Right -- God only knows the number of things were filtered out to
leave me with filtered water.  What's "filtered" in this case is what
was passed through, not what was removed.
I hadn't even thought about "filtered" as meaning the input to the
filtering process until Tom mentioned it, but on a different day, in
a different mood, it might also be what I assumed was meant by
"number filtered".
It's kinda hard to imagine a *more* ambiguous term.
