“...they passed the water through a pair of increasingly fine filters — with pores 0.2 and 0.1 microns wide...”
So what they are saying is my 99.99% water filter is really only about 49.99%.
I’m guessing probably not because they say most bacteria are larger. However, I wonder how many of these new bacteria cause disease? Even if your filter will have to be re-rated a 95% filter, say, are any of the 5% that get through pathogens?
