I wanted an air fryer, so I got the same one my friend has last year, one made by PowerXL. Mine produced this horrific chemical smell that filled up the whole house and soaked into the food. Reddit told me that it just needed to be variously washed or run a few times and it would go away, but it never did. I had to return it.

I suspect the plastics used were changed, or some preconditioning process was skipped to get more units out for a Black Friday sale or something. I haven't revisited the product category since.
