3M Privacy Filter for 23.5" Monitor

The 3M PF235W9B is a privacy filter that fits a 23.5-inch widescreen monitor, giving you a straightforward way to keep on-screen information shielded from curious glances. When you sit directly in front of the display, everything looks normal, but anyone who tries to view the screen from an angle greater than 60 degrees sees a darkened, unreadable surface. This makes it an easy choice for shared offices, reception areas, libraries, or any workstation that faces foot traffic.

3M uses a microlouver technology that guides light so it reaches only the person seated right in front of the monitor. Because the filter is reversible, you can choose the glossy side when you want colors to pop or flip to the matte side when you need to cut glare and hide fingerprints in bright rooms. Either way, the filter helps reduce up to thirty-five percent of blue light, which can make long editing sessions or extended spreadsheet work feel easier on the eyes.

Installation takes just a few minutes. You can seat the filter inside the monitor’s raised bezel and secure it with the included adhesive strips, or slide it into optional side mounts if you prefer a solution you can remove quickly. The filter is engineered for repeated cleanings, so it stands up to daily use in busy environments such as healthcare check-in stations, financial service counters, or open-plan offices where screens are cleaned often.

The PF235W9B is sized for 16:9 monitors with a 23.5-inch diagonal, so double-check your screen’s active area before ordering. Once in place, you gain dependable privacy, a clearer view straight on, and a monitor that looks professional in any workplace.
