Combine honey, Dijon mustard, garlic powder, smoked paprika, lemon juice, salt, and pepper to make the sauce.
Marinate the salmon fillets in two-thirds of the sauce for 30 minutes or toss until fully coated.
Preheat the air fryer to 400°F (if no preheat option, run for 5 minutes at 400°F).
Place the salmon fillets in the air fryer basket and baste with the remaining marinade.
Air fry for 7-8 minutes depending on thickness until salmon is cooked through.
Serve hot, drizzled with the remaining sauce and topped with fresh chopped parsley if desired.
