iSpring Greatwell NSF Certified Reverse Osmosis Membrane 75 GPD 11.75” X 1.75”, Replacement Fits Standard Under Sink RO Drinking Water Filtration System, MC7

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!

These filters do a great job. I also have a whole house filtration by iSpring so the first filter is always clean but the other filters seem to do a great job. The drinking water and ice from refrigerator has great tasting water and ice. Filter changes are fairly easy to perform. Take a photo of the hoses prior to change to make things easier when putting back in. Two years of filters is great to have on hand. We get our water from a big reservoir in SE Texas, so think about the chemicals, urine from animals and even the dinosaurs that are always present in water. Those things never go away completely.

The product was easy to instal. The price was acceptable and competitive.

Works Great, Awesome for the time they last and price is good! They last a long time, tested quality with water testing strips and they definitely make a huge difference. Will buy again!

I ordered and received this item several months ago. My filters were due to be changed this month so when I opened the box, I realized that the FT-15 filters were missing. I called, and spoke with Michele from iSpring customer support! She was kind and very courteous. She also promised me to ship replacement filters out right away! I went away for the weekend, and to my surprise when I returned on Monday morning, the filters were waiting for me in my mailbox. iSpring is to be commended! Customer service like this, is unheard of in this day and age! I would like to add that this was my first time changing these filters and the tank, and I must confess that it was a breeze. The video provided on the iSpring YouTube site made it all seamless. The water pressure was good once the tank was changed and the color and quality of the water was excellent once I followed the procedure. Great product!

Pleasntly surprised to have received 2 refills. Not difficult to install and makes our water taste great

Sean at iSpring was amazing. He helped me find the user manual and some YouTube videos to assist me with regular maintenance. So far, this water system has been perfect for my house.
