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 have used ispring reverse osmosis for at least 13 years. I love their systems. They are so easy to change out filters and the company has been amazing to work with. I’ve had a few small issues and they’ve sent me free filters and free water tank. They’re very patient and helpful to work with Sean and Nick are two of the people that I’ve had conversations with and helped me troubleshoot some problems. I may actually pick up the phone when you call. They’ve been a great company to work with. I have also bought systems for my mom‘s house and my daughter‘s house and they’ve been wonderful. Can’t say enough good about this company.

The iSpring 6 Stage RO Water System is an exceptional product that truly delivers on its promises. This water system is designed to provide you with clean, fresh-tasting water that is free of contaminants, and it does so with ease. One great feature of this water system is its alkaline remineralization filter. This unique filter adds back beneficial minerals like calcium and magnesium to your water, which not only helps to balance its pH level but also improves its taste and overall quality. The installation process for the iSpring RCC7AK was also incredibly straightforward. You don't need any special tools or plumbing experience to get it up and running, and the included instructions are clear and easy to follow. Once installed, the system is also low maintenance, with only a few filters that need to be replaced every six to twelve months. The company also has some of the best Customer Support I've encountered for any product. Sean at iSpring truly cares and went over the top in helping solve an issue I encountered after a few years of use.

After purchasing and personally installing three iSpring 6-stage reverse osmosis systems, I can confidently say that iSpring sells excellent, well-designed water filtration systems and stands behind them with equally impressive customer support. Whenever I have had a question or needed assistance, I have been able to speak directly with knowledgeable professionals at their Alpharetta, Georgia headquarters. People like Nick clearly know these systems inside and out and have always been patient, helpful, and genuinely pleasant to work with, regardless of how simple or complicated my question may have been. Having installed three of their systems myself, I have had plenty of opportunity to evaluate both the products and the company behind them. Based on my repeated experience with iSpring, I would not hesitate to recommend their RO systems to anyone looking for a high-quality water filtration system backed by excellent U.S.-based technical support.

Don't waste your money on cheap imitations! I have heavy amounts of minerals in my water. Not quite hard, but way up there. I bought the reverse osmosis system to provide water for my whole house ultrasonic humidifier. It worked great for 2 years, then the water output decreased to the point it was obviously time to change the membrane. I got one of the cheap knock-offs & it was an unmitigated disaster! I replaced the aftermarket membrane with the OEM one & everything was back to normal.

I've had my 5 stage iSprings system for about 5 years. It gives me better than bottled water quality but since I fill a stainless steel container, it avoids about 10-12 plastic bottles every day (YES, I drink a lot of water). It's very important to change out the filters periodically. I was very good and did it at 1 year, then it slipped to maybe 18 months. I was on my 4th filter change-out. The RO cartridge and other early stage filters have always been easy and never a problem. However, for this event, I could not get the 5th stage final filter to stop dripping. I went on the Amazon order page and selected "contact seller". A nice person named Sean reached out to me. Buying things unseen always presents a risk but not with iSprings. Sean informed me of his immediate actions to send me replacement parts but also took the rare step of conveying a feeling that no matter what happened from this point forward, he was taking ownership of my success in getting the filter back on- line. The replacement parts arrived and also leaked but Sean sent a third set of failed parts and a bit of hose. That did the trick. I think possibly my old tubing had gotten brittle such that it was preventing a good seal with the o-rings. Maybe I hadn't pushed it far enough into the fitting or maybe it kinked. for some reason it wasn't making a good seal. Each time I pulled out a failed connection, I could feel new imperfections on the outside of the tubing. I cut it off each time between repeat attempts. I didn't not pull out the new successful tubing to see if it has this same phenomenon. The only downside of this or any other under-sink system is that is takes up space and that involved some negotiation with my wife so as to not have supplies piled up around the filter unit. Anyway- if you are deliberating an under- sink filtration system, I highly recommend the iSprings system. It has everything a person needs to drink cool clear water. It is easy to maintain. If you have some problem, iSprings will jump in the foxhole with you to fight whatever you may be battling.

I purchased my current iSpring RCC7, NSF Certified, High Capacity Under Sink 5-Stage Reverse Osmosis Drinking Filtration System about 5 years ago. The water in my area is very hard and not consumable directly out of the tap. iSpring makes every glass taste even better than bottled water. I chose 4 stars instead of 5 because my water is so hard I have to replace membranes more frequently than I anticipated. I’m pleased with the way the system works. I love the membranes are available on Amazon with quick shipping. I had a question recently and Sean from iSpring was very helpful. Sean, thank you for your expertise. If you have questions reach out to iSpring for great support from reps like Sean!

I've had my iSpring 6-Stage Alkaline RO Filter for 3 years and absolutely LOVE it. After 3 years of use, you need to change the RO membrane filter. I wanted to make sure I ordered the right one, so I called their customer support and spoke with Don. No waiting. No phone menu of options to choose from. He just answered my call immediately and told me which filter to order, gave me tips on how to change it, and offered to send additional fittings in case I needed them. I wasn't concerned because I've always had my plumber change my filters, and it has always been easy. But after reading some of the more recent online reviews, I thought my plumber might have problems. So I called iSpring a second time and spoke with Nick -- again no wading through a phone menu before talking to a live person. Nick gave me more information and said they could expedite the additional fittings in case I needed them. This time I said yes. As it turned out, the filter change went as smoothly as the previous ones, but I appreciated the extra fittings and extra support from iSpring staff. And I really appreciate how support is such a quick phone call away. Thanks much, Don and Nick. I'm enjoying my clean water and the money I save from not buying bottled.

iSpring provides a quality product, but more than that is their customer service. I had a problem (after 10 years) and Larry at iSpring helped me to work it out. Pointing out what I might need (hadn't changed filters in 10 years) and gave step by step instructions on what I needed to do. System is up and working fine! Ken

nice

Input TDS - 1700 Output TDS - 125 (using it for last one month). Unbelievable!! Only thing to be seen is if it lasts over 10 months. If it does then I think it is quite great.

Excelente producto!! Funciona muy bien!

Muy buena membrana, me dura perfectamente 2 años sin problemas.

très bien RAS
