3M PF215W9B display privacy filter 54.6 cm (21.5") Monitor Frameless display privacy filter

Product Overview

AI-generated summary

If you’re worried about shoulder-surfing on an open-plan floor, a 3M privacy filter is one of the more reliable “set it and forget it” options. The PF215W9B is a good fit for anyone using a 21.5" frameless-style monitor in shared spaces (call centres, trading desks, admin teams with sensitive data). You don’t need to be especially technical—once it’s aligned, it behaves like proper screen protection: reduces casual viewing from the sides without you constantly fiddling with settings.

That said, £77.76 ex-VAT isn’t cheap, and privacy filters always come with a trade-off: your screen will look a bit dimmer/less “open” than it does without the filter. If your workspace is private, or your priority is colour/brightness (design, video work), it may feel like you’re paying for privacy at the cost of display quality. Also worth considering if you’ve got frequent monitor swaps—filters are a bit of a hassle to move between different sizes/frames. Overall: buy it if you genuinely need side-view privacy and you’ve got a stable 21.5" setup; think twice if this is mostly for “nice-to-have” security.
