We sell a water filtration system that is amazing. It is a three stage reverse osmosis system that does a great job of taking out the poisons and minerals out of the water. We actually tested the water against bottled water and found the filtered water to be cleaner in several cases.
This system is of great benefit particularly here in southern California because we live in a desert and have our water pumped in from far far away and it is infused with chemicals along the way to kill any serious bacteria. The water is also very hard, causing mineral deposits to build up very quickly in water systems and also in our body’s own waste filtration systems.
Also bottled water is not a reliable or cost effective alternative. According to the NRDC “An estimated 25% of bottled water is just tap water–sometimes further treated sometimes not”. Plus think of the millions of tons of plastic used and discarded every year in bottling water. We tend to also think that plastic bottles are inert and harmless when in fact water bottles release VOCs and other chemical as the soft plastic deteriorates.
