## Long description

3M PF21W is a privacy screen protector designed for 21-inch displays. The anti-glare privacy filter reduces reflections and limits the viewing angle to protect on‑screen information from side viewing while maintaining clear front-facing visibility. It attaches to the display surface to reduce glare and improve perceived screen clarity in bright environments, making it suitable for office desks, public workstations and home computer setups.
Advantages
The privacy filter limits lateral visibility to help prevent shoulder surfing and accidental information exposure without altering on-screen colors significantly when viewed from the front. Its anti‑glare surface reduces reflections from ambient light sources, improving legibility in well-lit areas. The thin, durable construction provides a protective layer against minor scratches and dust, while the attachment method allows for secure placement and easy removal when privacy is not required.
Suitable for
Open-plan office monitors where confidential information is displayed
Public kiosks, shared workstations and reception areas
Home offices and study spaces requiring reduced side visibility
Environments with strong ambient light where glare reduction is needed

How to use

For removal, gently lift the filter from one corner and store it in a protective sleeve to avoid damage. Reapply following the same alignment steps when needed.
Usage recommendations
