3M Anti-Glare Privacy Filter for 18.5" Widescreen Monitor

Overview

The 3M PF185W9B is an anti-glare privacy filter designed specifically for 18.5-inch widescreen monitors with a 16:9 aspect ratio. It helps protect sensitive information by limiting the viewing angle to about sixty degrees, ensuring that only the person directly in front of the screen can see the content clearly. This filter also reduces blue light transmission by approximately thirty-five percent, which can help reduce eye strain during extended use.

Its reversible design offers two viewing options: a glossy side that maintains screen clarity and color accuracy, and a matte side that cuts glare and minimizes fingerprints. Installation is flexible with included adhesive strips and slide mounts, allowing for either a semi-permanent or removable setup. The filter also adds a protective layer that resists scratches and blocks dust, keeping your monitor clean and well-protected.
