Try seasoning a cast iron pan without setting off every smoke alarm...

Reading this reminds me of when I attempted air fryer Brussels sprouts last fall. I had the temperature way too high and ended up with little charcoal balls, lol. My apartment smelled like a campfire for days after that. Now I'm scared to try kale chips, but your method sounds promising. I guess the key is patience and not cranking up the heat for everything.

I looked up the VOC thing once after my bathroom paint job smelled like a chemical factory for a week (my bad). From what I remember, low-VOC is under 50 grams per liter, but that's still enough to stink up a room. And yeah, floor polyurethane is the actual worst, I learned that the hard way.
