Reading through the ETS material (again) on water filters, and basically non-pump water filters are ignored.

I'm soliciting comments on non-pump water filters, particularly the line of squeeze-bottle filters from safewater. Such a system seems to be far less complex, weight less and is presumably more reliable than than a pump, e.g., fewer parts, no moving parts. The sole disadvantage that I see is an inability to draw water from small sources/seeps.

Thanks,
