AI-generated summary
For £90.25 ex-VAT, this 3M privacy filter is the kind of “stop the hassle” purchase you make when you regularly work in shared offices, open-plan hotspots, or client rooms. The big win with 3M privacy films is reliability: they tend to fit well for their intended monitor size and do what they should—make the screen much harder to read off-angle without turning your workplace into a dim cave. If you’re handling anything sensitive (finance, HR, admin, even just internal data), it’s a sensible spend compared with constantly asking people to “move their chairs.”
That said, privacy filters aren’t magic and they can be annoying in the real world. Expect some trade-offs: slightly reduced brightness/clarity and, if you sit off-centre, the viewing angle can be a bit of a “sweet spot” thing. Also, if your monitor setup changes often (different desk, rotating displays, frequent device swaps), you’ll regret locking into a 25-inch portrait-specific filter. Who it’s best for: stable desks with a 25in portrait 16:9 monitor in a busy environment. Who should skip: anyone who needs maximum screen quality or who might replace/reposition monitors soon.
