6. Negative Potential functon makes Ereada® distinctive
The natural voltage of healthy cells is about -70 millivolts. A big advantage of Ereada mats is that in addition to Negative ion emission layers, our Rich Brown Amethyst mats (Midsize and bigger) and some of Rich Brown and Gemstone Mini Mats are equipped with an advanced Negative Potential (N.P.) generation system called also Electrical Discharge of Negative Ions (E.D.N.I).
N.P. creates Electrostatic Field with 600 volts of Negative Potential converted at low speed into DC energy through the special Silver Fiber layer. It converts the mattress into a bath of anions into which you can sink your whole body.
Negative Potential function helps to support the potential and the natural electrical fields. It is the most powerful technology for inducing the negative ions in the amounts sufficient to alkalize.
N.P. function is available only in the Rich Brown Ereada® mats manufactured in Korea by Hyundai and in Richway BioMats ( E.D.N.I. ). Ereada® mats are the only ones with this function installed into the mini mats 20x32 and midsize mats 24x59 inch.
Negative Potential generation acts synergistically together with the Negative Ion function in maintaining the natural electrical potential level and providing multiple benefits known by practitioners and therapists. It is also important that N.P. is included into our mat for a small fraction of the cost of the special Negative Potential devices.
7. MORE THEN HOT STONE MATS. ADDITIONAL MAGNETISM and PHOTON functions.

COMBINATION OF NATURAL CRYSTALS METAPHYSICAL POWERS, LIGHT AND MAGNETISM ADOPTED BY ALTERNATIVE PRACTICES FOR AGES WITH SCIENTIFICALLY-BASED MODERN FAR INFRARED, ANION, N.P. (E.D.N.I.), PEMF, AND PHOTON TECHNIQUES BUILDS A BRIDGE BETWEEN EASTERN AND WESTERN TRADITIONS.
LAYERS AND TECHNOLOGIES
Purple Bio Magnetic PEMF Photon Ereada Amethyst Mat is a technology rich multi-layer system
Ereada® Mat is a unique mattress combining the benefits of the major natural elements of the Earth and Sun: Light, Crystal, Mountains, Air and Water.
The mat brings these vital natural powers into your home, office or massage studio.
Far InfraRed Light is the Sun’s spectrum most valuable radiant heat.
Deep Far InfraRed Rays (FIR) are amplified and structured in the Ereada® Mat through release of Amethyst "superconductor” power Crystal Rays absorbed during millions of years from the Earth and minerals.
Beneficial elements of Mountain Air and Waterfalls are Negative Ions which are delivered by the mat directly through the surface.
Red Light is the Sun’s non-heating 660 nm wavelength visible red light. It was very expensive to isolate only the red light from the full sun spectrum and special low level lasers were used. Nowdays after invention of the Light Emitting Diodes or LEDs it became possible to find a relatively cheap and generally recognized as safe source for monochromic red light. Original manufactured in Korea LEDs used in Ereada® mats emit 6-10 times more light than the similar LEDs used in the made in China mats. Red Light Phototherapy is widely used for its ability to rejuvenate the look of skin. It is also the main part of sun spectrum which does not come in sufficient amount to Northwestern States, New England and other North States during long winters
Static and Permanent Magnets concentrating the invisible but easily detectable power of Earth and metals have been used for their powers since ancient times. Nowadays the most advanced Magnetism techmology is the Extremely Very Low frequency Pulsed Magnetic Fields or PEMF supporting our efforts to awaken interior forces and boost our own natural wellness processes.
All key components of the natural powers are synergized in one unique application.
The main part of the Ereada® Mats 15-19 layers system is the semi precious crystal layer forming all the surface of the mat.
All mats come with the most advanced EMF free (less then 0.5-2 mG) electrical heating system with double shielded twisted titanium elements in double silicon and teflon insulation.
The heat is adjustable in the range between 86° and 158°F (30°-70°C) and is emitted in the form of Far- and Mid-InfraRed rays with 93% efficiency.
All mats have a built-in overheat protection layer as well as a uniform heating layer to keep users safe and provide a consistent warming experience.
When crystals become hot they start to generate Far InfraRed (FIR) crystal rays as well as Negative Ions.
To increase Far InfraRed Radiant Heat output Ereada® Amethyst FIR Mats are built with up to 30% more of natural untreated purple Amethyst crystals then any other Amethyst Mats of the same size.
The FIR rays generated by the heating layers are refracted and structured by crushed to small pieces natural amethyst (or in case of Ereada® Gemstone mats by a blend of amethyst, other crystals and bio ceramic micro spheres) to penetrate up to 6 inches (15 cm) deep.
These so called «Crystal Rays» come in the isolated most absorbable wave length range between 4 and 16 microns.
Permanent Static Magnets, Pulsation Magnetic Fields and Red Light Photonic functions make our mats truly unique yet affordable for home and professional use.

QUESTIONS & ANSWERSAsk a Question
What is mean when you said that the Purple Ereada is not equipped with direct current negative potential (N.P.)?
Thank you for your question.
All Ereada Amethyst mats generate negative ions by inner anion layers and crystals.
Brown mats have an additional silver fiber layer generating negative potential. It is a static negatively charged field surround the mat.
Purple and Gray mats do not have this function, but they feature pulsed electromagnetic fields (PEMF). Also, their controllers can release air ions.
How long do I use it for? Do I sleep on it over night or just lay on it for an hour or so?
For pleasure people use amethyst heating mats from one hour on high temperature to 12 hours on warm temperature daily. You can try and see what kind of sessions gives you the most benefits. We always recommend to start with the lowest or medium temperature levels 1-3 or 30-45°C for short periods of 20 - 30 minutes to see how your body reacts and then gradually increase the temperature and the length of the session over time.
You can certainly sleep on the mat over night but it is best to first get used to mat's hardness. Please, use only the lowest temperature settings (levels 1-3) for sleeping.
