Amazon.com Product Description
Providing basic protection for cost-conscious computer users, 3M's BF20XL is a standard, anti-glare filter for CRT computer monitors with 16- to 19-inch screens. The filter significantly reduces glare to help prevent glare-related eye strain and headaches. It also filters radiation, blocking up to 99.9 percent of a monitor's ELF/VLF E-field radiation (when properly grounded). The filter uses standard-tint, high-contrast glass and an easy-to-assemble flat-frame design. The company warrants the filter to be free from defects for at least one year.
