I just responded on your comment on the other post so this will be a repeat for you but for everyone else it's new info.
I built a CR box with a decently powered box fan and 4 20"x20" filters. Here is one link. For anyone who still uses reddit, the CRBox community has some cool builds posted with computer fans but, I won't link that because I know most of us don't like going to reddit.
I have noticed less dust overall in my house however, I need new furnace filters, and I've done some drywall work so that less dust was short lived.
Edit to add a wiki link as well.
