Heres a simple DIY one - if you have cows for the cow dung in Chile...

CLAY-COFFEE Water filter
€ mix equal parts coffee grounds with clay to make filter containers with
finger-thick walls
€ fire containers in dried dung : pack pots in straw with dry cow dung below
and covering - Cow dung burns at 950 deg C ­ firing time approx 1 hr
€ Coffee grounds burn off during firing leaving sufficient cavities for
flow-through and enough clay to filter out bacteria.
€ 94.5-99.6% ecoli removed with clay-coffee filter
doesn¹t filter out viruses
