In a small bowl, mix together honey, soy sauce, and garlic powder until combined.
Place the salmon fillets in a dish and coat them with half of the sauce mixture, then cover and refrigerate for 30 minutes.
Turn on the air fryer and set the temperature to 400°F to preheat.
Remove salmon from the marinade and arrange them in the air fryer basket; brush the remaining sauce over the tops.
Cook the salmon in the air fryer for 7 to 8 minutes, adjusting time based on thickness until cooked through.
Serve the salmon hot with the reserved sauce drizzled on top, and garnish with sesame seeds or sliced green onions if desired.
