Preheat the air fryer to 400°F (200°C) for 5 minutes.
In a large shallow bowl or resealable plastic bag, combine the dry breadcrumbs, grated Parmesan cheese, paprika, garlic powder, onion powder, dried parsley, salt, and black pepper.
In a separate shallow bowl, whisk together the eggs and water until well combined.
Dip each chicken breast into the egg mixture, coating fully, then transfer to the breadcrumb mixture. Press the breadcrumbs onto the chicken to coat thoroughly on all sides.
Lightly spray the air fryer basket with cooking spray to prevent sticking.
Place the coated chicken breasts in a single layer in the air fryer basket, making sure they do not overlap.
Lightly spray the tops of the chicken breasts with cooking spray to help crisp the coating.
Cook the chicken breasts in the air fryer at 400°F (200°C) for 9 minutes.
Carefully flip the chicken breasts over, spray the other side lightly with cooking spray, and cook for an additional 9 minutes or until the internal temperature reaches 165°F (74°C) and the coating is golden and crispy.
Remove the chicken breasts from the air fryer and let rest for 3 minutes before serving.
