Blushield is a revolutionary form of EMF protection that produces coherent frequencies within the human responsive range, based on nature-mimicking mathematical algorithms. It emits frequencies using the same power sources as manmade devices, which creates active, powerful fields. It is essentially “loud” enough to compete against the biologically incoherent non-native EMF fields. That way, it vastly outperforms the protective devices with weak, passive fields that don’t use a power source (such as stickers, pyramids and pendants). Shipments require signature for delivery.
