Unmatched 2:1 Water Production Efficiency

The NU Aqua 600GPD Tankless Reverse Osmosis system is a powerful and efficient water purifier that produces great-tasting water without wasting too much water. It has a 2:1 pure-to-waste water ratio, which means that for every 2 gallons of pure water, it produces, it only wastes 1 gallon of water. This makes it one of the most efficient RO systems on the market.

Cleanest Drinking Water Possible

Our RO system removes 99% of contaminants for clean drinking water. Its manufacturing process with ultra-fine carbon mist and high-pressure injection ensures high absorption, long filter lifespan, and efficient removal of contaminants like lead, fluoride, sodium, viruses, bacteria, and more. Enjoy pure and clean water.

Superior Quality

The NU Aqua Platinum Series has gone through rigorous testing for leaks, pressure, long cycles, and water quality - this allowed NU Aqua to provide an industry-leading warranty of 1 year.

Easy to hook up and is working great.

Christy Eichelberger
Love it! ❤️

It took me awhile to get it installed, but so far so good. I love having RO water. I admit the blue light is a bit over the top for someone who is used to basic RO units, but I am sure that will be a good thing down the road at filter changing time. I bought it for the tankless feature and wasting less water!!

Great tasting water!

We had an RO filter before, but this one is better. The water tastes great and it saves space under the sink. It's simple to use and creates less mess. I give this 5 stars.
