Filter Your Water.
Filtering your water is important because you can’t necessarily taste or see contaminated water. The Environmental Working Group recommends the following to obtain cleaner drinking water: research your local water supply for possible contaminants; look for a filter that can remove the contaminants in your water supply and fits your budget; and drink tap water out of a reusable water bottle made of stainless steel or BPA-free plastic if you’re on the go.
