Great product(RCC7P-AK), great cusotmer service (special thanks to Nick) for help on fixing my problem. The system runs flaw less once setup is done appropriately. Dont have to do multiple follow ups like other company cusotmer care services.

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

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.

Usually, people don't think about water filters often, but filtering elements need to be replaced regularly. In the case of a reverse osmosis membrane, its lifespan is 2 to 3 years depending on usage intensity. Personally, I believe it’s better not to wait until the membrane is completely worn out and to replace the filtering element when you can visually assess that the water quality has declined, doing it a bit in advance. Most importantly, you need to clarify which membrane is necessary for your filter (if you're not sure, it's better to ask your cleaning lady). I have an iSpring RCC 5 filter, and the membrane fit perfectly. Based on how much the taste of the water improved after the replacement, it was definitely time to change the previous one! The price is also reasonable. Overall, if your filter needs a replacement, you can confidently go for it.

Good product

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.

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.
