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

The 3M PF185W9B is a privacy filter built for 18.5-inch widescreen monitors that use a 16:9 aspect ratio. It helps you work with confidence in open offices, classrooms, hospital stations, or coffee shops by keeping on-screen information visible only to someone sitting directly in front of the display.

At the heart of the filter is microlouver technology that narrows the viewing angle to about sixty degrees. Colleagues or passersby who glance from the side see a darkened screen, while you enjoy an unrestricted view of your work. This simple layer of security is especially useful when you handle client records, financial data, or any content that should remain private.

The filter also reduces blue light by roughly thirty-five percent, which can help ease eye fatigue during long sessions of spreadsheet work, coding, or content creation. When lighting conditions change, you can flip the filter between two surfaces: a glossy side that preserves clarity and color, or a matte side that cuts glare and disguises fingerprints.

Installation is straightforward. The construction is lightweight and frameless, and 3M includes adhesive strips along with slide mounts so you can choose a semi-permanent or easily removable setup. Once in place, the filter adds a protective layer that resists scratches and blocks dust, helping your monitor stay clean and free from minor damage.

Whether you need to safeguard sensitive information in a busy office or simply want a more comfortable viewing experience at home, this filter delivers practical security and screen protection without adding bulk.
