3M PF235W9B

Overview

The 3M PF235W9B is a privacy filter designed for 23.5-inch widescreen monitors with a 16:9 aspect ratio. It protects sensitive on-screen information by limiting side viewing beyond 60 degrees, making the display appear dark and unreadable to anyone not sitting directly in front. This filter also reduces up to 35 percent of blue light, helping to ease eye strain during long hours of work. Its reversible design offers a choice between a glossy finish for vibrant colors and a matte finish to reduce glare and hide fingerprints, fitting well in shared offices, reception areas, and other busy environments.

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.
