Kap,
I've heard of the idea about a filter and a box fan and posted about it. Nice idea in theory but I wouldn't consider doing it. Way too many problems with the idea.

This can actually have decent results if you buy a pre-flter mesh and attach everything correctly. Without a pre-filter, your main filter gets clogged with coarse dust instead of fine particulates.
Something like this is easily vacuumed http://www.amazon.com/14ALL-Filter-Repla..._2?ie=UTF8&qid=1397403930&sr=8-2&keywords=carbon+pre+filter
The downside, it is not as efficient as a sealed forced air unit and the filters may not last as long since the baffles are thinner.
