Doing your own water filtration is one way to get around the need to trust either city supplies or water bottlers. When you filter water at home, you know what kind of equipment you’re using to remove chlorine, bacteria, heavy metals and other materials from your water. A high-quality water filtration unit such as a Tyent ionizer even lets you know when it’s time to change the filter, so there’s no risk of getting a lower-quality product.
