3M Privacy Filter for 11.6" Widescreen Laptop

The 3M Privacy Filter PF116W9B is a removable privacy screen that limits side viewing on 11.6" widescreen laptops so only the person directly in front of the display sees clear on-screen content.

Whether you travel, work in open-plan offices, or handle sensitive information in public spaces, this slim black privacy filter reduces visual exposure from side angles while preserving image clarity for the user. It uses 3M microlouver technology to darken the display when viewed off-axis, and offers reversible finishes so you can prioritize reduced glare or enhanced sharpness depending on your environment.

How does this filter protect my on-screen information?

The microlouver layer directs light straight toward the viewer, making the screen appear dark or black from side angles while remaining readable head-on. It acts as a passive privacy barrier—no software, power, or setup beyond attaching the filter is required.

• Microlouver technology blocks side viewing without altering your screen’s resolution.
• Visible data is limited to users within a narrow frontal viewing cone.
• Provides about 1.5× more effective side privacy compared with many competitors.
• Compliant with ISO27001-relevant privacy best practices for visual security.

Will the filter affect glare, clarity, or touch functionality?

The PF116W9B is reversible: choose the matte finish to reduce reflective glare in bright settings or the glossy side to maximize color and sharpness. Because it’s designed for non-touch widescreen displays, touch behavior isn’t intended; however, the filter helps protect the LCD surface from scuffs and dust when attached.

• Matte side reduces screen reflections and eye discomfort in bright light.
• Glossy side preserves higher contrast and color saturation for clearer images.
• Filter adds a protective layer to guard the LCD surface from minor damage.

How do I attach and remove the privacy screen?

Attachment is quick and user-friendly: the filter offers two easy on/easy off mounting options so it stays in place while the notebook is closed and can be removed without residue. The design supports repeated use for travel or shared workspaces.

• Two mounting systems to suit different laptop bezels and user preferences.
• Filter remains secure when the laptop lid is closed, preventing slippage.
• Easy removal for cleaning or storage—no adhesive damage to the display frame.

What size laptop screens does this model fit and how do I measure?

This filter is made for an 11.6" diagonally measured widescreen display with a viewable width of 10 1/8" and height of 5 11/16". For an accurate fit, measure only the visible active screen area—not the bezel—and select the filter that matches those dimensions or is slightly smaller.

• Designed for 11 5/8" diagonal widescreen displays (viewable W10 1/8" × H5 11/16").
• Measure the viewable screen area (exclude the frame/bezel) for correct sizing.
• Choosing an exact or slightly smaller filter ensures a secure fit without overlap.

Who is this for: The 3M PF116W9B is intended for professionals, students, and travelers who need reliable visual privacy on compact widescreen laptops. It’s a practical choice for people working in airports, coffee shops, hospitals, government environments, open-plan offices, or any shared workspace where shoulder-surfing is a concern. If you want simple, reversible privacy that also reduces glare or enhances clarity on demand, this lightweight, made-in-USA filter is designed to balance confidentiality and usability without software or power requirements.
