Designed for the Lenovo Z13 with a 33.8 cm (13.3") 16:10 display, this frameless privacy filter (MPN 4XJ1U03942) limits side viewing to approximately 30° while maintaining 85% light transmission for clear on-axis viewing. The Premium Clarity Privacy Filter balances strong privacy protection with bright, accurate display clarity, and includes an antimicrobial coating. It is intended for professionals who need to protect on-screen data in public spaces or during travel.

Advantages

The frameless design preserves the original look of the laptop while the filter reduces side-angle visibility to protect sensitive information.

The 85% brightness transmission maintains image clarity for typical office and mobile work. A custom fit for the Lenovo Z13 ensures full coverage of the 16:10 display.
