Most tap water is far from pure, containing numerous chemicals, metals, solvents, herbicides, pesticides, heavy metals, arsenic, and even pharmaceutical drugs like anti-depressants. Filter the tap water in your kitchen and bathrooms to avoid consuming or soaking in these hazardous chemicals. Do your research and make sure the filter gets out chlorine, metals, and fluoride too. A good, NSF-certified, solid carbon block filter should do the trick. Remember to store filtered water in glass or stainless steel containers, NOT plastic, and add a pinch of sea salt to remineralize filtered drinking water so you absorb it and don’t just pee it out.
