Very convenient.
One thing that can be improved is the size of the water tank. I wish it was larger.

Love it

I love this machine. My water is great and it has cold and hot. I’m not sure how long the filters will last so I’m getting some spares.

Nicole Mortensen
Great Machine!

I really love this machine! It is very easy to use. I have used others that require you to empty the tank constantly and it was very annoying. This is so easy, you just add the water and go. And it tastes as good as their other filters too.

NU AQUA Reversed Osmosis Countertop

I am exceptionally pleased with my new filtration system It is a countertop and it is easy and efficient.
I have been using tap water (city utilities) without a filte for 7 years. I wish I had started using reversed osmosis 7 years ago. Impressive---As long as it does not dysfunction any time soon

Aqua review

Good RO system. Only real downside is refilling the reservoir, but other than that it works great.
