3M Privacy Filter for 19" Standard Monitor

The 3M PF190C4B is a privacy filter made for 19-inch monitors that use a 5:4 aspect ratio. It covers a viewing area of 14.83 inches in width and 11.89 inches in height, and it relies on microlouver technology that narrows the viewing angle so only the person sitting directly in front of the screen can see the content. Anyone viewing from the side sees a dark, blank display, helping keep sensitive information private in shared spaces.

The filter is reversible. One side has a glossy finish that maintains image clarity in softer lighting, while the other offers a matte surface that cuts down on reflections and hides fingerprints when overhead lights are bright. Switching between the two finishes takes only a moment, giving you flexibility throughout the day.

3M built this model with a layer that helps reduce a portion of blue light without distorting the colors or sharpness of the monitor. The result is comfortable viewing during long work sessions, whether you are editing documents, reviewing patient records, or processing financial data.

A hard coating resists scratches and stands up to frequent cleaning with common screen wipes. Installation is straightforward: slide mounts let you remove the filter whenever you need to share your screen, and clear adhesive strips provide a more permanent, set-and-forget attachment.

Because it shields on-screen data from curious eyes, the PF190C4B is well suited to open plan offices, healthcare reception areas, bank teller stations, libraries, and the tables of frequent travelers who work in airports or cafés.
