Hey there, thanks for reading my Instructable and for your comment! The blower motor that I used states that it provides 420 cfm of air flow so in a perfect world at that rate it should be able to clean all the air in my shop in less than 5 minutes. That would be a bit of an exaggeration though because 1. I don't think that it actually does provide 420 cfm (more like 300 cfm) and 2. Once the filters get caked with sawdust, they restrict the air flow quite a bit. I think that with my setup and with clogged filters it recirculates more like 200 cfm. With all that said, my shop is 12' x 16' x about 8' tall (almost 1600 cubic ft) /200 cfm it should take more like 10 minutes to clean the air. I mounted mine pretty centrally and near my biggest sawdust maker (my miter saw) and I run it contin...

I mounted mine pretty centrally and near my biggest sawdust maker (my miter saw) and I run it continuously while working. I notice that after about 10 to15 minutes the air is dust free. I leave it on sometimes over night and I come back in to my shop the next day to a fresh clean air shop. Matthais mounted his air cleaner(s) in the corner of his shop which I think is a lot less effective. Hope this helps!

I use Sketchup for all my 3D modeling of projects. It used be called Google Sketchup but I think they sold it. It is a free software and you can download it just by searching sketchup in google.

This is such a great idea! I wish I saw this last week... I used my drywall saw to carve pumpkins this year but I shall make a few of these to use next year!
