3M PF315W9B

Overview

The 3M PF315W9B is a privacy filter designed specifically for 31.5-inch widescreen monitors, offering a practical solution to protect sensitive information from prying eyes. Using advanced microlouver technology, it limits side viewing angles to about 60 degrees, ensuring that only the person directly in front of the screen sees clear content while others see a darkened display. This filter fits both flat and gently curved monitors and includes options for permanent or removable installation, making it adaptable to various work environments.

• Built-in blue light reduction to enhance eye comfort during extended screen use without altering color accuracy
• Flexible construction that fits flush on flat or gently curved monitors and remains stable when tilting or pivoting the screen
• Two installation options: adhesive strips for a permanent fit or slide mounts for easy removal and reattachment
• Durable materials that withstand routine cleaning without compromising clarity, ideal for high-traffic or shared workstations

Installation and setup

Setting up the privacy filter is straightforward and flexible to suit your preferences. The included adhesive strips provide a secure, permanent attachment for users who want a fixed solution. Alternatively, the slide mounts allow you to easily remove and reattach the filter as needed, which is convenient for shared workstations or when cleaning the screen. The filter’s flexible design ensures it sits flush against the monitor surface, maintaining a neat appearance and consistent privacy protection even when the screen is tilted or swiveled.

Ideal uses and environments

This privacy filter is well suited for environments where sensitive information is frequently displayed, such as offices, healthcare facilities, reception areas, and public spaces like libraries or coffee shops. It helps reduce distractions and protects data from unintended viewers, making it a strong choice for professionals who handle confidential documents or work in open-plan settings. The blue light reduction feature also supports users who spend long hours in front of the screen, including designers, analysts, and administrative staff.

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.
