3M High Clarity Privacy Filter for 21.5" Monitor

The 3M HC215W9B is a high clarity privacy filter made for 21.5-inch widescreen monitors that use a 16:9 aspect ratio. It helps you work with confidence in shared offices, classrooms, clinics, or coffee shops by blocking side glances outside a 60-degree viewing angle, so only the person sitting directly in front of the screen sees the content clearly.

Unlike standard black privacy screens, this model delivers nearly 20 percent more clarity. You continue to enjoy vivid colors and crisp text because the glossy surface on both sides preserves the natural brightness of your display. If long hours at the computer leave your eyes feeling tired, the filter also reduces blue light transmission by about 35 percent, adding a measure of visual comfort without software tweaks.

Installation is quick. Use the included adhesive strips for a semi-permanent setup, or choose the slide mounts if you want to remove the filter regularly. Either way, the fit stays secure and the screen remains easy to clean. A scratch-resistant coating stands up to frequent wiping, so the filter keeps doing its job long after the first application.

For professionals who handle confidential charts, financial data, patient records, or any information best kept private, the HC215W9B offers a practical layer of protection that does not compromise image quality.
