I'v taken apart and started cleaning some activated carbon air filters. Built in a way I can simply pop em in the oven for a few hours to clean, then re pack. Issue comes down to the off gas created by this process. It's a pungent odor that burns your eyes and lungs. Nothing causing serious long term damage (not much more then i'v already done) but still harsh. Any idea what this is? I assumed it would just be everyday hydrocarbons from day to day stuff, but this is just bad.
