Many many years ago, I thought I was being clever by sticking the house of a vacuum into the box I was using to spray paint minis and having it suck out all the fumes. I thought it was working until the first time I used a white primer(stronger fumes for whatever reason). Turned out while it had sucked the fumes out of the box, it also just threw them back out into the basement I was painting in. Right outside my bedroom. Yeah, didn't sleep well that night.
The other day, it occurred to me that they make respirators for painting. More importantly, those respirators use replaceable filters. Filters that I should be able to affix to a hole in a box and rig a vacuum up to. In theory, the vacuum should keep the fumes from escaping the box while the filter should stop the fumes from just passing through the vacuum.
This all sounds too easy for me to have not heard of it before, so what am I missing here? How bad of an idea is this?
