Preheat the air fryer to 200°C (390°F). In a small bowl, mix olive oil, lemon zest, lemon juice, herbs, salt, and pepper. Brush the mixture onto both sides of each fish fillet. Place the fillets in the air fryer basket, skin-side down if applicable. Cook for 10-12 minutes until the fish is opaque and flakes easily with a fork. Serve immediately with your choice of sides.
