3M Privacy Filter for Apple iMac 27in, 16:9, PFMAP002

3M™ Privacy Filters provide world-class "black out" privacy from side views outside the 60-degree viewing angle, while creating an excellent viewing experience from straight on views. Designed for full screen monitors with flat glass displays, these privacy filters are reversible between a glossy side and a glare-reducing matte side that helps reduce reflections and hide fingerprints, so you can enjoy pristine image clarity.
