The 3M BP133W9B frameless privacy filter protects on-screen information on 33.8 cm (13.3") laptops while maintaining 85% light transmission for clear viewing by the device user. Designed to reduce side-angle visibility to approximately 60 degrees, this privacy filter helps prevent visual hacking in public spaces and reduces screen glare. It is a slim, easy-to-apply accessory from 3M suited for users who need on-the-go data protection without significantly affecting screen brightness.

Advantages
