Review: Great Membrane ! better than 75 GPD - Great membrane! Purchase the 50 and not the 75 GPD. See my story below about 75 GPD. I Purchased the 75GPD membrane as a replacement for the 50 GPD membrane from my original Ispring RO system thinking it would give higher flow. Original system with 50GPD was reading 20 to 40 parts per million (ppm)for my water for about 8 months (good), then went above 50 ppm. The 75 GPD replacement membrane never made it below 70 ppm. I contacted Ispring and they were very nice and sent a replacement 75 gpd membrane, this one did no better than the first 75 GPD membrane. Ispring said that my RO system probably had a crack. After dealing with this bad memebrane I decided to purchase the 50 GPD membrane that came with original system. After I installed it my water was back to 20 to 30 ppm. I recommend that you purchase the 50 GPD not the 75 something is wrong with the 75 GPD construction. Also buy yourself a Total Dissolved solids meter for $15 to make sure your RO is maintaining 0 to 50 ppm.
Review: Clean drinking water and user-friendly system - I've had an iSpring filter system in my house for several years and I am very happy with this product. Not only do I get clean drinking water, but I am happy to know I'm helping the environment too! Recently, I needed to change the filters (and although the process was straightforward), I needed some additional help with parts (yes, I did this myself because you really do not need a plumber) and so I reached out to their customer service. Nick was a great help and helped ship me the correct parts to maintain my system. This is a great way to have fresh, clean water coupled with great customer service too!

### ⭐⭐⭐⭐⭐ Great tasting water
*by J***B on October 17, 2017*

I've been very happy with my iSpring RO system. I change the filters at the recommended intervals and enjoy great tasting chlorine free water at a fraction of the cost of bottled water. Get one of these systems and enjoy!
