The water is very good

The water quality is very good. What they can improve is to assume that everyone can do the installation for themselves. In my case, I already had a filter installed and I wanted to change it. It was very difficult to find a service at a fair price for them to install and the NU support in this case was minimal. Once this is overcome, I must say that the system and the water quality is very good.

Hi Luzmila,

We truly appreciate your valuable feedback here at NuAqua!

It's fantastic to hear that you are actively using our Reverse Osmosis System and are continuing as a filter subscriber.

Our RO systems are designed as a DIY project, recognizing that not everyone may be a handyman to install such units or replace filters when they reach the end of their service life.

To assist you further, we have compiled a set of informative YouTube videos on installation that we believe will be immensely helpful. Please find the links below:




Rest assured that your feedback is invaluable to us and will guide us in enhancing both our product and service.

Alkaline in home

I am able to access Alkaline water in my home, very helpful, saves me driving to the waterstore and lifting heavy gallons. There was a small leak when it was first installed and * was asked if this system was referbished, I replied no, I purshed it new. It has not leaked again, although I turn the water sourse off after each use.
