Preheat air fryer to 375 degrees F. for approx. 5 minutes.
Pat chicken dry with clean paper towel.
Combine salt, onion powder, garlic powder and paprika in a small bowl. Stir to combine.
Drizzle chicken with olive oil and rub all over. Season generously with the seasoning ensuring the chicken is fully coated.
Place chicken thighs in air fryer basket and let cook 7-9 minutes per side, but start checking the internal temperature after approx. 13-14 minutes just in case your air fryer runs hot. Remove from air fryer when chicken reaches an internal temperature of 165 degrees F (Note: I like to take mine out just a few degrees under 165 - the residual heat will continue to cook it while it rests). Set aside on a plate and let rest 5 minutes before serving.
Notes

Storage: store leftover chicken in an airtight container in the refrigerator for up to 3 days.
Internal Temp. of Chicken: chicken is fully cooked when it reaches an internal temperature of 165 degrees F. at it's thickest part.
