Either membrane is compatible with the RCC7. **Q: When should this be changed?** A: It should last 2 to 3 years. However, I use a TDS meter to monitor pollutant levels. The water in Alpine, TX is not very good according to the TDS readings. I change my RO membrane twice a year and the other filters about every 3 months. I am probably a bit of a fanatic though. Check out 123filter.com for filter information. I stopped buying from Amazon because I got a better price and their customer service is awesome. Amazon customer service is excellent but 123filter is in the RO business. Very helpful for problem solving. **Q: Are there any specific instructions? Do you have to run water through it awhile before using?** A: There will be specific instructions but in any case it is always a good idea to flush the system few a few minutes before using. The important thing is to keep the membrane wet. Tech support at isptings is awesome too. **Q: Will this fit ispring rcc7ak?** A: Hi Elizabeth, Thank you for your question. Yes, this is the membrane filter used in the system rcc7ak.
