3M Anti-Glare Filter for 21.5" Widescreen Monitor

The 3M AG215W9B is an anti-glare filter made specifically for 21.5-inch widescreen monitors with a 16:9 aspect ratio. It helps reduce glare and reflections that can make your screen hard to see, especially in brightly lit rooms or near windows. This makes it easier to work for longer periods without straining your eyes.

Applying the filter is straightforward thanks to the included adhesive strips and slide mount tabs, which let you attach or remove it quickly whenever you need. The matte finish not only cuts down on fingerprints and smudges but also offers protection against dust and scratches, keeping your screen cleaner and clearer over time. It works well with most touchscreen monitors, so you won’t lose any touch functionality while improving your viewing comfort.

This filter is a practical choice for office workers, students, or anyone who spends a lot of time in front of a 21.5-inch widescreen monitor and wants to reduce eye fatigue caused by glare. It’s also useful in environments where lighting conditions change throughout the day, helping maintain consistent screen visibility.
