The vacuum works so well, that the small amount of dust that leaks and is caught by the filter is not a "big" deal. Since I started using the bags from the pack I bought, not that came with machine, I have not noticed any leakage. The 'average' person, who is just trying to get the job done, and is not interested in vacs will never notice the issue. I feel sure Aerus will make changes to their bags and send anyone who calls customer service a new pack. Having said this, yes of course this problem should never have happened! But, the platinum is still a design success, and I feel will prove to overcome any shortfalls. Just my thoughts..
