3M PF215W9P Privacy Filter for 21.5in Portrait Monitor, 16:9
60° black-out privacy21.5" · 16:9Portrait orientationGlossy / matte reversible
The 3M PF215W9P is a black-out privacy filter for the 21.5" 16:9 monitor in portrait orientation: anyone looking from the side, outside a 60-degree viewing angle, sees a dark screen, while you keep a clear picture from the front. It is made for offices, reception and service desks, open-plan floors and anyone who works with personal, financial or customer data on screen.
3M makes this as a dedicated portrait version for a 21.5-inch 16:9 monitor mounted vertically, for example on a pivoting arm or in a dual-screen setup with one monitor turned upright. For the same monitor used in landscape, order the landscape model instead.
Both sides are usable: a glossy side for the crispest look and a matte side that cuts glare and fingerprints. 3M also states that the filter helps reduce blue light without distorting the natural colours of the display. The filter is made in the USA, TAA compliant and 100% hand-inspected.
Before you order: Portrait version for a 21.5" 16:9 monitor used vertically. Measure the viewable area inside the bezel and match both diagonal and aspect ratio.
What's in the Box
- 1 × 3M PF215W9P privacy filter
- 3M does not list the attachment parts supplied with this model and notes that some attachment parts are not included with every filter; adhesive strips and slide-mount tabs are available from 3M as attachment parts
What It Means in Practice
- A colleague beside your desk, a visitor at reception or a passenger next to you in a shared space sees a dark screen; you see the normal image from the front.
- Turn the filter to the glossy side for a brighter, sharper look, or to the matte side if overhead lights or windows reflect on the screen.
- Take the filter off before you clean the monitor; clean the filter with a soft lint-free cloth and an ammonia-free glass cleaner, as 3M recommends.
- 3M builds the filter to withstand hundreds of cleanings, so it is meant to stay on the monitor for everyday use, not as a temporary cover.
What Will Not Work
- A monitor of a different size or aspect ratio: a 21.5" 16:10 screen, for example, needs a different 3M model.
- Frameless monitors with flat front glass: for those, 3M makes Full Screen (E/EM) filters designed to span the glass edge to edge.
- The same monitor used in landscape orientation: this is the portrait version.
- Someone standing directly behind you: the black-out works for side views outside the 60-degree angle, not for someone looking over your shoulder from straight behind.
- Touchscreen use: 3M does not state compatibility for this model, so ask us before ordering for such a display.
Key Features
60-degree black-out privacy
Outside a 60-degree viewing angle the screen turns dark for side viewers, so on-screen data stays between you and the monitor.
Glossy or matte, your choice
Reversible filter: glossy side for clarity, matte side to reduce glare and fingerprints in bright rooms.
Blue light reduction
3M states the filter helps reduce blue light without distorting the natural colour of the display.
Portrait orientation
Dedicated version for a monitor mounted vertically, so the privacy effect works the way the screen is used.

Frequently Asked Questions
How do I measure my screen for the right filter?
First check the monitor type. With a raised bezel, 3M says to measure the height and width of the viewable area inside the bezel; with flat front glass, measure the entire glass edge to edge. Then match the diagonal and the aspect ratio to the 3M model.
Can I remove it for presentations or screen sharing?
Yes. The filter attaches with removable attachment parts, so it can be taken off and refitted. 3M does not list which parts come with this model; replacement adhesive strips and slide-mount tabs are available from 3M.
Will it change the colours on my screen?
From the front you keep the normal image. 3M states that the blue-light reduction does not distort the natural colour of the display; use the glossy side for the crispest look or the matte side to reduce reflections.
Singular Expert Insight · Buyer's Guide
Getting the size right is most of the job: the filter must match the diagonal, the aspect ratio and the monitor type (raised bezel or frameless glass), because that decides which 3M family fits. Bezel filters are the classic choice for monitors with a visible frame around the picture. For other sizes and models, see our
privacy filters and screen protectors.
