Perhaps a good place to look is at your environmenatal conditions.  If you have a hygrothermograph or datalogger, that
will tell you if the units are helping or not.  What we found in our storage rooms (and what your assessors are probably
most concerned about) is that our levels would rise and fall on a daily cycle.  In the summer, we could fill our portables in
about four hours, so they stopped working at about 9 at night until they were emptied at 8 the following morning (and two
days later on weekends).  The question is, is high and steady better than constantly changing humidity (and I would tend
to favor a stable environment, even if it is a little on the high side).  Moving the air around will reduce the settling of mold
spores (at a previous job, we had a cottage that ran about 95% at 100 degrees in the summer, and we had mold
problems until we put in a fan which started to circulate air).
