Use paper towels to pat the fish dry.

In a small bowl, whisk together olive oil and lemon juice. Brush the salmon fillets on both sides with the olive oil mixture.

Season both sides with garlic powder, sea salt, paprika, and black pepper. Rub the seasonings into the salmon to spread evenly.

Arrange salmon fillets in the air fryer basket, skin side down, with space between them. (If using skinless salmon, line the bottom of the basket with aluminum foil before adding the salmon, leaving the edges of the basket uncovered so that air can flow through.)

Air fry salmon at 400 degrees F (204 degrees C) for 6-10 minutes, until the salmon internal temperature reaches your desired doneness: 125 degrees F (52 degrees C) for medium rare, 130 degrees F (54 degrees C) for medium, or 140 degrees F (60 degrees C) for well done. If you don’t have a thermometer, you can test if the fish flakes easily with a fork.
