Before getting a RO system, I tried some quick filter and didn't feel any difference. When searching for a RO system, I was put off by most systems either for their bulkiness or extra maintenance required, until I found this system at Amazon. I am glad for my choice of iSpring. It was easy to install. Other than change filters about every half year, it worked maintenance free for me over one year now. And it only takes a manageable space. RO system did make the difference for my coffee machine and tea kettle. They don't have any visible deposit anymore, and I drink >4 cups of coffee or tea every day. One extra good thing about iSpring is that they have real custom service. I had some issues changing filter and the only thing I need to do is calling the number well printed on the filter itself. A guy called Nick answered the call. And in a few minutes, case solved.
