This is an ongoing debate on pro and con of RO water. I was considering brands like Coway for my new kitchen but now leaning towards normal filter like 3M or Amway eSpring.

There isn't any scientific evidence to demonstrate the benefits of the energized water. Water filter most important function is to filter impurities such that it is suitable for drinking. If you follow this principle then you don't really need anything extra.

These energized water, alkaline water are mostly originated for JP and KR - two countries where fads are norm. That said, some of the "theories" seem plausible but not proven. I have just gotten the latest Panasonic TK7585 ionized water filter just to try out the difference. At least I know the Panasonic water filter does indeed is a good water filtering device I.e effective in getting rid of harmful substances at least. Ionized water is just an added feature to me

Yes. It is alkaline ionizer. You need to change the filter about yearly bit this depends on the usage. The electrodes once is gone it is gone. You can still use it for normal filtered water but it has no more ionized water

This sounds like a sales pitch to me rather than anything else
