At ~£850 ex-VAT, Kensington’s 2‑way removable privacy filters are the kind of “nice to have” that becomes justifiable only if you’re dealing with sensitive work and you truly hate prying eyes. The 2‑way privacy angle is the main value: it helps stop shoulder-surfing in shared offices, open-plan workplaces, client-facing floors, or places where people inevitably wander behind you. If you’re equipping a handful of seats with sensitive data (finance, legal, procurement, health records, trade secrets), this can be a sensible risk-reduction move—especially if the removable design means IT or facilities can move/maintain screens without turning it into a constant pain.
That said, for most businesses this price is hard to defend. If your team is mostly in private, heads-down environments, or you’re looking for “privacy-ish” rather than real visual control from the side, you’ll likely get 80% of the benefit from cheaper alternatives and spend the rest on training, access controls, and proper screen lock policies. Also, if you’ve got a mix of monitor models or you don’t know you’ll standardise on this size, buying at this level can become expensive quickly. My honest take: buy it when privacy is genuinely a requirement and you’re standardising a set of monitor sizes; otherwise, it’s great kit, but at this cost it’s probably overkill.
