Preheat your air fryer to 400°F (200°C).
Pat the salmon fillets dry with a paper towel.
Brush each fillet with olive oil and season with garlic powder, paprika, salt, and pepper.
Place the fillets skin-side down in the air fryer basket.
Cook for 7-9 minutes, depending on thickness, until the salmon flakes easily with a fork.
Serve immediately with lemon wedges on the side.
