3M AG240W9B

Overview

The 3M AG240W9B is an anti-glare filter designed specifically for 24-inch monitors with a 16:9 aspect ratio. It reduces distracting reflections caused by overhead lighting and sunlight, allowing you to view screen details comfortably without squinting or repositioning your display. This filter is ideal for bright environments such as open offices, home workstations, and classrooms where controlling ambient light is difficult.

Its matte surface not only diffuses glare but also minimizes fingerprints, making it especially useful for touch-enabled monitors. The frameless, lightweight sheet protects your screen from dust and minor scratches, and it can be easily cleaned with a quick wipe. Installation is flexible, offering both adhesive strips for a semi-permanent mount and slide mounts for easy removal.

Ideal uses and environments

This anti-glare filter works well in environments where bright lighting cannot be controlled, such as open-plan offices, classrooms, and home workspaces near windows. It is a strong choice for professionals who spend long hours in front of their screens, including graphic designers, coders, and financial analysts, as it reduces eye strain without compromising color accuracy. The filter also suits casual users who want to enjoy streaming or gaming in well-lit rooms without glare interference.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
