Preheat the air fryer to 400°F.
Rub each fillet with olive oil and season with garlic powder, paprika, salt and pepper. Place the salmon in the air fryer and air fry for 7-9 minutes, depending on this thickness of the salmon. A good rule of thumb is to cook salmon 4-6 minutes per half inch of thickness.
Open basket and check for desired doneness with a fork. You can return the salmon for another 1 or 2 minutes as necessary.
Note: Take salmon out of fridge 15 minutes before cooking, so that it cooks evenly. Cook till 145° in the middle.
