Exhausting your spray booth:

Today I got Tamiya's spray work stand thing-a-ma-jig. So now I want to forsake spray cans forever and start using my airbrush for most everything. So to do that, I'd like to build a spray booth. But for me to use it on most every part, it really needs to be in my work room, which is also my bedroom. Unfortunately my workbench/desk is situated in such a way that venting out a window would be rather difficult. So I was wondering if there was any sort of filtering container that I could vent it into? I was thinking about one of those cheap styrofoam coolers with a filter in the side. Anyone done this (I doubt it, it's pretty ghetto) or anyone have any input on something like this? Just a shot in the dark, I'll probably run the vent across the room to the window after all.

There was an article in a magazine a while back (I think Scale Auto) that described how to make a carbon/water filter. I'm sorry I don't recall all of the details, but it would be what you're looking for.

The general idea was that the exhaust air was pumped into a pail of water that had filter charcoal in the bottom of it. Apparently this cleans it all up.

Anyone else recall this or know more details about this?? Maybe a google search would turn up more info for you.

to filter out the paint particles you can use those airduct filters like the ones 3M makes, i think theyre called Filtrete. as for filtering out fumes you have to use activated charcoal, its the same thing they use in respirator filters. you can find them at aquarium stores and dont need to water for them to work.

this is how activated charcoals work

what you realy need are cooker hood filters, you can get charcoal ones, and they are square.
have the filter at the front and the extractor fan behind, that way you wont gunk up the fan.
plus it will give a large surface area for the air to suck up to, but you will need a good fan or possibly a pair of fans to get the volume of air to pull the paint away
