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.

The nuaqua filter system looks good. Good design and great quality. But the problem for me is that the ph of my water doesn't change

John Kliestik
Fast refill

This is fast refill water filter.It tastes a little bit different because we have extra filter for minerals putting back in water.I think we love it .The only thing I didn’t think when I was buying it that it Needs electric outlet so my installer needed to build in outlet in our cabinet.Works great!

As advertised

Great water, works as reviews state. Haven’t Hooked up the alkaline filter yet, but water tastes good without it IMO. This went into our 5th wheel RV and was easy to install. Came with 98% of what I needed, just had to go to local box store and pick up a special fitting I needed. Nice that you can shut it off with a button when not in use for RV application. Compact design is nice. Filter change is easy. Flow rate is good thanks to integral boost pump. Would recommend this system.

A Very Happy Customer!

For years we have used an on-top-of-the-counter RO unit - attached to the faucet and filling several bottles to use for the week... I could not cook or use the sink for the morning it would take to fill each bottle. Then, all week I would have a huge bottle sitting out to use. I am so, so happy to use this tankless, under the counter unit!! I watched Nu Aqua video instructions (very well done and easy to follow!) and we had it together within an hour. The separate faucet is beside the smaller sink side and leaves the other side open to use all the time. We drank the water after a few minutes of flushing and was the same great RO water we are used to! I could not be happier and give this company ten stars!
