The new 3M^™ Desktop Privacy Filter enables you to keep your secrets secret anytime. 3M’s patented microlouver technology works like mini-blinds on windows. The screen is clear, crisp and bright when viewed by the user. When viewed from the side, the microlouver feature blocks the information to reveal a dark black screen. A unique feature designed to safeguard sensitive information from prying eyes, the 3M Desktop Privacy Filter is ideal for anyone who needs to work in the public and yet requires privacy.
