Overview

The 3M HC215W9B is a high clarity privacy filter designed specifically for 21.5-inch widescreen monitors with a 16:9 aspect ratio. It protects sensitive information by blocking side views beyond a 60-degree angle, ensuring that only the person directly in front of the screen can see the content clearly. This filter enhances your viewing experience by delivering nearly 20 percent more clarity than standard black privacy screens while reducing blue light transmission by about 35 percent to ease eye strain during long hours of use.

It works effectively in environments where privacy is critical, including shared offices, clinics, classrooms, and public areas like coffee shops. The combination of enhanced clarity and blue light reduction also makes it a strong choice for users who spend extended periods in front of their monitors and want to protect their eyes while maintaining image quality.

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.
