Preheat the air fryer at 400˚F/204˚C for 5 minutes.
Mix together the mayonnaise with the herb and garlic seasoning in a small bowl.
Pat dry the salmon fillets with a paper towel and place the salmon in a lightly sprayed air fryer basket or on top of a foil sling in an air fryer basket.
Spread the herb mayonnaise mixture on the top of the salmon filets. Top with parmesan cheese.
Cook in the air fryer at 350˚F/175˚C for 8 minutes, or until the salmon registers at 145°F/62.7°C with an instant read thermometer.
