The 3M PF190W1B is a frameless blackout privacy filter that keeps your screen visible only from straight ahead. It uses microlouver technology to darken the display for anyone not directly in front, making it ideal for open offices or public spaces. The matte finish also cuts down on glare and reflections, which improves readability in bright lighting. Installation is simple with included attachment strips or sliding tabs. The filter is thin and lightweight, adding minimal bulk. One tradeoff is a slight reduction in brightness when viewing straight on, but it's a necessary compromise for privacy. The 25% discount makes this an attractive buy, especially compared to recent average prices.
At $54.29, the filter is 25% below its $72.87 original price. The 90-day average was $60.60 and the 180-day average was $57.46, so today's price is notably lower. It's a strong deal for a trusted brand.
It fits 19-inch widescreen monitors with a 16:10 aspect ratio and a viewing area of 18 15/16 inches diagonal. The filter measures 16 1/16 by 10 1/16 inches.
Yes, privacy filters typically reduce brightness by about 50-70% when viewed straight on, but the tradeoff is blocking side views completely.
It includes two attachment methods: adhesive strips for a permanent mount and sliding tabs for easy removal.
