Review: High-Quality Filters That Keep My Water Perfect! - I’ve been using iSpring reverse osmosis systems for years, and this 2-year replacement filter set is a total game-changer. The F19K75 set has everything I need to keep my 6-stage RO system running like new, and the fact that it’s NSF certified gives me extra peace of mind about water safety. Installation was straightforward—even for someone like me who's not exactly a plumber. All the filters are clearly labeled and well-packaged. I especially love the alkaline mineral filter—it really improves the taste of the water and helps balance the pH. It’s crisp, clean, and noticeably better than bottled water. The 19-count set is a great value and lasts the full 2 years as advertised, so I’m not constantly reordering or worrying about when to change them. It’s a small investment for long-lasting, high-quality water right from my tap. Highly recommended for anyone with an iSpring system. You can really taste the difference!
Review: Great RO Filter Kit A+ - I got tired of paying $200 every year for my RO dealer to change filters and every time I asked for what filters they use, they would give me the run around and avoid straight answers, so did my own research and this filter kit is great has everything you need, easy to install and fits perfect, no leakage, water quality and clarity is really good, water taste is good, only issue I had was the activated carbon filter had the push connections and my old one had screw on type connections so I had to buy new connections, but now that it's done it will be easy to replace, Highly Recommend This RO Filter Kit.

## 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
