Consumer EMP shields and surge protectors cannot stop an E1 pulse

A growing market of consumer "EMP protection" devices — surge protectors, whole-home EMP shields, Faraday bags — is sold to preparedness-minded consumers with claims of HEMP protection. Most of these devices are essentially MOV (metal oxide varistor) surge protectors or SPDs (surge protective devices) that clamp at microsecond timescales. The E1 component of a HEMP event rises in 5 nanoseconds — roughly 1,000x faster than these devices can respond. Consumers spend $200-2,000 on devices that provide a false sense of security. When they rely on these devices in an actual EMP scenario — whether from a HEMP, a non-nuclear EMP weapon, or a severe geomagnetic storm — their electronics are destroyed anyway. Worse, the false confidence discourages people from taking actually effective measures like maintaining analog backups, storing spare electronics in proper military-spec shielded enclosures, or hardening their homes' electrical entry points with proper waveguide-below-cutoff techniques. This persists because there is no FTC enforcement against EMP protection claims — the event has never occurred, so no consumer can prove the product failed. Companies cite MIL-STD-188-125 compliance without undergoing actual military testing. The prepper market is driven by fear, not engineering literacy, and Amazon's review system cannot distinguish between "this arrived in nice packaging" and "this would survive 50 kV/m E1."
