That's pretty cool. I just assumed that there would have been too much airflow around charcoal pieces for them to help enough to be worthwhile.

Depending on what you're filtering, you might even be able to keep using the charcoal afterwards. I know some things like radon can be pulled back off the charcoal just by pumping on it with a vacuum pump for a while, so if you have two filters and a good pump you can use one for filtering while you pump on the other and just keep switching back and forth without ever having to swap the charcoal.

I would hazard a guess that you could use something similar to a bathroom vent adapter to keep rain coming in and whatnot, and ducting to get through insulation and whatnot safely. Wouldn't be surprised if there are some building codes that would specify what you want to do for a generic vent.
