3M Privacy Filter for 13.3" Widescreen Laptop with COMPLY Attachment System

The 3M PF133W9B is a privacy filter built for 13.3-inch laptops that use a 16:9 widescreen format. It relies on microlouver technology that narrows the viewing angle so only the person sitting directly in front of the display can see the content. Anyone seated to the side sees a dark, obscured screen, which makes this filter a practical tool for travelers, remote workers, and anyone who spends time in open offices or public spaces.

The filter is reversible. One side has a glossy surface that preserves color accuracy and sharp detail, which is useful when you are editing photos or watching videos. The opposite side features a matte finish that scatters reflections to cut down on glare under bright lights or near windows. On either side, the filter can lower blue light emission by up to 35 percent, helping to reduce eye fatigue during long work sessions.

3M includes the COMPLY attachment system, a pivoting mechanism that secures the filter along the top edge of the laptop. Flip the panel down when you need privacy, then lift it up instantly to share your screen in a meeting. The mount stays in place through daily opening and closing of the laptop lid and removes cleanly if you move to another device.

In addition to privacy, the filter provides a thin shield that helps protect the screen from scratches, smudges, and general wear. Because it is precisely cut for 13.3-inch widescreen models, installation is straightforward with no trimming required.
