Importance of Water Filtration

Taste – Filtered water typically tastes significantly better than unfiltered tap water. Tap water can take on a variety of unpleasant flavors – but it may not be noticeable until you try something better! Good filters can reduce the taste of chlorine and other chemicals, as well as metals and minerals that could be contaminating the taste of your water.

Safety – Depending on where you live, how old your pipes are, etc. your water could contain any number of potentially harmful contaminants. Even things that are added to water almost everywhere, such as chlorine, can cause harm and are linked to an increased risk of cancer.

Peace of Mind – Nothing beats knowing that you’re drinking clean, pure and safe water. That peace of mind is priceless – and it may actually inspire you to drink more water!
