From the manufacturer
Privacy is the best policy
These days, screens are everywhere. And so are visual hackers. With the increase of mobile workers, open workspace, 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 continue 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.
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.
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.
3M Gold Privacy Filters for Monitors attach with optically clear adhesive strips 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.

2 years ago I bought a Anti-glare screen shield from another company for my Macbook Retina as I did a lot of portable work and it worked wonders but they didn't stock any for 23" screens.
This is simply a bit of diffused plastic that is thick which reduces glare at the cost of readability and clear images. It's USELESS. I got a headache within 10mins of trying to use it.
see an image in my dropbox of what I mean. Overpriced garbage.
I'm using the 3M Privacy Filer PF 19 on a Dell LCD 19" monitor.
Things to Consider When You Purchase a Privacy Screen:
PRICE: I got out the catalog of the office supply chain that offers our institution a discount and checked the prices of privacy screens. Then I talked to our IT department and found out what they could offer my department. To say I had sticker shock is an understatement! One source was $100 more, our own IT department was $30 more than the screen I'm reviewing here and purchased from Amazon.
STYLE: I checked different privacy screens throughout our 8 story building and decided that there was no clear advantage to having a frame around the screen. It added to the bulk and quite a bit to the cost. The screens I looked at without frames were held in place by small tabs that came with the screen and attached to the monitor frame. No one I spoke to who used the frameless models reported any problems with the screen falling out, and a number of users said it stayed in place without the tabs (as I discovered later, mine does too).
EFFECTIVENESS: This privacy screen works very, very well. I've lost track of how many people have made me laugh by stopping and watching me stare at my screen as I'm intently reading something and asking me what's so fascinating about a monitor that's not on! I usually laugh, switch to a neutral web page and invite them over to "see" what I can see. The next question, after the "WOW", is where did I get it? I'm glad I kept the original packaging because I just pull it out and lend it to the person and usually I hear later that they've ordered one for their workstation(s).
As another reviewer noted, unless someone is standing right behind you or within approximately 20 degrees of the center of your monitor, they won't be able to see what's on your screen. And yes, if someone walks behind you, there is a point in their pass-by that they can see your screen, but it's brief, and unless they stop to focus, they quickly are out of the "I can see your screen" zone.
NICE FEATURES: There are two different "finishes", or looks to the screen. One side is a high gloss, the other matte. After using it both ways, I've decided that the gloss works better for my eyes. A second nice feature is a little half-circle, thumb-notch in the screen, at the top, that makes it easy and fast to pull the screen off the monitor if you want to share your screen with those around you. When I'm done sharing, I just pop it back into place. This is easy because as I mentioned before, the privacy screen stays in place wonderfully without the need for the tabs that are included.
The 3M Privacy Filter -3M PF19 is a product that not only would I purchase again, but did - 4 more of them for just our little department. I've always trusted 3M products, and this item has reinforced that trust.
Please make in more size, 3M! Would really like these for 21, 23, and 24 inch screens. Will not use other brands, as 3M has excellent service and will send you replacement sticky tabs, which I find invaluable. Do not hesitate to purchase this filter if you are wanting privacy.
