I'm utterly confused, but I'm not sure if I have this or not.
Now I'm opting for this filter:
Wood, 99.99% @ .3 micron, 24x24x5 5/8" (http://www.filtera-b2b.com/businessfilters/hepa.htm#99.99wood)
That $140ish amount is shipped, which I think is a great deal.
Now, the brochure (http://www.filtera-b2b.com/businessfilters/PDFfiles/HEPABrochure09072004.pdf) gives an example of a test filter and the static pressure to CFM ratings. I'm in luck on this, because the test filter was the same size. They tested 4 filters of diff. efficiencies. For this particular filter I'm getting, it says for 1"-1.2" static pressure, the filter is rated for 275-350CFM.
Now I'm not wanting to blow my filter out and I understand the plenum math for this. But I was going to opt for a 8" Elicent centrifugal fan (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=390120070256&rvr_id=150971667081&crlp=1_263602_304642&UA=M*F%3F&GUID=ab029a5e1250a02668828842ffff416e&itemid=390120070256&ff4=263602_304642). The brochure (http://www.continentalfan.com/docs/AXC-C_Hydro_Brochure_16387.pdf) for the elicent fans (AXC200B) implies that around 1"SP you get about 360CFM. At around 1.25"SP it goes down to about 271CFM.
Now I looked at the other fans above the 8" on that brochure and they all seem to be quite outrageous for this filter.
Now what I wanna know is that if this fan+filter combo would be ok. I was planning on getting a speed controller to get the perfect match. And I figured the fan is a bit stronger, so with the speed controller and prefilter, I would be pretty safe from wear, tear, and overall use for a few years.
Let me know,
I'm ordering everything in the next few weeks, so let me know ;)

Sounds like your on the right track. ^_^ This might help...
