advice needed on homemade air filtration unit


Hi all, I need help/advice...
I just got an old furnace blower assembly with a 990 rpm 240 v motor. I want to build an air filter unit.
The squirrel cage is 12" X 12" and I just hooked up a 1745rpm 115v motor. The original motor was rated at 990rpm. Is the new motor going to give me better result by spinning the squirrel cage virtually 2X faster? I was wondering if I could get away with a unit having filters on three sides?
Is there any sites on the web that show IN Depth, CLOSE UP photos on how to construct a unit?
thanks for any suggestions/help

We did the following for brazing fumes but much of the expertise these companies supply will be applicable to your use. I don't have any connection with any of these and, when we did this, the information was free.

Air Filtering Equipment
Equipment Choices You can start as I did with a simple fan and a metal stovepipe. This is very easy and cheap to install. The drawback is that it usually sucks a lot of warm air out during cold weather.

it's a 1/3 HP motor... I plugged it in, and it runs real smooth, but when I put a paper towel close to the sides, well, let's just say that I wasn't too impressed with the drawing power of the fan...
if any one can help, it's you guys/gals on this board!
