3M 2-way 21.3" Universal Magnetic Privacy Filter for Desktop Monitor, 4:3

The 3M PF213C3B Privacy Filter is tailored for 21.3-inch desktop monitors featuring a 4:3 aspect ratio, measuring 432 mm wide by 324 mm high. This filter restricts the viewing angle using 3M Privacy Technology, ensuring data displayed on the screen is visible only to the user situated directly in front of the device. Viewing angles exceeding approximately 60 degrees result in a darkened, blocked screen image for observers viewing from the side. This functionality makes the filter suitable for safeguarding sensitive information in open-plan offices or high-traffic shared workspaces.

The filter surface is fully reversible, offering the user two finish options: a glossy side for maximum image clarity or a matte side designed to reduce screen glare by up to 99%. Beyond privacy, the filter material helps reduce blue light transmission and provides a durable physical layer of protection against minor scratches and dust accumulation on the monitor screen. Installation utilizes the included 3M COMPLY mounting system, which incorporates both slide mount tabs and removable adhesive strips, facilitating quick application, secure fit, and immediate removal when screen sharing is required.
