"Good filter" is a relative term. Maybe you could do it if you "filtered" the water with a $10M reverse osmosis membrane? The filters I buy all say "do not use with unsafe water" or some similar phrase.
- wtallis 8y agoFilters for camping/outdoor usage are less than $100 and most of them are explicitly sold as suitable for use with dirty water. You get a disclaimer that they'll be slower and need to be replaced more often when used on dirty/cloudy water, and sometimes they also advise a chemical or UV treatment be used post-filtering if there are concerns about viruses.

- mattkrause 8y agoThere’s a big difference between those and, say, a Britta filter.
