So, what do you think, is tap water cleaner than bottled water sold at stores? Whether you think the answer is "yes" or "no", you could be right. It depends on several factors.

First, it depends on the brand. Aquafina, Dasani and Pure life are bottled by Pepsi, Coca-cola and Nestle. They use public sources and a reverse osmosis filter. Then they add in some potassium and sodium to improve the taste, since reverse osmosis de-mineralizes.

Reverse osmosis does very little to improve the quality of publicly treated supplies. It does not remove chemical contaminants, like chlorine and THMs. You need granular carbon and special resins to trap those contaminants. That brings up another question.

If you have an effective purifier in your home that includes granular carbon and other filtering media, is tap water cleaner than bottled water sold at stores? The answer to that question is still a little iffy. Granular carbon and resin filters are not the only steps that are necessary.

Other than the brand, the quality of bottled-water depends on the purification method that they use. If they do not use either reverse osmosis or submicron filtration, then there is no guarantee that there are not cysts in the bottle. Cysts may also be present in any publicly treated supply. They are protozoa that are not affected by chlorination or other public disinfection measures. At home, the best choice is submicron particle filtration, simply because it is less expensive and does not create the wastewaters that reverse osmosis systems create. So, you have this question.

Is tap water cleaner than bottled water sold at stores when you have a submicron particle filter, granular carbon and other filtering media? There is still one more step that you need to take to insure purity.

Traces of lead, copper and other metals are commonly found in tap-water. They spoil the taste and lead is bad for your health. An ion exchange step will remove these metallic traces and replace them with ions of potassium and sodium. So, what you have is something that tastes as good, if not better than bottled. It tastes a lot like spring water.

Now, if you ask this question; is tap water cleaner than bottled water sold at stores and you have a multi-stage purifier that includes ion exchange, granular carbon, special resins to trap THMs and a submicron particle filter...the answer is "yes".

Your home filtered tap-water is cleaner because it is not stored in a plastic bottle. The plastic leaches impurities into liquids stored within them. BPA and phthalates are the most common chemicals found in jugs and bottles of water. They are endocrine disruptors, which are particularly hazardous to children. THMs, as you may know increase the cancer risk and many bottles test positive for them, as well.

Knowing all of this, what do you think now, is tap water cleaner than bottled water sold at stores? If you take the right steps, it sure is.
