Advanced Microlouver Privacy Technology
The 3M PF235W9B uses advanced microlouver technology to create effective "black out" privacy from anyone viewing your screen from the sides. Only users directly in front of the monitor can see the display content, while passersby see only a dark screen. This makes it ideal for protecting confidential information in shared offices, open-plan workspaces, coffee shops, airports, and any public environment where visual hacking is a concern.
Reversible Glossy/Matte Surface
Adapt to your working environment with the reversible design. The glossy side delivers pristine image clarity and vibrant colours for colour-critical work, while the matte side helps reduce reflections from overhead lighting and hides fingerprints for a cleaner appearance. Simply flip the filter to match your preference and lighting conditions.
Blue Light Protection for Eye Comfort
Extended screen time can lead to digital eye strain and disrupted sleep patterns. This privacy filter reduces 35% of blue light transmission from your display without distorting colours or affecting image quality, helping to reduce eye fatigue during long work sessions and potentially improving sleep quality when working late.
