I must admit I don't know what zero-b water purifier is so I went to google and typed in zero-b water purifier. Apparently this is manufactured in India and is a form of ion exchange (at least that is the company name). I suggest you google the word and read those sites. There is a wealth of information there and you should be able to pick up advantages quite easily. Disadvantages may be harder to find since these are commercial sites.
