Works as describes!

Watch installation video a head of time. It was very helpful knowing ahead of time what to expect. Installation took me a few hours but I had no surprises.

Happy we got it

We purchased this unit along with the 600gpm RO unit and demineralization filter. Very happy with the purchase and easy install.

Lorenzo Leone
Great product and easy to use

Combined with a filtration system this UV purifier assures good clean drinking water. It's working fine so far. It only turns on when the water is running through it, so you will not be replacing expense, clumsy bulbs every 6-9 months. I am so glad they came out with a UV LED version makes this system almost maintenance free.

Slow to kick in at first

When I first installed this unit with the remineralization unit it was extremely slow for about 2-weeks. It still takes a couple of seconds to kick in but nothing too bad. I love being able to have clean filtered water at the highest quality I can get. This is an excellent unit and I am very satisfied with my purchase.

5 Stage system install

Installing was pretty straight forward with no issues. However I am disappointed with the water flow, not strong enough.
