Using a water pitcher with a filter will not only improve the makeup of the water, but also its quality and how it tastes. This means you won’t be drinking water that smells moldy or foul. Instead, by regularly replacing the filter, your water will stay at the correct pH level for it be healthy and tasty. That said, be careful about going too crazy with a filtration system. Some filters go so far as to remove minerals like magnesium, calcium, sodium, and iron that are actually good for your body.
