The 3M PF400L privacy filter fits 14"–16" CRTs and 15" LCD monitors with a 4:3 aspect ratio. Its flat framed design uses microlouver technology to keep on-screen data visible only to the person directly in front of the monitor while reducing glare and preserving image clarity.

Advantages

This framed display privacy filter reduces glare by up to 95% and transmits approximately 38% of light, maintaining bright graphics and improved contrast through standard tint glass. It prevents static and dust build-up, blocks up to 99.9% of ELF/VLF electric field radiation when properly grounded, and preserves screen detail without blurring or distorting images.

How to use

Attach the PF400L to the monitor using the framed mounting method provided by 3M, aligning the filter with the screen edges and securing it according to the manufacturer’s instructions. Position the monitor so typical users face it directly; the microlouvers allow only front-facing viewers to see the screen content clearly while others see a darkened display.

Recommendations

To maintain optimal privacy and protection, clean the filter with a soft cloth and glass cleaner, avoid abrasive materials, and ensure proper grounding if you require ELF/VLF field attenuation. Use the filter on compatible 4:3 monitors and check fit for 15" LCDs or 14"–16" CRTs before installation.
