the volume of microspores and surface area to improve performance. The combination of advanced carbon technology, increasing volume of carbon contained in each filter, and proprietary manufacturing processes delivers exceptionally high chlorine, VOC, and general chemical performance.
- Chlorine 15,000 @ 1 GPM**
- High chemical adsorption*
- 30% more carbon than standard blocks***
- VOC Reduction
- Exceptionally low-pressure drop
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 microfiber 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 Resin is packaged in foil-lined 4mm Mylar bags and vacuum sealed to maintain maximum storage life and effectiveness.
- Changes color from blue to brown as the media is exhausted.
- 2-year shelf life (unopened)
- Total cation capacity: 1.9 meq/mL min (Na+ form)
- Total anion capacity: 1.25 meg/mL min (cl+ form)
Note: Membranes are not included in standard filter replacement kits. Membranes should be replaced as needed.
*Nominal Micron Rating for all above - 1 micron

Great kit! By John on 5/2/2018John would recommend this product to a friendSimple and easy way in swapping out filters. It's a no brainer!
Works as designed and a great price By Brian on 3/23/2018Brian would recommend this product to a friendProduct does what it is designed to do and comes at a reasonable price. Just make sure you flush your RO membrane good before installing the DI crystals.
Great filters By 75SPS on 3/14/201875SPS would recommend this product to a friendRunning a BRS 150gpd RO/DI unit. Nothing bad to say.
Good Filters By PhilH on 3/7/2018PhilH would recommend this product to a friendI have a 4 RO/DI unit that uses these filters. I use the water for my 2 fish tanks and for drinking water. I change them when I get a 1 tdi reading which is typically every 3 months..
I haven't used it but I'm sure it's fine By Michael on 10/27/2017Michael would recommend this product to a friendI bought the filter replacement kit because it just seemed like a good idea; I'd had the unit for a year or close to it, and the DI canister won't fill up all the way anymore. The output number on the meter is just one, sometimes two, but I thought it would still be a good idea to replace all of the filters and the DI stuff at the same time so I bought the kit. It's VERY inexpensive.
I can't get the filter canisters loose from the RO unit without concern over breaking the unit. They just won't turn. SO, I put the replacement filters back in their packaging and put them in the garage, where they'll likely sit for quite a long time.
No related items recommended for this product.
I have a spectrapure cspdi system will these filters fit as a replacement? Thanks.
Our 10" sediment filters, carbon blocks, and refillable DI cartridges will fit all standard 10" RO canisters. From the looks of it that is what your Spectrapure unit uses so these should work perfectly for you.
