3M PF181C4B

Overview

The 3M PF181C4B is a privacy filter designed for 18.1-inch monitors with a 5:4 aspect ratio, providing an effective solution to protect sensitive information from side glances in shared environments. It uses microlouver technology to keep your screen visible only to you while darkening the view for anyone beyond a 60-degree angle. This filter also reduces blue light by about 35 percent, helping to ease eye strain during extended use, and supports touch interaction without compromising responsiveness.

Installation and setup

Setting up the privacy filter is straightforward and adaptable to your preferences. You can attach it semi-permanently using the included adhesive strips, which keep the filter firmly in place even when adjusting the screen. Alternatively, the slide mounts allow for quick removal at the end of the day, making it ideal for shared workstations or environments where privacy needs fluctuate. Both methods ensure the filter remains stable during use.

Ideal uses and environments

This privacy filter fits well in workplaces, classrooms, healthcare stations, and any shared spaces where protecting on-screen data is essential. It is particularly useful for professionals handling confidential information, such as financial data, patient records, or proprietary documents. The matte side helps reduce glare in brightly lit rooms or near windows, while the blue light reduction supports comfort during long hours of screen time.

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.
