Orion Lights - Salt of the Earth

If I got this through my thick skull, Orion Lights are made from salt crystals. And when heated (by the included internal halogen lamp), they release a wave of negative ions, which have the positive effect of attracting "pollutants such as bacteria, pollen, dust and smoke". The combined weight of these now co-joined ions makes them too heavy to remain air-borne and they drop to the floor, away from lungs. Why is this important? Well, it has been estimated that poor indoor air quality in Australia costs the economy up to $12 billion AUD per year. The colours of the lights are said to be "formed naturally by the fusion of potassium, magnesium and other minerals." Pretty sure I got all that right! ::Orion Lights
