3M Privacy Screen Protector PF21W for 21.5-Inch Monitor, 16:9, Reversible Matte/Glossy, Black

The 3M Privacy Screen Protector PF21W is a high-performance privacy filter designed for 21.5-inch widescreen monitors with a 16:9 aspect ratio. It utilizes advanced microlouver technology to narrow the viewing angle to 60 degrees (30 degrees left/right of center), ensuring that on-screen content is visible only to the user directly in front of the monitor. This makes it ideal for protecting sensitive information in open office environments, healthcare settings, or any public space.

Advantages

This privacy screen offers dual-sided functionality: a matte anti-glare side that reduces reflections and a glossy side for vibrant colors. It also reduces blue light by up to 35%, helping to minimize eye strain during extended use. The filter is reversible, allowing users to choose their preferred finish. Additionally, it provides scratch protection for the monitor surface.
