Preheat your air fryer to 380°F (193°C) for about 3 minutes.
Pat the chicken wings dry with paper towels to remove excess moisture for crispiness.
In a large bowl, toss the wings with olive oil, garlic powder, smoked paprika, salt, and pepper until evenly coated.
Arrange wings in a single layer in the air fryer basket (you may need to cook in batches).
Air fry wings for 25-30 minutes, shaking the basket every 8 minutes, until wings are golden brown and crispy.
While the wings cook, combine hot sauce and melted butter in a small bowl and mix well.
Once wings are cooked, transfer to a large bowl and toss immediately with the buffalo sauce mixture until fully coated.
Serve immediately with ranch or blue cheese dressing and celery sticks if desired.
