FilmTec, BW60-1812-75 75 gpd TFC Membrane for Undersink Reverse Osmosis (RO) System (Replaces Model TW30-1812-75)

Worked fine with my APEC RO system. This membrane is way less expensive than the one APEC sells.

satisfied.

RO company wanted over $135.00 for a new RO assembly. This one fit in the housing and works great. Saving a Benjamin on this replacement is awesome. Note, I did verify the flow restrictor and check valve were good.

I use this in my APEC RO-PH90. This is a fabulous price, and I am grateful because my last membrane went after 2 years instead of the reported 5 year life. The first membrane I received had holes in the plastic packaging (directions say not even to touch it during installation so I figured holes in packaging probably compromised the membrane) so they sent another and I returned the initial membrane. It fit perfectly and the system is back to working properly.

I work in industrial water treatment with ROs that have up to 168 membranes at 8" each. We are very nearly Dupont/Filmtec loyal and for a valid reason. They have the best membranes and their organization is the best at what they do. Very knowledgeable and very much experts in the field. While this little membrane of novelty size is much smaller and less serious, it is still of very heavy high quality. There's is not another membrane on the market that will perform over a long period of time at the level that Filmtec does. This membrane is capable of so much more, but given the environment it's been put in (poor pretreatment and low feed pressure) it still does an excellent job. Definitely recommend.

*I have been using Dow/Filmtec RO Membranes for a decade.* There has not been any changes in the quality of this product during that time. My tap water is 184 TDS post RO filter and 0 TDS after filtration and I've included photos with a TDS meter. I see a lot of negative reviews on a good product and I'll try to clear up some of the misconceptions with my review. First - Dow/Filmtec is known for making one of the best RO membranes in the business hands down. There is only one other more expensive brand I can name that some claim is slightly better but it will produce water even slower which is upsetting many reviewers here. If your goal is to produce the purist R/O water possible which is 0 TDS you can't go wrong with this membrane. I recently ordered a replacement filter after a few years of use and I'm producing water with 0 TDS which is 0 total dissolved solids. I'll now try to clear up the misconceptions. The rejection rate is around 98% which is SLOW and you want SLOW the higher the rejection rate the more efficient the filter is and the more money you'll save and I'm about to explain why. The higher the rejection rate the longer your DI resin filter will last. Water flows through this RO Membrane and into your DI resign which is the finale filter that works the hardest and is the last line of defense against dissolved solids in your water column and if your filter is setup properly will bring your TDS down to 0. You want the rejection rate high so the least amount of solids make it into your DI resign which is the most costly filter to maintain and that processes of rejecting contaminants in the water at a 98% rejection rate causes the water to be made slowly. The Next big misconception is not realizing the filters before your membrane are the biggest factor in how long not only this RO membrane will last but any of them will. R/O membranes have a chlorine tolerance of >0.1 ppm. If any chlorine manages to pass through your carbon filters because their exhausted or low quality and reach the membrane it is instantly ruined and you can throw the membrane in the trash. That is why the pre carbon filters must be kept in working order. I use this membrane to make water for my reef systems and I have a large reservoir to hold the water. The output is as stated around 75 gallons over a 24 hour period. If you live an area with extremely high TDS the process will be even slower because your filters need to work harder and also won't last as long. Keep in mind some cities have been adding chloramine to tap water for a secondary disinfectant which is ammonia based without residents knowing. You will need a different carbon filter in your water filtration system to remove it. Check with your city if you can't seem to get your water filtering correctly and ask. *If you did find this review helpful please leave a helpful up vote.

The filter fits my Apec RO system. Not sure about its quality and would need time to check.

I received exactly what I ordered from Water Anywhere , a genuine Dow FilmTec, BW60-1812-75 75 GPD TFC Membrane. Installed to my 5 stage RO system the new membrane plus two carbon block pre-filters and one post carbon filter from Watts Premier WP500024 Standard Annual Water Filter Replacement Kit and a 1 micron, micronfiltercartridges string wound sediment filter instead of the 5 micron sediment filter included in the Watts kit. The 1 micron filter protects the carbon block filters from clogging much better than a 5 micron. After a 2-3 week break-in period could not detect any total dissolved solids using analog meter, Myron L Company RO Meter Model RO-1. Chlorine and chloramines damage membranes. Use a pool chlorine test kit to test the RO system waste water to make sure it is chlorine free. Don't risk ruining a new membrane because of low quality or counterfeit carbon block filters. Finding quality filters is a real challenge and is of utmost importance.
