Bottled Vs. Regular Water - as part of the expert series by GeoBeats. Looking at the differences between regular water and bottled water, there is really no difference. The biggest differences that I have found are with convenience and taste. So, of course, your bottled water is going to be more convenient because you can take it anywhere and most consumers tend to like the taste of bottled water better. So, as long as you are not dealing with well water, then your regular water and your bottled water are basically very similar. The cost benefit is, you are going to spend more money with your bottled water. Now, I will have to say they are making these filtration devices that you can take on the go now and so, you can have that filtrated water if you prefer that, and have that on the go. But, overall, your regular water that comes from the faucet is going to be much less expensive than your bottled water.
