The heating principle of far infrared rays is different from that of ordinary wires. Carbon fiber material replaces the traditional metal heating wire. After high temperature carbonization and surface treatment, it has the properties of oxidation resistance, light weight, low temperature coefficient of resistance and stable electrical properties. Translating into Mandarin is light, a little power-saving and safe. But its health care function, like those things in Yu Pei, should be negligible.
Finally, let's talk about the feelings after personal application. Ordinary electric blankets are bumpy because of metal pipes. People who require very high softness and smoothness of the bed may not be used to it. Far infrared has no electron tube. My body has no feeling of fever.
