3M PF133W9B

Overview

The 3M PF133W9B is a privacy filter designed specifically for 13.3-inch widescreen laptops with a 16:9 aspect ratio. It uses advanced microlouver technology to narrow the viewing angle, ensuring that only the person directly in front of the screen can see the content clearly. This makes it an excellent choice for travelers, remote workers, and anyone working in open or public spaces who needs to protect sensitive information from prying eyes. The filter is reversible, offering a glossy side for sharp color accuracy and a matte side to reduce glare, while also cutting blue light transmission by up to 35 percent to ease eye strain during extended use.

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.
