Review: Works with APEC RO systems - Worked fine with my APEC RO system. This membrane is way less expensive than the one APEC sells.
Review: Excellent Membrane - 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.

## Questions & Answers

**Q: Why did my tds go from 0 to 2. I flushed for 2 hours tds started at 1 then went to 2. With my old 3 year old filter I was at 0 tds**
A: There might be different reasons causing this problem. It is better to empty the tank 2-3 times after changing filters. You may also replace other filters and sanitize the system if you need to. You may check online about how to sanitize your water filter system. Please remove all the filters from the system before you start to sanitation procedure. If these don’t solve the problem, you may contact with Amazon customer service to return the item.

**Q: Is this Filmtec membrane made by Dow or Dupont?**
A: DuPont merged with FilmTec company and became a part of Dow FilmTec. Eventually, they will produce all the Residential FilmTec Membranes, and we started selling them too.

**Q: is this made in usa? I see another listing with the same numbers on it that says "residential" and it says imported.. Its Dow and numbers are the same**
A: i be leave if it says imported , its still an American product that's just assembled in another country. Dont worry they work real good ,Total TDS 000.

**Q: does this fit the 10"x2.5" canisters**
A: The housing size for this membrane is approximately 12.5” x 2.5”. If your housing size is 10 inch, this membrane can’t fit in because the membrane itself measures as 11-3/4” x 1-3/4”. However, if you are replacing the same brand (Dow Filmtec) undersink RO membrane, there won’t be a problem. You may also check with your RO manufacturer.
