    Double the output of standard r.O. Systems

    NU Aqua R.O. systems give you 100 gallons of water every day.

    That's double the output of most systems with purer results.

    Purity and longevity

    NU Aqua filters have 30% more surface area over the competition.

    That means purer water and a longer life out of each filter.

    Other R.O. systems require more frequent filter changes. Which means more money on upkeep...

    I replaced an old system with NU Aqua. Thing is light years ahead. The tank is filling up twice as fast as my old iSpring system. And this thing comes with a PPM meter so I can conveniently check the water quality. I went from 250ppm to an incredible 15PPM! Not sure what is in that water but nice it’s gone. Now my water tastes fantastic.

    My wife and I are thrilled with the quality of the water - and even more so after reading an article online about the poor quality of bottled water in America. You'll be blown away at how much better the RO filtered water is. The taste and clarity of the water is exceptional....it has improved the taste of coffee and tea as well!

    Awesome, clean water- love it! I can totally tell the difference from tap water. It's crystal clear and taste so much better.

    Don’t think I will be able to go back to tapwater ever again after having this system.

    This is my thirdwater filter system, and the NU Aqua system is by far the best that I have owned. No need to worry about boiling water any more! It is the best tasting water. In fact there is no bad taste at all, that is the way it should be. I couldn't be more satisfied. Great price, Great product. I would highly recommend NU Aqua RO systems.

    Love my water now

    I knew I needed to do something with my tap water, it is clean but I could still taste the chlorine. This system is amazing, fits in the back after the cupboard under the kitchen sink like a glove. It was easy to install and get up and running, though I haven't had to change the filters yet. Thanks for your product.

    It’s Great!

    Well for me there’s not much to like when you find the thing you’ve been searching for it’s kinda hard find something wrong right away. So for now this review will stand, for now. So this unit already comes pretty much put together. For me the instructions were simple you just attach the proper colored hose to the connector as instructed in the instructions. Before I started connecting the hoses I checked double and triple checked my connectors. After my setup and flush the water taste like water we use to get from a stream in Alabama where I grew up! It’s light and clean no chemicals or additives for taste just clean delicious water! The unit is quiet and very well built in my opinion. As for the functionality it fit right under my kitchen sink perfectly. And it’s very easy to use! If you want pressure you have to get the pump version I think but the water pressure is fine for me since it’s for cooking and consuming more water into our diets. All in all we love it! It goes well want kitchen decor and it’s so easy to use just like your regular faucet!
