Ideally the membrane will last around 2 years. You will be able to see with a TDS meter on the IN section. The ro should reduce around 99% (with a single membrane) and bring your TDS on the In to around 0-10. If on the single membrane it is higher than 10 after running the unit you will want to consider a replacement. With the water saver version dual membrane the IN TDS will be a little bit higher closer to 5-15 TDS. Feel free to let us know if you have any further questions!
Overall they will function on the same process of TFC however certain membrane which are High Silica can last longer due to the negative effect of silica. The difference between the membrane is not that one will remove more or less rather the life span of the membrane for a specific application. Feel free to let us know if you have any further questions!
A new membrane can be stored for quite a bit of time. The manufacturer puts a preservative on the surface of the membrane which can keep good for quite some time (2+ years). That is they recommend discarding any water produced for the first hour or two when it is first installed. Storage for the membrane should be kept in a cool dry place with a steady temperature.
We have found using the system after Water Softener will improve the life of the unit and membrane. This will not cause the unit to clog any faster than normal. Feel free to let us know if you have any further questions!
Membranes are a standard size so they will fit in any unit. Just make sure that if you change the speed of the membrane you also change the size of your flow restrictor to match.
The RO membrane will remove around 97-90% of the TDS for a good range after flushing this should be typically between 000-010 however it can be higher with poor source water quality. Feel free to let us know if you have any further questions!
Most membranes will be a universal physical size and work in all units. You will need to make sure the GPD rating is the same. If they are not the same you will need to change the flow restrictor on the waste water line to a 75 GPD flow restrictor. Feel free to let us know if you have any further questions!
These membranes are recommended for 50-75 PSI the maximum mount we typically see during flushing is 80 with no negative effect. Feel free to let us know if you have any further questions!
The membranes last quite a long time, typically 3-5 years though if you treat them well (vigilant on changing your pre-filters on time, etc) they can last even longer.
That sounds pretty typical. It is higher at first because of tds creep and will lower as it runs. Non-exhausted DI resin should give you 0 TDS coming out. The membrane itself will typically last 3-5 years, sometimes even much longer. DI resin doesn't really have a "normal" as it is completely dependent on your source water. Monitor the TDS and when it begins to go above 0 then it is time to change the resin. We use a color changing DI resin so this should also coincide with the resin turning from a dark blue/black color to a gold/yellow color.
The unit can handle up to 80psi without issue and it does perform better at higher water pressure. I would go ahead and run it at the 80psi, there isn't any reason not to and performance will only go up.
If you change the size of the membrane without changing the flow restrictor to the proper size your unit will have the incorrect amount of waste water. It will either have too little water which would damage the membrane or too much water, which is just a waste of water (and could decrease pressure). The housings for the membranes themselves are universal. The membrane is what changes the output, though there are some other factors such as water pressure and temperature that do as well.
Compatible with all RO systems
FILMTEC reverse osmosis membrane elements for home drinking water are the industry's most reliable. Advanced membrane technology and automated fabrication allow these elements to deliver consistent performance that equipment suppliers, water treatment dealers, and residential customers can rely on. FILMTEC elements are shipped dry for convenient handling and long shelf-life. These elements are NSF/ANSI Standard 58 listed. Equipment suppliers can take advantage of FilmTec's Standard 58 listing and participation in the NSF Data Transfer Protocol to reduce costs for reduction claims for their systems.
- Rated at 50 psi
- Will purify about 20% more water than competitive elements rated at 60 psi

Effective membrane By Brian on 4/22/2017Brian would recommend this product to a friendThis is a great membrane. It does what it's supposed to do, and my TDS reader shows an improvement after replacing my old membrane. I'm down to 0 on the reader now with 100+ on the input end.
Lasted a long time By offgridman on 4/18/2017offgridman would recommend this product to a friendMy first membranes lasted three years. We use lots and lots of water. and have good through put and consistent water quality. We use electronic monitoring and got three years with our last set.
Faster Fill By Todd A. on 4/4/2017Todd A. would recommend this product to a friendGlad I made the decision to upgrade my system from a 50GPD Pentair membrane. Produces water the same ppm but fills the take so much faster.
A great product By Carmen on 2/16/2017Carmen would recommend this product to a friendI have a lot of confidence in BRS products, including this one. Great value, also.
Quality Filter By Jono on 1/21/2017Jono would recommend this product to a friendLasts twice as long as other cheaper RO membranes on the market. High quality and worth the money.
Performs as intended By Anibal on 12/16/2016Anibal would recommend this product to a friendDelivers high quality water at a great price!
Replace yearly By Badabing on 12/10/2016Badabing would recommend this product to a friendEasy to replace once a year, on Black Friday sales, not sure if they need to be but not that expensive for a years worth of water, normally my di resin turns completely brown and I change everything, why take a change on ur investment of fish and corals
Doing its Job By Randy on 11/9/2016Randy would recommend this product to a friendI purchased this to replace my old 100gpd and decided to do the 150gpd upgrade kit. I also added the Dual DI Canister and boy am I satisfied. I'm producing 240gpd and couldn't ask for anything more. I love it and wish I would have made the switch earlier.
Good quality and does the job By Trailjammer on 10/12/2016Trailjammer would recommend this product to a friendEasy to install. The original in the BRS Stage 4 kit has lasted for years. So we will see how long this one lasts.
Performs well By Christopher on 9/8/2016Christopher would recommend this product to a friendDrops supply water from approximately 150ppm to 3ppm for a solid 18 months. Got 2 years from the same membrane that came with the BRS RO/DI kit but only 18 months from the last 2 replacements. No change in supply water quality and I use the membrane flush kit regularly.
Don't use with Spectrapure MaxCap 90 By John on 8/29/2016John wouldn't recommend this product to a friendTried this with my Spectrapure MaxCap 90. Was getting about 30 GPD. Tried different restrictors, including a ball valve to adjust flow to any level. The most I could get was about 75ml per minute which is 28.5G in 24 hours. BRS tech advice was to try their 550ml restrictor barrel but no guarantees. Not sure how it could get from 30 gpd to 75 gpd. If you try and it produces 75 gpd let me know. It could have been a bad membrane but the tech didn't think so. 2 stars because maybe it actually produces 75 gpd with the BRS RODI kit. It just doesn't do it with the Spectrapure.
Easy to change By MaLi on 8/14/2016MaLi wouldn't recommend this product to a friendI changed my membrane for the first time last night, it only took a few minutes. The BRS guide was extremely helpful and made changing it out even easier.
