The 3M PF181C4B is a privacy filter designed for 18.1-inch monitors that use the traditional 5:4 aspect ratio. It offers a straightforward way to shield sensitive on-screen information in workplaces, classrooms, healthcare stations, or any shared environment where you need to keep prying eyes away. When the filter is in place, microlouver technology lets you see your data clearly while anyone viewing from the side beyond about 60 degrees sees only a dark screen.
Everyday usability is at the heart of this filter. You can flip it to suit your surroundings: use the glossy side when you want vivid clarity or switch to the matte surface when you need to cut reflections and hide fingerprints. The matte side can be especially helpful under bright overhead lighting or in offices with large windows, where screen glare is a regular distraction.
The filter also reduces blue light by about 35 percent, which may help lessen eye strain during long stretches of spreadsheet work, coding sessions, or patient chart reviews. Because the construction supports touch interaction, you can keep the filter on touch-enabled monitors without losing tap, swipe, or pinch functionality.
Installation is quick. Choose the included adhesive strips for a semi-permanent fit or slide mounts if you prefer to remove the filter at the end of the day. Either method keeps the filter stable even when screens are adjusted or shared. A durable build and easy-to-clean surfaces withstand frequent handling, and each unit is hand inspected by 3M for consistent quality.
