We purchased a 6 Stage Reverse Osmosis water filtration system from I-spring a year ago. Great product and produces quality tasting water. One of the housing generated a crack and Jonathon, with customer service, quickly sent out a replacement part. Very happy with the product and customer service.
Robert was a pleasure to work with when registering the system for the warranty. It was an easy instal, less then 30 minutes, and I instantly fixed the iron issue I was having. I would highly recommend this unit to anyone.
I had absolutely no idea what I was doing while trying to replacing my reverse osmosis system. I managed to get some of it done, but I was stuck with one last thing. I called ISpring and spoke to Jonathan. Wow! Wow what a difference he made for me. He patiently guided me on parts and procedures that I had formerly missed.And here’s the crazy thing: he just rattled off the part number! He KNEW THE PART number! It blew my mind, This was something I was kind of dreading, and he was so relaxed, capable and patient helping me troubleshoot. Give this guy a raise-he’s worth it. If he could help me he can help anyone.

Had a problem registering my RO800 G Tankless RO system, John responded within a few hours and handled for me. My RO800G RO system installation was easy after watching their YouTube clip. My water tastes excellent and I am extremely happy with my product and customer service response. I will bounce questions off John before I make my decision on my whole house system. Very satisfied customer here. Thank you John.
John went above and beyond what we expected. He is a customer service super star. John listened to our concerns and got back to us when he said he would. You don’t get that kind of commitment today.
I got this product about a month ago, and so far, so great! Before buying, I did months of research - clean water is very important to my family, and this one stood out. We're very happy with it so far! One thing worth mentioning: the cooling system seems to run for a long time. It got a bit annoying, so I've stopped using that function for now - I just keep a pitcher of water in the fridge instead. Thank you for inventing this product! Also, Julius was great help activating my warranty. Excellent customer service so far — thank you!
Installed this unit about a month ago. We live out in the country with well water, going through a water softener. I was concerned about the level of sodium from the softer, so purchased and installed this unit. Works great so far. Highly recommend it.
Not only their tankless systems are great but they have high quality customer support. Within a week of installed, my systems' electrical component failed. Jonathan sent me a new tower immediately, and I didn't even have to return the old one. You don't get that kind of service these days anymore. They have my loyalty. Thank you, Jonathan!
I recently got my iSpring water filtration system and reached out to set up the warranty registration. Jonathan assisted me, and he was incredible—super helpful, efficient, and friendly throughout the entire process. It’s rare to find customer service this prompt and hassle-free. Thanks to Jonathan, I’m confident and set up for the long haul!
Bought a new RO setup and had a small issue with the stock UV filter creating an odd water taste. I reached out to support and John was fantastic, sending me a new LED based UV filter right away that should fix the taste issue.
I would like to sincerely thank “ John “ from iSpring Water Systems for the outstanding support he provided in handling my complaint\. His service was extremely professional, responsive, and efficient from start to finish\. He addressed my concerns promptly and ensured everything was resolved quickly\. It’s refreshing to experience such excellent customer service\. Thank you, John, for your dedication and commitment to customer satisfaction\!
I needed clean RO water for my expensive Italian espresso machine. After shopping a bit I settled on the I Spring PH100. I love that it has standard filters available everywhere. The water is very tasty. Hopefully the unit will perform well for years. It seems sturdy, and I like the extra spare parts and connectors that were very helpful in the install. I had a small leak issue. It was just like a drop every three or four hours. John with customer support was quick to send me replacement parts. The installation instructions could be better, but I managed to understand how the system works and where to attach everything.

Jonathan helped me very quickly with my issue. Highly recommend.
John is simply the best! 🌟
Jonathan was so kind to answer the phone at 4:59 on a Friday afternoon. He was kind and patient with me and my many questions. I'm so excited and looking forward to my new water filtration system! Thanks, Jon!
I've had to contact iSpring for an older system a few times over the last few weeks. This is THE customer experience you'd hope for in any company. Thank you, Jonathan, for your assistance in figuring out how to bring my older system up to date.
