Filtro privacy 3M BP140W9B 14" lucido/opaco 85 % trasmittanza luminosa

The 3M Bright Screen Privacy Filter BP140W9B is a frameless privacy screen designed for 14-inch laptops. It combines a glossy/matt finish with 85% light transmission and a 60° viewing-angle limitation to reduce side visibility and protect on-screen information in public or shared environments.

Advantages

Its frameless design keeps the laptop profile slim and unobtrusive, and the surface finish balances reduced reflections with screen legibility. The filter is simple to apply and remove, allowing flexible use when privacy is or is not required.

Suitable for

• Working in public places such as cafés, airports or co-working spaces
• Using laptops on trains, buses or other shared transport
• Handling confidential documents or sensitive information in open-plan offices
• Mobile professionals who need occasional screen privacy

How to use
