Far infrared heating technology is the most efficient way to turn electrical energy into heat. The far infrared waves produced in the BioSmart® Portable Quartz Far Infrared Heaters, travel quickly and are absorbed by water molecules in the air which keep the heat evenly distributed from floor to ceiling and wall to wall, providing soft, comfortable heat, that is never dry or irritating. The far infrared waves also penetrate and heat objects in the room directly, which in turn radiate heat back into your home. You will feel warmer with infrared heat since it's unique shorter wavelength makes it a more penetrating, direct heating source
