Add a fitted protective film to a 13.6-inch MacBook Air display without selecting a generic screen-size range. CELLAIRIS 11-0078528 is a screen protector film specified for the MacBook Air 13.6-inch screen format. Its 16:10 display compatibility matches the proportions used by the 13.6-inch MacBook Air, helping buyers select an accessory intended for that notebook display size. Screen-protector film addresses the exposed display surface, where contact from routine opening, closing, cleaning, and transport can affect the panel area. The accessory format is relevant when a user wants display-surface coverage while retaining the laptop's existing enclosure and display assembly. Fit matters on thin-bezel notebooks because a protector sized for a different diagonal or aspect ratio can leave uneven margins or extend beyond the visible display area. Within CELLAIRIS screen protection options, this version is distinguished by its MacBook Air-specific 13.6-inch sizing rather than broad laptop compatibility. Match the installed computer to the MacBook Air 13.6-inch designation and 16:10 screen format before selection. The product is a display film accessory for the notebook screen, not a replacement display panel, laptop case, or keyboard cover.
