How long does the protection from EMF-Bioshield® last?
To be safe EMF-Bioshield® should be replaced after 24 months, regardless of CRT operating hours. Manufacturer research shows EMF-Bioshield® works perfectly until it loses its ability to resonate. It does not wear down gradually like a battery. This same research shows that some EMF-Bioshield® fail after 28 months, but most have functioned longer. Because there is usually some PEMF present even when CRTs are off, EMF-Bioshield® is resonating, generating counterphase waves and therefore in use whenever the bulbs are outside their original aluminum container.
