## Questions & Answers

**Q: What is the difference between the mc7 and mc1?  i have an rcc7 unit that i purchased 2 years ago**
A: Hi Gregory, the the difference between the two membranes is the gallons per day produced; the MC1 will fill the ro storage tank a just a couple minutes quicker than the MC7. 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. Thanks, iSpring Water Systems
