3M Privacy Filter for 23.8" Monitor

The 3M PF238W9B is a privacy filter created for 23.8 inch widescreen monitors. It helps you keep sensitive information to yourself in open offices, shared workstations, and public areas such as airports or coffee shops, so you can work with confidence wherever you set up your screen.

The filter relies on microlouvre technology that limits the viewing field to about 60 degrees. When someone moves even slightly off center, the display appears dark, while you continue to see a clear picture straight on. This simple layer acts as a physical barrier against casual glances and intentional snooping alike.

You can flip the filter to match your environment. One side has a matte surface that reduces glare from overhead lighting and helps hide fingerprints. The other side is glossy and preserves vivid color and sharp detail when reflections are not an issue. Switching between the two takes only a moment, letting you adapt without removing the filter from the screen.

Built for daily use, the PF238W9B stands up to frequent cleaning and handling. It also lowers a portion of blue light, which can ease eye strain during long stretches of work or study without distorting natural on-screen colors.

Installing the filter is straightforward. Use the included adhesive strips for a set-and-forget approach, or attach the slide mounts if you plan to remove the filter from time to time. Either method keeps the filter aligned and secure. Professionals who handle patient charts, financial statements, or proprietary designs, as well as students working in communal study areas, will appreciate the extra layer of visual security that this accessory provides.
