COMPARE
The differences that matter.
Compare device shields by what they measure, how they record, and what they cannot tell you.

| Limitations | Blushield markets this as a "harmonizing" or "scalar field" device: it does not claim to physically block, attenuate or reduce measured EMF the way shielding fabric, paint or a Faraday enclosure does, so it has no comparable dB attenuation figure and cannot be evaluated the same way. EMF Practical has not independently tested its claimed effects. Coverage and exposure-level guidance above is the manufacturer's own positioning, not a measured result. | Blushield markets this as a "harmonizing" or "scalar field" device: it does not claim to physically block, attenuate or reduce measured EMF the way shielding fabric, paint or a Faraday enclosure does, so it has no comparable dB attenuation figure and cannot be evaluated the same way.
