I’m getting ready to do a major upgrade to my shop and would like some advise and guidance on a air filtration system that I should install to drastically reduce the dust in my shop.  I have a decent dust collection system but I’m looking for a ceiling unit to clean the air so that I can do my finishing in the same area.  Realize that can be hard but I’d like to have a better than reasonable chance. 

So what should I consider.

Thanks
