We have had the I-Spring 6-Stage RO for 1 year and we absolutely love it. We would never go back to non-RO water. We use it for drinking, cooking, canning, coffee. We even give the dog RO water 🙂 I recently hooked it up to our fridge so we can get RO ice cubes. Our old ice cubes used to stick to each other all the time even when they were freshly made. As soon as we switched to RO, the ice cubes don’t stick and are noticeably better – who would have thought!

Good product.

Two sets of cartridges come in the package. That was not clear in the product description; however it was a pleasant surprise when they arrived. Suggest lining all the parts up and keeping which part goes where as you start replacing them — it was a bit confusing, especially because the name of at least one of the cartridges had changed since I originally purchased them.

Great product, great company, great service. Iv been using an iSpring 6-stage RO system for two years, and I cant imagine how I ever got on without it. The filter system turns my tap water into a great tasting source of hydration, not to mention the peace of mind I get, knowing whats NOT in my water, after it has been through RO.

Not much to say, other than I found out that the other filters wore out right about on time, so I needed a new set this year after purchasing the system last year. Overall, I’ve found the system to be very good at a very good price. My TDS (total dissolved solids) meter indicated that yes, the filters are removing almost everything from the water, and the alkaline mineral infuser adds minerals back in for your health and for taste.

excellent filters and services

I regularly measure the quality of drinking water at my home and I have been very impressed with the performance of iSpring RO system. Just purchased this filter bundle because it’s about time for filter replacements. I had some issues with the Alkaline filters. After some email exchange I become even more impressed with iSpring’s prompt service. The company truly values and really takes care of their customers.

With Houston water, our original filter pack lasted 5 months before we noticed a change in taste.
