Clean water, works great

The system works great and the water tastes perfect, no problems at all.

Great, must have

Great filter, looks awesome on my kitchen counter and I love having crisp clean water all the time.

Good filter that works great

I really like this filter, it works great. It's easy to assemble, everything that you need is included.

Best tasting water

This water tastes the best of any filter I've had. No chlorine taste, which is so great. Also it's incredibly easy to assemble which made it fast to set up and take anywhere.

ProOne Big

Super happy with this system. Feels really good to be drinking clear water, even my pets are benefitting. I ordered a few extra filters so that I can change them when I need to without having to worry about if they'll be available in the future. Everything arrived nicely packaged and was a breeze to assemble. It's a must have!
