Dust staying suspended

[RobHannon]

Not sure if this is a problem or even a sign of something else that could be wrong, but trying my top hat out hooked up to a real tool and I noticed that the bulk of the dust stayed spinning at the top of the chamber for a long time. When the DC was turned off everything fell and mostly went past the slot into the bin and I am not noticing anything significant in the filter. Something I should worry about?

I have the same issue, my top hat is less than ideally designed, so the fine dust takes a few trips around the separator, unlike larger chips. As long as the filter is not filling up, it tells you the dust is eventually ending up below the baffle, where you want it, and not in the filter.
