What do you recommend for deep fryer models in order to eliminate the smell?

Oil and food are the source of the odor you're seeking to eliminate. While you're doing your deep frying, microscopic particles of oil are given off. To eliminate these problems, you want to invest in the best deep fryer with features such as a robust lid.  A fryer with a lid that is used during cooking will help. Also, try using an oil with a high smoking point, and you won't get the unpleasant burning smell.
