More About the EMP Shield

EMP Shield offers the fastest over-voltage protection on the market today. Each of our models are very exquisitely and robustly designed to meet and exceed current Mil-Spec standards. Electrical surges move along your household wiring very quickly, however our EMP Shield is capable of shunting away overvoltage before the energy can move farther than 12 inches from your breaker panel.

EMP Shield Home and Small Business models are designed to protect your assets while they are connected to the Grid or Homestead’s power supply. Each of these models will start shunting (removing) overvoltage in less than one nanosecond.  That is less than one billionth of a second.  Each EMP Shield utilizes three specialized distinct and proprietary overvoltage protection technologies to protect your home and assets from any overvoltage, including Lightning, Coronal Mass Ejection (CME) and Electromagnetic Pulse (EMP). We believe EMP Shield products will be pivotal in in ensuring national defense and national security should a high altitude nuclear weapon be detonated producing an incredibly dangerous electromagnetic pulse. 


“Whole House Electrical Surge and EMP Protection”


EMP Shield has been rigorously tested at the Keystone compliance facility which is a federally approved facility that is used to conduct many of today’s most advanced and rigorous technological tests. Out testing and evaluations conducted at the facility were documented in depth to show the true ability and durability of the EMP Shield. The testing results derived from Keystone compliance testing facility highlights EMP Shields true strength and capability. Below you will find the complete Keystone Compliance testing results of the EMP Shield.

Trusted by the Department of Homeland Security

EMP Shield is currently working with the Department of Homeland Security and the Department of Defense to Strengthen and Harden our Military Bases, Facilities and Assets not only within the continental United States, but around the World.  Why should your home or vehicle be any less protected?

Far Surpassing DOD Standards

DOD standards require E1 spikes begin shunting at 20 nanoseconds. EMP Shield does it in less than 10 nanoseconds, while some models can begin shunting overvoltage in less than 1 nanosecond. A nanosecond is fast, but our advanced proprietary EMP Shield technology is faster!
