As long as you flush the bacterial buildup out of the filter.  Sitting
overnight the filters incubate a measurable growth of bacteria in the act
carbon filter (and probably others) that may (and may only) contain
pathogens.  About a 2 minute flush each morning does the trick.  If you're
gone a weekend or a month, you still only need the 2-min flush.  (based on
undergrad research on municipal and well supplied household water systems in
1979).
