Subject: Furnace Filter dust filtration efficiency - info.

I am building a fine dust collector for my woodworking shop.  I plan to
use an old furnace blower and I need to select an appropriate filter
system to filter the fine dust particles out of the air.

I would plan to use a prefilter (Normal furnace filter) and I am
wondering if someone knows to what level of filtration a basic pleated
replacement filter provides. 

I went to the local building supply store and found the basic pleated
filters and then I also looked at Glasfloss's line, Auer line and
Honeywell of the wider/thicker pleated filters, but I could not find any
information on their efficiency or what level of microns they filter
down to.

The Glasfloss line says they are for every application requiring medium
ASHRAE efficiency.  Sorry, but that told me nothing.   Any help there?

Any idea where I can get more info or a suggestion on a filter?

thanks

I don't know where you are located, but in the US, HEPA filters are
commonly available.
