A screen protector takes the scratches and cracks before they reach the iPad Air 13” (2024) display. A broken protector costs a few francs to replace; a cracked original display costs many times more.
Look for full glue: the adhesive covers the whole surface, not just the edge, so corners don't lift and no rainbow patches form. 9H hardness resists keys and sand. For the iPad Air 13” (2024) the glass fits precisely with cutouts for Face ID and the earpiece.
To protect the cameras too, pair the screen glass with a separate lens protector.
The iPad Air 13″ (2024) is the first ever 13-inch iPad Air — LED Liquid Retina 13″, M2 chip and USB-C. A good case protects the display and the aluminium back from scratches, drops and table edges, and preserves the resale value of your device.
