Wash and trim or break off the ends of the asparagus. Pat dry the asparagus.
Cut or slice the bacon in half so that you have 16 total pieces of bacon (or as many bacon strips you need for your asparagus).
Starting in the middle of the asparagus, wrap the bacon around the asparagus towards the bottom, allowing the top and bottom to peak out.
Evenly place the asparagus in the air fryer basket. Cook for 15-18 minutes at 400°F/200°C, or until the bacon starts to get crispy to your liking and the asparagus is cooked and tender.
