Kensington Anti-Glare and Blue Light Reduction Filter for 21.5" Monitors 21.5" Monitor Frameless display privacy filter

Product Overview

AI-generated summary

For £38.44 ex-VAT, Kensington’s 21.5" privacy/anti-glare + blue-light filter is a decent “meet compliance for half the budget” option—especially if you’re dealing with open-plan desks where people can glance sideways at sensitive screens. The anti-glare part is usually the most immediately noticeable benefit (less window/overhead reflection), and the privacy effect is handy if you want to reduce casual viewing without going all-in on replacement monitor hardware. In day-to-day work it’s the sort of thing that helps with privacy and comfort, not a miracle cure for eye strain.

That said, I wouldn’t buy these unless you’re happy trading a bit of brightness/clarity and you understand the viewing-angle limits. Privacy filters typically make the screen look darker from straight-on too, and colours can shift—painful for design work or anything colour-critical. They also need careful alignment on frameless screens; if your team is swapping monitors around or you don’t have someone willing to fit them properly, you’ll end up with complaints more than value.

**Who should buy:** office admins, customer support teams, finance teams in shared spaces, and anyone printing sensitive data from a regular 21.5" monitor who mainly wants reduced glances and better glare control. **Who should skip:** designers, photographers, anyone doing colour-sensitive work, and users who need maximum brightness and crispness.
