> Get a HEPA filter instead. Lots of cooking methods (especially involving high temperatures with fats) produce terrible air quality by themselves that you can only mitigate with either a prodigious vent fan or lots of HEPA filtration. > I know this from measuring it in my own kitchen, air quality would spike to worse than the worst city globally for hours without filtration or minutes with. HEPA filters don't help with NO2 levels. Air filters on the market that advertise activated charcoal are full of it, you need pounds of activated charcoal to make a huge difference, not the tiny little sheet that most filters use. FWIW I have 2 HEPA filters running, they don't help with spicy food either. Someone on HN once mentioned a real charcoal filter they had bought that had several pounds in it, but sadly I lost the comment and I don't remember the product they recommended.
