I've been using this filteration system for many years and have been very satisfied with the quality. Recently, one of the housings cracked which led to water leak and Sean helped me to replace the entire unit for free. I've installed the new unit and it's working great as before. Thank you Sean and iSpringFilter team!

I've had the unit for 8 months, and it has been superb. The water tastes absolutely fantastic. I had a non-system-related leak, which triggered the stop water mechanism. I called in and got Sean. He was great, explaining how the mechanism worked and how to correct it. He then offered to send me a replacement mechanism free of charge, as I damaged mine during the repair.

I've had this system for nearly 3 years and my family and I thoroughly enjoy it. The flavor improvement is really noticable and I appreaciate all the extra filtration that doesn't happen at our local municipal water system. I found it easy to install using the quick connect connectors and I haven't had any leaks. Maintenance consist of just changing filters as directed. I recently had my first issue where water would no longer flow properly from the faucet. Sean helped me troubleshoot and sent me parts until we fixed the issue. Thank you Sean!

I bought my iSpring Reverse Osmosis Filtration System, RCC7, in September of 2023. I am completely satisfied with the system. We have an under-sink version, which is where most of the water we drink is dispensed. Because we wanted the best water we could drink, we also connected our refrigerator water and refrigerator ice-maker to the filtration system. We believe we have the best system for providing fresh, great-tasting, clean water. In September 2024, I replaced all filters except the Reverse Osmosis filter. This September 2025, I was unsure about whether I needed to replace the Reverse Osmosis filter. I called support, and Sean explained what I needed to do. Thank you, Sean and iSpring, for having excellent support and a filtration system that we consider 5 stars. Richard Pollak
