21.5" 16:9 Screen Protector for Monitors
This 21.5-inch 16:9 anti-blue-light glare filter fits standard, curved and touch widescreen monitors from brands including Dell, HP, Acer, ViewSonic, ASUS, AOC, Samsung, Sceptre and LG.

The accessory sits directly on the display surface without permanent adhesive.
Thermals, Noise and Power Draw
The passive filter adds no active cooling, so it produces zero fan noise and draws no power. Its eight-layer construction blocks 100% of hazardous UV light and filters the most hazardous HEV blue light in the 380-495nm range while also attenuating electromagnetic radiation. The anti-glare matte coating cuts strong-light reflections without noticeably dimming screen brightness.
Build Quality and Daily Use
A hardened oleophobic layer repels oil, sweat and water, allowing the surface to be wiped clean with a cloth. The protector installs on compatible 21.5-inch 16:9 panels and stays in place during regular adjustment of tilt or touch input. It is supplied new and backed by a 180-day replacement warranty from MUBUY INC.
