3M Anti-Glare Filter for 13.3" Widescreen Laptop

The 3M AG133W9B is an anti-glare filter created for laptops that use a 13.3 inch widescreen display with a 16:9 aspect ratio. It improves screen visibility by cutting harsh reflections, making it easier to work under bright office lights or next to a window on a sunny day.

A matte surface scatters reflected light and reduces mirror-like glare, so you see your spreadsheet or streaming video instead of your own reflection. The same surface also helps hide fingerprints and smudges, keeping the display looking clean between wipe-downs.

The filter is thin, frameless, and light in weight, so it preserves the slim profile of modern laptops and allows the lid to close normally. Because it works with most touch-enabled screens, taps, swipes, and gestures remain precise and responsive.

In addition to glare control, the filter acts as a protective layer that helps shield the display from dust and small scratches. This added durability is useful for students moving between classes, professionals commuting with a laptop in a bag, or anyone who sets up in shared workspaces.

Installation is straightforward. Use the included adhesive strips for a secure fit that stays in place, or choose the slide mounts if you prefer to remove the filter during presentations or when cleaning the screen. Both methods take only a few minutes and require no special tools.
