Water filters are relatively inexpensive and improve the overall taste of your tap water as well as the smell, and appearance. Many filters will also remove some harmful chemicals found in your drinking water. Currently there isn't a better way of ensuring your drinking water and cooking water is as healthy as possible for you and your family. Compare a glass of bottled water to a glass of tap water. Look at the color, clarity and then smell both of them. Chances are, your tap water will be cloudy, and may smell of bleach.
