Tap water really is awful stuff. The amount of contaminants that we absorb through our skin and inhale into our lungs while bathing is horrific.
When you look at the list below; think about all the tap water that domestic pets (dogs and cats) consume over their lifetimes. It is no wonder that cancer, neurodegenerative and autoimmune diseases are exploding in our pet population.
A good filter is a valuable investment.
