A filter will take out any sediment, but the real problem is the dissolved

Yea, I agree. I have one of their "pad" humidifiers (I don't
think they make a "spray" type. After use there is a fair amount of
dusty deposits on the pad. I suggest that the OP may want to replace
their pads more often and that might help. I replace mine once a
year. They don't do too bad, because the over supply the water needed
and drain out the excess so it does not cause as much of a problem.
In my case I don't have a problem beyond the humidifier area.

A second thought would be to increase the amount of water delivered
so more drains out. That could prevent the problem as well.
