The Fellowes PrivaScreen Blackout Privacy Filter helps your business conform with data protection laws and prevents snoopers spying on what you're looking at on your computer. It presents a solid black reflection for viewers at the side, while remaining crystal clear for users viewing from directly in front. It also helps prevent damage to the screen, and the matte reverse side can reduce glare as well. Simple but sturdy tabs make it easy to attach and remove when needed.
