Mix together the butter, honey, sriracha, soy sauce, lime juice, and garlic in a small bowl.
Place salmon in a zip top bag. Pour marinade over salmon and seal bag. Press the marinade around the salmon to coat.
Marinate about 15 minutes, turning periodically to cover all of the salmon.
Preheat air fryer to 400 degrees for about 3 minutes.
Remove fish from the marinade (reserving the marinade) and pat dry with paper towels.
Spray the inside of the air fryer basket with oil (I like avocado oil spray). Place the salmon in the basket. If using individual fillets, make sure they have some air around them and are not touching. This can be done in batches, if you have a smaller basket.
Add salt and pepper, to taste. Air fry for 7 minutes, then check doneness. The salmon will be opaque and will flake.
Meanwhile, pour the reserved marinade into a small saucepan and simmer over medium heat until it thickens, about 2 minutes. Spoon over salmon and top with cilantro before serving.
