3M Privacy Filter for 21.5" Monitor
- In stock
The 3M PF215W9B is a privacy filter designed for 21.5 inch monitors that lets you work confidently in busy settings without worrying about shoulder surfing. It relies on 3M microlouver technology, a grid of louvers that are tiny and precisely spaced, to narrow the viewing angle to about 60 degrees. When you sit in front of the screen you see crisp, accurate images; anyone to your left or right sees a darkened display.
Beyond privacy, the filter helps with everyday comfort. It can cut blue light by up to 35 percent, which reduces the visual fatigue that often comes from long hours of reading documents, coding, or editing graphics. If glare is a problem, flip the filter to its matte side to diffuse reflections and hide fingerprints. When you want the most vivid color, use the glossy side instead.
The sheet itself adds a physical barrier that takes the hit from scratches and smudges that would otherwise reach the monitor glass. You can clean it repeatedly without clouding the surface, so the filter stays clear and effective over time.
Setup is straightforward. The box includes adhesive strips for a semi-permanent mount and slide-on tabs if you prefer to remove the filter when collaborating. That flexibility makes the PF215W9B useful in open-plan offices, coffee shops, libraries, healthcare stations, and anywhere else you need to handle private information on a shared desk.
