3M Privacy Products
Featuring microlouver technology pioneered, designed and optimized by 3M to block side views so you see your screen clearly while people on either side see a vivid golden shield.

Privacy is the best policy
These days, screens are everywhere. And so are visual hackers. With the increase of mobile workers, open workspaces, and the migration of data to the cloud, computer screens can display private information virtually anywhere.

An unprotected screen can expose sensitive and private information, trade secrets and business plans. And the reality is, a visual hacker may only need one piece of valuable information to unlock a large-scale data breach.

A leader in screen privacy and protection
For more than 30 years, 3M has been advancing optical technology to deliver the gold standard in visual privacy. We remain a trusted global leader today—continuing to improve our technology, features and breadth of product.

Display and device technology continues to advance. So do we. Our privacy filters work simply and beautifully on most of today’s monitors to help protect your screens, and help keep the information on them private.

Behind the simplicity of our products is a powerful combination of optical science and sheer ingenuity you’ve come to expect from 3M. Rest assured, our products are inspected for quality defects, ensuring that you get authentic 3M Privacy Filters, with science applied to life.

Visual hacking: when information is visually captured without permission. But we’ve got you covered.

Gold standard in privacy
3M Gold Privacy Filters are perfectly suited for most of today’s high-resolution monitors. Maintain optical clarity while projecting a vivid golden shield to side views.

How privacy filters work
3M Privacy Filters block side views outside the 60 degree viewing angle, while providing a crisp, clear view to those directly in front of the screen.

Microlouver technology
A single microlouver is about as thin as a single strand of hair. There are thousands of microlouvers within one 3M Privacy Filter—all virtually undetectable by the human eye.

Attachment options
3M Gold Privacy Filters for Monitors attach with optically clear adhesive str限時活動優惠ips or easily removable slide mount tabs.

Find the right privacy filter for your screen

Step 1: Determine your screen type
Does your device have a raised bezel or a flat front glass screen?

Raised bezel: Screen with a raised frame around the edges.

Flat front glass: Screen with edge-to-edge glass without a raised frame.

Step 2: Measure your screen
For a raised bezel screen, measure the height (h) and width (w) of the screen's viewable area within the bezel.

For a flat front glass screen, measure the height (h) and width (w) of the entire glass display.

Step 3: Find your filter
Use the measurements to select the right sized filter for your device from the products listed below.

Best fit tip: If you don't see a filter that matches your measurements, select a filter that is larger yet closest to your measurements.
