3M PF170C4B

Overview

The 3M PF170C4B is a privacy filter designed for 17-inch standard monitors with a 5:4 aspect ratio. It protects your screen content from side views beyond a 60-degree angle, making it an excellent choice for open offices, public spaces, or any environment where sensitive information needs to stay private. The filter features microlouver technology that darkens the display when viewed from the side, ensuring only the user directly in front of the screen can see the content clearly.

This filter is reversible, offering a glossy side for vibrant and sharp visuals and a matte side that reduces glare and minimizes fingerprints. It also helps reduce blue light exposure, which can ease eye strain during long periods of use. Installation is simple, with options to attach using adhesive strips or slide mounts, allowing easy removal for collaboration or cleaning.

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.
