Individual Bottles: Many people are willing to pay extraordinary prices for the availability and convenience of of certain products. In the home, this does not matter much, but when water companies use ozone to disinfect the water there is no residual disinfectant, so chlorine or another disinfectant must be added to minimize microbial growth during storage and distribution.  If you are concerned about removing any of these contaminants, other strategies will be needed in addition to the KDF media.

Federal standards - Bottled water is regulated by the Food and Drug Administration (FDA which requires manufacturers to submit samples regularly for testing. A filter that removes particles down to 5 microns will produce fairly clean-looking water, but most of the water parasites, bacteria, cryptosporidia, giardia, etc.

The change in blocksize caused the job to run twenty times faster. The length of contact time between the water and the carbon material, governed by the rate of water flow and the amount/volume of activated carbon, has a significant effect on adsorption of contaminants.
