Portable infrared sauna blanket suitable for health and beauty purpose for professional or leisure use. Excellent for detox, weightloss, or general health and relaxation. The blanket uses expensive carbon fibre heating wires which are imported from Japan. Carbon wires give off the highest levels of far infrared rays as opposed to cheaper wiring systems on the market. The far infrared emissions of the blanket have been tested and show high levels of far infrared ray (over 90%) within the 5-15 micron range. Please see the graph image from an International Testing Centre. The blanket is low voltage with 220V input and 36V dc output. Cheaper blankets on the market use high voltage control boxes that don't lower the voltage going into the blanket. We believe ours is the safest blanket on the market. Uses: Slimming,Beauty Purpose, Detoxification, Immunity, Chronic fatigue, Treatment of aches and pains (including arthritis), General fitness and Relaxation.
