I'm not going to bother with a filter. My bench is right next to a
window. I'm going to build a system that uses:
* a board to go in the partially-opened window, edged with
weatherstripping, with a hole in it for
* a dryer vent to keep the cold air out when I'm not using it, which
is coupled to
* a length of flex dryer hose, connected to
* a round electric plaster ring, used to mount
* a 110V muffin fan, with another
* round electric plaster ring on the other side, connected to
* another length of flex dryer vent.
Then I'll put the fan assembly inside a box filled with foam for noise
