Preheat the air fryer to 390°F for 3 minutes if recommended.
Brush off loose ice, arrange the fillets skin side down in one layer and cook at 390°F for 7 minutes.
Mix oil, lemon juice, Dijon, garlic, paprika, dill, salt and pepper.
Transfer the salmon to a clean plate, pat the top and sides dry and brush with the seasoning mixture.
Return to the basket and cook for 5 to 9 minutes longer, removing each fillet when its thickest point reaches 145°F.
Rest for 2 to 3 minutes and serve with lemon and fresh herbs.
