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.

Richard Schrader
800 tankless filter

Very easy to install. Enjoy the tankless and the steady stream of water it produces. Good pressure in the line also.

Bruce McPherson
New tankless system

Replaced 10 year old tanked RO system and love the new technology of the tankless system. Easier to install this than taking the old one out.


Everything came in a BIG BOX. Well packaged. Itemized. Instruction booklet clearly specifies installation. The only difficult part in getting your body under the sink! Everything else is quite simple. Although it might take more than an hour to accomplish the tasks, the success is secure. It works perfectly and as advertised. I had replaced my previous EcoWaterSystem with the tank that was no longer working properly (4yrs). Hopefully this NUAQUA will bit the odds.

Soft well water

I purchased this unit almost a year ago. I’m so happy with it and highly recommend it.

I would spend 60 bucks for a 100 gallons of RO. That does not include the wear and tear on my car ,gas,45 min drive one way. It took minimum mechanical skills to get up and running . Save time and money and pick one up the water taste great!

Mark Hand
Unique installation

As you can see from the pic, this system was not installed under the sink. I installed it the basement below the kitchen. Why? I have two different methods of supplying the unit, option 1 is from my well, which runs thru a water softening system, option 2 is from a spring. Either option is selectable by valves. I also have two outputs to feed, one to the sink and one to an ice maker. As this was the location on my old (+30 yrs) RO unit, this location was perfect.
Everything works great as far as the unit goes. The booster pump ensures a steady supply to me outputs. Only reason for not giving it 5 stars, is that, when I called service, to get the part numbers of the needed mating connectors for the fabrication of a control cable extension for the sink faucet, the service was almost non existent. Nobody could help me and all they could say was not to install the unit the way I did. And almost threaten this install would void any warranty. But when asked if they wanted me to send the unit back, they just reiterated, not to install the unit in the basement. Even though customer serves rating was basically 0, I am researching the proper IP69 connectors needed and will install the supplied facet at the sink once I fabricate the cable extension.
Only redemption for this review would be for NU Aqua to provide me the correct connector information. Then and only then would I change this rating to 5 stars.
