For marinade, mix the first 6 ingredients. In a shallow bowl, combine salmon and 2/3 cup marinade; refrigerate 30 minutes, turning occasionally. Reserve remaining marinade for basting.
Preheat air fryer to 325°. Place fillet on greased tray in air-fryer basket; discard remaining marinade. Cook until fish just begins to flake easily with a fork, 15-18 minutes, basting with reserved marinade during the last 5 minutes.
