Organic fume filters

Linda - Do you have enough space that you can set up a water
filtration unit? You’ll basically be making a large hookah, and
using your fan to draw the air out of the top a long vertical
chamber, with your contaminated air drawn in from the bottom. I’ve
not built one, but they used to be used (1950ish) on laboratory vent
hood systems.
