3/11/25.. No issues to date. Still great water and continued "over the top" service by Mark! Thanks! This lil ole lady is super happy!
7/31/25.. I've lived here for over 45 years. We had crystal clear water for about 15 years from the well when we moved in after building the house and after that (for 25+ years) I went through a process of having to find/use a water system that started out good for a few months and then gradually turned in to brown water again. And watching the price go higher for a service that I definitely was not getting.
Since finding out about Advanced Water Treatment and purchasing their system it's still crystal clear and the service is still top notch.
10/20/25. Nothing has changed with my water or the service I received from Mark/Advanced Water Treatment! In fact, I was just thinking this morning how amazing it is that after 2.5 years my awful water is still being treated with amazing results!
3/10/26 If you are having issues with your water you need to think about getting this outfit to come out. As a widow of going on 7 years now I am glad that this is something I do not have to worry about since I don't have a husband to take care of it. Advanced Water Treatment has cleared up my water and is keeping it that way.
6/29/26 Still no complaints. Still receiving AAA+++ service.
Response from the owner:Thanks Susan!

Response from the owner:Thank you Elizabeth!
Enjoy your clear, iron free water!

The best water purifier is the one that meets all the needs of your home. Depending upon what is found in your home water test, a basic water purification system may suffice or you may need a more robust system for high levels of contamination.
What is the best way to purify water?
The best way to purify water is via a multi-step/ multi-filter water purification system. Each step/ filter will do different things to purify your water. If you have hard water, you’ll want a water purifier that has a softening step/ filter. If you have water contaminants, you’ll want a reverse osmosis step/ filter. If you have high levels of bacteria and/or viruses, you’ll want a uv step/ filter as well. It all depends on the needs of your home’s water.
