I live in Bombay, India. We boil our water here, and have done so for many years. I'm wondering if a serious water purifier e.g. RO + UV would be a better way to go. In this context, better means, better for the health of the human (or possibly animal) who is consuming that water. We occasionally have international guests, and sometimes they seem unhappy with boiled water as a option. Or is both boiling and purification the best way to go?
There is some discussion of this on the net, but I'm looking for a detailed answer, with pros and cons. I haven't found anything like this. Also, some of the answers I've felt have been on sites which might be biased, like sites selling water purification technology.
An Indian-specific answer would be ideal, but not necessary. I do know that Bombay water is supposedly very bad. I've never tested it, though.
As I understand it, the main disadvantage of boiling water is that it doesn't get rid of dissolved solids and other possibly dangerous impurities. And the corresponding disadvantage of RO water purification is that it gets rid of all minerals, which is presumably bad. And it apparently possible to remineralize the water, but I don't know how much of an issue it is in practice. There might be other issues that I'm not aware of.
