These 3M MacBook Pro Gold Privacy Filters fit MacBook Pro notebooks, from 2009 to the present, to let you work privately in public places, providing more privacy and clarity than competitive privacy filters. Screen data is visible only to persons directly in front of the monitor. And while keeping on-screen information private, they also protect the screen from dust and dirt. The filter application system features an optically clear adhesive designed specifically for display screens. Testing proves that, when kept clean, filters can be repositioned hundreds of times.
