Are carbon filters a source of Legionnaires Disease?
AC (Activated Carbon) Filters have been found to be a source of Legionnaires Disease when they are not maintained, as have standing pools of water such as are found in air conditioners. The problem with standing water is the chlorine evaporates or dissipates, and there is no long lasting (latent) bacterial protection. The CL Free Water System puts copper ions into the water to provide the latency that chlorine does not. The copper ions don’t evaporate or dissipate, so your protection remains. The CL Free Water System’s AC Filter backwashes itself completely, automatically.
