Working in public and worried about prying eyes? This 3M Bright Screen Privacy Filter keeps your screen private. It's made specifically for Dell multi-line laptops with a 13-inch, 3:2 aspect ratio display (model BPNDE005). The filter uses 3M's Advanced Nanolouver tech – it lets you see the screen clearly straight on, but from side angles beyond 60 degrees, the screen looks black. It's up to 25% brighter than some other black privacy filters, so your display doesn't get too dim. It also helps reduce blue light without messing up colors. Installation is easy with the included COMPLY Flip Attach (lets you flip it up for sharing) and adhesive strips to keep it secure. The surface is glossy on one side, matte on the other, so you can choose based on your glare preference. It's a simple way to protect sensitive info at coffee shops, offices, or on planes. Just stick it on and work with peace of mind.
