EMF Shielding for CRT Computers & TVs

Best selection, great prices on Jitterbox, Magnetic Shields, Electric Shielding, Glare screens, Extention Cables


Important Notice: Computers and TVs produce at least two types of EMF radiation: Electric fields and Magnetic fields. While the scientific research to determine which of these two types is of greater concern is not yet conclusive, we do know that people can be sensitive to either. If you are not sure which field type you are most concerned about, you may want to consider using a combination approach. You can use just about any electric shielding device in combination with any magnetic shield for maximum protection. Any of these shields will work equally well with a monitor or TV, as long as the proper size is selected.

How to determine proper shield size

Monitor size is based on the diagonal of the monitor screen. Please note: the diagonal of the viewable area is smaller than the actual monitor size (by approximately one inch). Please use the dimensions below to help determine the suitable filter for your monitor:
