Sorry if I wasn't clear. I'm not using a grow tent. I have something similar to this spray booth. For filtration, it uses furnace-type filters and a couple of fans in the back to pull the overspray through an exhaust hose which ideally should be vented outside. Running the vent hose to a window or knocking a hole in the cement wall for the hose aren't options so I just have the air recirculating back into the room. The filters seem fine for acrylics, but they likely won't trap the vapors from lacquer paints so what I'm wondering is if the filter I linked to in the original post would do the job. The filter is marketed toward use in a grow room, but it seems like it may be a possible option especially if the furnace filters are capturing the particulates and the charcoal filter only has to worry about the vapors. If not, is there something else I can add to this setup or some other solution entirely that would eliminate or at least greatly reduce the vapors?
