Pat the salmon fillets dry with paper towels and set aside.

In a small bowl, whisk together the maple syrup, Dijon mustard, garlic powder, and smoked paprika until smooth.

Brush the olive oil evenly over the skin side of each salmon fillet.

Flip the fillets and brush the flesh side generously with the maple Dijon glaze, reserving about 2 tablespoons of glaze for later.

Season the glazed salmon lightly with salt and black pepper.

Preheat the air fryer to 400°F for 3 minutes.

Place the salmon fillets skin side down in a single layer in the air fryer basket, leaving space between each piece.

Air fry at 400°F for 7 minutes.

Slide out the basket and brush the reserved glaze over the tops of the salmon fillets.

Return the basket and cook for an additional 3 to 4 minutes, until the salmon is opaque, flakes easily with a fork, and the glaze looks lightly caramelized.

Transfer the salmon carefully to plates, squeeze lemon wedges over the top, and serve immediately.
