Mix together garlic salt, paprika, pepper, and olive oil. Using gloved hands, rub mixture all over the filets, including the skin side.
Place skin side down in preheated air fryer basket.
Cook at 400 F for 7-8 minutes. (Up to 10 depending on the thickness of your salmon, ours was done in 8 minutes).Remove salmon from air fryer with fish turner spatula rather than tongs so as not to break the filets.
