I was searching for a whole-house filtration system because of my and my son's sensitive skin. After having a water test conducted (by a separate company), I found out that we have slightly elevated THMs (trihalomethanes). My research led me to this company, and I was excited to buy from them since they are local to me. However, after paying a LOT of money to a plumber to install the BodyGuard unit, it actually made our skin worse. I don't even know how this is possible. I have since disconnected it and it is just sitting in my garage. Customer service has not been helpful despite a couple of attempts to figure out a solution.
