Over the years Ive made a number of attempts to clean up my drinking water. Quite a few filter pitchers came and went. The under-sink carbon filters were a step up. But that only lasted until I started to read more and more about what was actually in my water. My city water utility kept sending reports about how wonderful their water was and that they met or exceeded all federal guidelines. Well, that did it, and my paranoia started to ratchet upward so I acquired an older, vendor installed reverse osmosis system that I was given by a friend. When I took it apart and cleaned out all the gunk I discovered that the replacement filters were going to cost a small fortune. After doing quite a bit of research I easily came to the conclusion that the ISpring system offered the best combination of high quality, reverse osmosis filtration and price. Since I was already sensitive to the issue of filter replacement I was pleased to discover that keeping the unit functioning properly was going to be less expensive than most of the competitors--sort of like the toner issue with printers. The installation went smoothly and I was delighted with the fawcet that came with the unit. It was beautiful and high qualitysort of like getting a bonus you hadnt expected. Ive had the unit for almost two years and couldnt be happier.

Our municipal water supply has a very high water hardness (142 mg per litre) and the smell of chlorine is quite evident when you draw it from the tap.Our home has a whole house sediment filter on the supply line . It is changed every six mouths. It has had some interesting contaminants. I have been buying bottled water for years now as our main drinking source. The Rog400 unit I bought has replaced a Rain Fresh 2 Stage water filter located at the kitchen sink. The water quality is much better now and it is a pleasure to drink from.

I installed this unit today. I had to remove my old R.O System to install the new Unit. Am very happy with the unit and looking forward to using it. I have had some serious health problems that caused the long delay in the installation.

Easy install. Just follow the instructions. Works great and the water tastes great. I added a tee and ran 25ft of waterline to the refrigerator/ice maker. Now we have awesome water and ice.

I hate to drink water, especially tap water. People think I'm crazy when I tell them how nasty it tastes to me. I've lugged bottles of water home from the store for years but nobody stays young forever and I must admit that it is getting more and more difficult. Plus, my conscience was constantly nagging at me about all the plastic I was throwing away. My daughter had a reverse osmosis system installed, and after tasting her water, I decided to follow her lead. I did pretty extensive research on systems that would fit my needs and the ROG400 hit the exact sweet spot between cost and quality. Plus, it comes with a brushed nickel faucet to match my kitchen. When it arrived, I called my friend Dave the Plumber to install it for me. Dave knows plumbing, but has not installed many of these systems. Instructions were clear and everything he needed was included. I didnt want to give up space under my kitchen sink, so he installed it in in my basement directly under the sink. The most difficult part of the installation was drilling a hole in my cultured quartz counter top. I was a little concerned that the water pressure from the tap would be slow since the water has to travel all the way from the basement, but I was pleasantly surprised to find the flow is totally adequate. I couldn't be happier with this system. I have a water tester and it consistently shows a dissolved solids reading of around 4, which is the same as the filtered water I bought from the store. If youre looking for a reverse osmosis system for your kitchen, I highly recommend this one!

The installing technician was explained how the system worked and installed it replacing a defective RO system. After the initial cycle the system has worked perfectly. It has an outstanding water flow without a water storage tank.

Great product! Had to install post filter to remove cloudiness. Water tastes great and saved lots of room on not having a tank.
