We have a full house water filter system with he crystal rod andd activatied charcoal for the hard water in San Diego. There is no mineral deposits on the faucets, since the minerals are suspended. The water tastes good without the stomach upsets from the cancerous chloramines. The pH is too alkaline. They want to keep the pipes from leaking. Too hell with your health!

I believe it is a Lifesource system, but there are no magnets involved. Poor Customer Disservice after you get it.
