Bottled water and the potable water produced by an RO system certainly have differences in their taste. As we all know, there is very little in the way of standards for bottled water. This is because of the sheer variety of bottled water that’s available, which includes artesian water, mineral water, and spring water among others. These several variations are regulated differently, so you can expect them to taste a little differently as well. It’s always a bit of a gamble when you purchase one of these waters for the first time when it comes to how they taste. However, you can count on each option offering you a level quality that exceeds ordinary tap water. As for the potable water produced by an RO filtration unit, you can expect there to be a consistency of taste and quality. It will remove those impurities that can ruin your water supply.
