The lady in the article got the infection after using a water filter.
This leaves 2 possibilities that I can see.
1. The filter didn't do it's job. I thought that a good filter would filter all organisms (or like 99.9%). I'm told by people that you can drink out of a swamp or mud puddle with a good filter.
2. The filter does work, but she didn't maintain her filter. Maybe the dirty filter actually was a nice place to cultivate the amoebas? I would be curious if an unchanged filter can actually increase your chance of infection. At best though, the dirty filter wasn't able to filter this organism.

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.
