Privacy filter keeps confidential information private. Only persons directly in front of the monitor can see the image on screen while others on either side of it see a darkened screen. It is great for high-traffic areas such as airports, airplanes, commuter trains, coffee shops and other public places. Filter is designed to fit wide-screen laptops. Filter includes your choice of two easy attachment methods. Reversible, matte side reduces glare and reflections. Lightweight, thin, frameless design protects your display from dirt, debris and scratches. Clean easily with a soft cloth and water.
