★★★★★Got great technical service and fixed it!
Spoke with one off the service members, I think his name was Nick. Nick was very helpful, explained a solution, which I was able to do with the help of a friend and his table vice and a trip to the pool store for the rubber ring.

I received unbelievable customer service from Crystal Quest. Nicolas Edgeworth gave me prompt responses to all of my questions and really took the time to help me with everything from selecting the right products, to install, and everything in between. You can shop with confidence at Crystal Quest.

★★★★★We are spoiled
The system we have had for years is great! The water is by far much better than we would normally drink without the filtration. When we go to a restaurant, the water just isn’t the same.

★★★★★Easy Replacement
Easy to install once I could loosen up the canisters.

★★★★★Water filters
Our experience using these items has been excellent. We having been using these filters for about 6 years now due to the fact that we live in a town with terrible water. We realize that we were spending about 800 dollars a year on bottled water while still having to pay our local water bill. A friend told us about Crystal Quest and their water filtration systems. It has changed our lives for the better. We now only spend around 180 dollar per year on the filters and we no longer contribute to the plastic pollution problem. Thank you Crystal Quest.

★★★★★Carbon block filter
This filter and the Multistage under the sink filtration system have been excellent. I'm sure there are other systems out there. But I personally believe Crystal Quest filters are the best. I will continue to use them in the future,
