Importance of Filtering Your Water

Filtering your drinking water is certainly more important in some parts of the world than in others – but the reality is that most people can benefit from adding a filter to their setup. Some potential benefits include:

Improved Taste – Filtered water simply tastes better than standard tap water. Unfiltered water can take on a variety of undesirable flavors – chemical/chlorine tastes, earthy/dirty tastes, bitter tastes, and more. By purifying and removing contaminants from the water, filters can help to significantly improve taste, odor and appearance of your drinking water.

Safety and Health – Unfiltered tap water can contain a host of unpleasant and potentially harmful contaminants. The most common is chlorine, which is added to most water supplies to kill bacteria (and is also linked to cancer and many other health concerns). Other potential contaminants include heavy metals like lead and aluminum, bacterias, sediment from organic particles, and more. Filters can effectively remove many of these contaminants, which can potentially improve your health and reduce your risk for various medical concerns.

Peace of Mind – Peace of mind is a priceless commodity, and knowing that you’re drinking the cleanest water possible is a very good source of this rare feeling.

Cost Savings – Counter-top water filters are affordable, and the upfront cost is offset by savings from less purchases of bottled water and other drinks. If you’re buying drinks regularly because you don’t like the taste of your tap water at home, a home filter can save you a ton of money!
