I do this several times a week as a prevention. The learning curve is ugh, but once the nose is clean, it is an almost enjoyable experience.
Also, it seems to snuff out beginning colds really efficiently, though not 100 per cent reliably.

That said, I feel fairly safe, because I
a) run the water through a fine filter < 1 micron first,
b) boil it anyway, just to be sure,
c) these amoebas don't like cold running water and tend to live in warmer, stagnant waters only, so a typical municipal water system won't be infested.
