Display Privacy Filter eSTUFF GLBM21483273 21.5 inch Anti-Glare

Protect your screen and your privacy with a magnetic anti-glare privacy filter designed for use in offices and on the move. This screen protector limits the viewing angle to prevent shoulder surfing and helps keep login credentials and confidential information hidden from unintended viewers while maintaining visibility for the device user.

Advantages

The privacy filter reduces blue light transmission by approximately 51% (±5%) to help decrease eye strain while retaining clear on-axis viewing. Its anti-glare matte surface reduces reflections and improves visibility under bright lighting. The magnetic attachment allows easy installation and removal without adhesive residue, making it suitable for temporary use or shared devices.

Key specifications

• Blue light reduction: 51% (±5%) at 440–460 nm
• Surface finish: Anti-glare matte
• Attachment method: Magnetic

How to use

Place the magnetic privacy filter onto your device screen, aligning it with the display edges until the magnets hold it securely. For best privacy effect, position the device so that the screen is directly facing the user; side angles will appear darkened. Remove the filter by gently lifting from one corner when you need full viewing access or to clean the screen and filter.

Recommendations

Clean the filter and screen with a soft, lint-free cloth and a mild screen-safe cleaner. Store the filter flat or in a protective sleeve when not in use to avoid scratches. Confirm compatibility with your device model and display size before purchase.
