how does this level of filtration compare to "katadyn" filtration quality, as i,ve used this type on very suspect water (as in cholera and dysentery) and come through unscathed.
ignore this question as i just checked out the info available here http://www.katadyn.com/water-knowled...hnologies.html
combine a sand spear with filtration to 1 mycron with a ceramic katadyn filter and you will have some of the purest potable water available. with pre filtering to to 1 mycron you will have very little maintainence on your ceramic filter.
