In order for a vac to work, air needs to not just go into it, but out also. what you are getting is the fine dust passing through the filter, and going out with the exhaust air.
You can buy a replacement Hepa filter that will catch a lot more of this dust, and even a pre-filter that is basicly a bag that goes over the filter, that will help as well. Lowes and Depot carry these, as do just about everybody else that sells the vacs. i think the last time i bought the hepa filter for mine, it was around $25 ( the filter bag things are a lot cheaper)
