How to Choose a Privacy Screen Protector
There are three key things to confirm when shopping for a privacy screen.
1. Match the Screen Size and Attachment Method
Privacy screens must match your laptop’s exact screen size (e.g., 13.3", 14", 15.6") and aspect ratio (16:9, 16:10, or 3:2). A mismatch leaves gaps that defeat the purpose. For attachment, the main options are: tab/slide (slips into the bezel β easy and widely available), magnetic (snaps on and off instantly β best for frequent removal), and adhesive (most secure β not ideal if you remove it often).
2. Matte vs. Glossy Surface
If you frequently work in cafes, on trains, or near windows, a matte (anti-glare) finish prevents reflections and keeps the screen readable. For color-sensitive design or photo editing work, a glossy finish preserves color richness. For general remote work, matte is the safer choice.
3. Blue Light Cut Combo
Some privacy screens combine anti-peep protection with blue light filtering, giving you two benefits in one product. If you spend many hours at a screen and experience eye strain, choosing a model that cuts 30β35% of blue light is worthwhile.

1. Elecom EF-PFNS2 β Our Top Pick
Elecom is one of Japan’s most trusted peripheral brands, and the EF-PFNS2 is their go-to privacy screen for everyday business use. The matte anti-glare surface cuts reflections from overhead lights and windows without washing out the image. The tab attachment fits securely into the bezel and can be removed quickly when you’re back at your desk. With a wide range of sizes from 13.3" to 16", it covers virtually every mainstream laptop. Great quality at a reasonable price β the easy choice for most people.
2. 3M Privacy Filter PF Series β Best for Enterprise Use
3M essentially invented the modern privacy filter, and the PF series remains the benchmark for anti-peep performance. Their proprietary micro-louver technology delivers industry-leading side-angle blackout, which is why the PF series is standard-issue in many corporate security policies. It’s available in both tab and adhesive versions across matte and glossy finishes. It costs more than alternatives, but for professionals handling sensitive data, the combination of brand reputation and proven performance is worth the premium.
3. Kensington MagPro β Best for Easy On/Off
Kensington’s magnetic attachment is a game-changer for users who want to remove the filter regularly. Magnets embedded in the filter snap to a thin strip you attach to your laptop bezel, making removal and reattachment effortless. It also includes blue light filtering, making it the most versatile pick for long workday comfort. Compatible with thin-bezel laptops like the MacBook Pro and Dell XPS that don’t accommodate tab-style filters well.
4. Sanwa Supply LCD-PF Series β Best for Desktop Monitors
Sanwa Supply is a Japanese peripheral veteran with a particularly wide lineup of privacy screens covering not just laptops but also large desktop monitors up to 27". If you need privacy protection for an office desktop display, this is one of the few consumer brands offering that. The anti-glare coating prevents reflections on large displays, and the tab attachment keeps things simple. Cost-effective for bulk office purchases.
5. Befon Privacy Filter β Best Budget Pick
At $15β$30, Befon’s privacy screen packs an anti-glare matte surface and blue light filtering into an affordable package. The tab attachment is easy to use, and for occasional use in cafes or co-working spaces, the anti-peep performance is perfectly adequate. If you’re trying a privacy screen for the first time and aren’t sure you’ll use it every day, Befon is the lowest-risk way to find out.
Summary
If you can only pick one, go with the Elecom EF-PFNS2 β it nails the balance of price, performance, and ease of use for everyday remote and office workers. If you remove the filter constantly, upgrade to the Kensington MagPro for its magnetic snap-on convenience and blue light protection. For sensitive enterprise work, 3M’s PF series is the proven, policy-compliant choice. Need coverage for a desktop monitor? Sanwa Supply LCD-PF is your best option.
