EMF Protection

Electromagnetic Spectrum

Electromagnetic fields (EMFs) are present everywhere in the nature. Light is its most familiar form though most part of EMFs is invisible to the human eye.

Electric and magnetic fields spectrum extends from static electric and magnetic fields, through radio frequency and InfraRed radiation, to X-rays.

They include Sun light, electricity in different forms, Earth magnetism and many micro sources of energy including our bodies, organs and cells.

It is important to understand the difference between the healing electromagnetic fields and harmful EMFs which can cause damage to human bodies.

Dangerous EMFs

There are a lot of natural harmful EMFs as UV light in high dozes, Gamma- or X-rays radiation. The hazardous manmade electromagnetic fields also surround us. These fields are generated by electrical wiring in our buildings, electric tools, kitchen appliances, cell phones, computers, telecommunications and other devices. They can be distinguished by High Frequencies and High Intensity.


Some studies have shown a link between cumulative EMF exposures and increased rates of diseases, depression and mind disorders.

MediCrystal® Mat construction provides Far InfraRed heating without any harmful electromagnetic fields emissions.

Full protection from harmful EMF is provided by the double silicon insulation and shielding of heating elements with the special wires catching and eliminating EMFs. The EMI (electro magnetic waves interceptor) layers with copper, charcoal fiber and aluminum foil control the remaining EMF on almost zero level.

Heavy Amethyst layer is also known for interception of EMFs generated by electronic devices in the space around. Negative Ions emitted by the MediCrystal® Mat may help to neutralize the positive ionization of harmful EMF.

The EMFs of mats are controlled on the safest zero level. The measurement showed that even during the electric power spikes the magnetic fields intensity was less then 0.2 milliGauss (mG) on low heating and less then 0.6 mG on the highest heating level, which is even less then a typical in home background (0.5-4 mG), and is considered generally safe for sleeping (less then 1 mG is recommended).

For comparison the users of the devices such as laptops are subject to EMF exposure in the range of 2 to 20 mG, electric blankets 5 to 30 mG, hair dryers 10 to 70 mG, and an in floor electrical heating system EMFs can reach even more then 100 mG.

The MediCrystal® Mat different frequencies EMFs average levels less then 10 dB are far below then the standards for safety established by FCC for USA and CE for Europe (40-60 dB).

The manufacturing facilities of MediCrystal® mats passed CE and FCC certification for Elecrtrical and Electro Magnetic Safety and Compatibility.

Safety and absence of harmful electromagnetic fields is confirmed by EMF tests in FCC registered Laboratory.
