I’m not sure. I tried several poppers including this one and returned them all. Now, I just put virgin olive oil in a pot and kernels on my stove and it does better than any popper!
Don't know about BPA but I was not very satisfied with the quality. The on/off toggle snapped and each time I have used it, there are many, many kernals of corn left that do not 'pop'. I had an Orville Redenbacher air popper previously and it did a much better job.
