I don't want to end-up like this guy , but out the other end!
Thats an entirely different situation than filling from a domestic supply.... and its still a relatively poor choice. 1,0ÁM or better 2,0ÁM--->0,45ÁM ("absolute" or 100% filtration rather than a 'nominal' or arbitrary ÁM rating) is the usual standard for filtration from 'unknown' sources. Biologic contamination is best satisfied by filtration before it enters the tank, where it 'multiplies'. A filtration system within a distribution system is a 'microbiologic concentrator'.

BTW - enjoy your waterborne illnesses.
