I’m not super worried about viruses in the water. We get exposed to plenty of those all day long.

You clean the filters by brushing them and then allowing them to air dry.

I also have an RO filter but it requires pressure which may not be available.

Then I guess you don't know about the Norovirus? Its the one that caused all the illnesses on the cruise ships. http://www.cdc.gov/nceh/vsp/surv/gilist.htm Also not uncommon for it to be found in ground water. http://www.cdc.gov/ncidod/eid/vol11no11/05-0487.htm
