  1. Easy to install & service!

    Easy to install & service!

  2. Worth it

    Posted by Chandler AZ on 23rd Apr 2015

    This is the second unit we bought. We had one in our home, and installed one in the rental. The ease of installation, and then easy of changing the filters is worth it. I think swapping the cartridges saves soo much time. If I had a 3rd house, I would install the same.

  3. Great upgrade

    Posted by Unknown on 22nd Feb 2015

    I upgraded from the older 5 stage RO system so I wouldn't have to call the plumber every time I changed the filters. These new ones just pop in and out so easily. I'm pleased with the system and really like the new faucet with the LED light. Happy I upgraded!

  4. Best water ever

    Posted by Unknown on 15th Oct 2014

    We always order one of this each time we purchase a new home. I just wish you could choose which faucet it comes with so I would not need to order the one that matches my faucets better.

  5. Premier 531417 RO-Pure Reverse Osmosis System Plus

    Posted by Unknown on 30th Mar 2014

    Found product to be very user friendly as far as installation went. Should be easy to replace filters when needed.

  6. Love it!

    Posted by Unknown on 2nd Jan 2014

    This is second one of these I've installed. First one for my daughter, an MD, and now for me to replace an earlier model that was not as easy to change filters. The new install was easier than removing the old one. They have really improved their designs in terms of ease of installation and use. And it works great. I have a TDS tester and get around 135 from straight tap and only 5-10 from RO right after installation and initial flushing.

  7. Easy install / delicious water!

    Posted by Bob on 23rd Sep 2013

    I'm somewhat handy and it only took me about an hour to install the system. The water is absolutely delicious!

    We did add in a ph balance filter right before the faucet to re-mineralize the water. It is absolutely delicious. No more chlorine smell. Just smooth and tasty water.

    We did run into a minor issue during install which turned out to be that the bladder in the tank was not inflated. I simply drained the tank, inflated to spec, and hooked the tank back up and it worked perfectly.

  8. Easy to service and it works well

    Posted by G Plunkett on 28th Aug 2013

    This is my second RO Pure system. I have never had any problems with either, and the water was still coming out pure after more than three years. One important point is to be sure to change the filters every six months, and it is so easy to do. With other filters it took me half a day to replace filters but now I can do it in a few minutes. I did have trouble with the adapt-a-valve so I replaced it with a T and water valve and everything works great.
