Preheat the air fryer to 400°F (200°C).
Pat the salmon fillets dry with paper towels.
In a small bowl, combine the garlic powder, onion powder, paprika, salt, and black pepper.
Brush the salmon fillets evenly with oil.
Sprinkle the seasoning mixture over each fillet, coating the tops evenly.
Place the fillets skin-side down in the air fryer basket in a single layer, leaving space between each piece.
Cook the Air Fryer Salmon for 10–12 minutes.
Check for doneness by gently flaking the fish with a fork. The thickest part should reach an internal temperature of 145°F (63°C).
Serve immediately with your favorite side dishes.
