Virtually all particles in the air have a positive charge. Therefore, negative ions and the positively charged particles magnetically attract to one another. When there is a high enough concentration of negative ions in the air, they will attract to floating particles in very large numbers. This causes the particle to become too heavy to remain airborne. As a result, the particle will fall out of the air, preventing it from being inhaled into the respiratory tract where it can trigger breathing and health problems.
The ionized particle will then be collected by normal cleaning activities, such as vacuuming or dusting. If the particle happens to be kicked back up into the air again, it will be ionized, and quickly settled out of the air once again.
In nature, processes such as sunlight, lightening, waves from the ocean, and waterfalls generate negative ions. The "Concrete Jungles" that many people live in minimize the natural production of negative ions by disrupting the delicate electrical balance between the atmosphere and the earth. Our ionic air purifiers recreate them with electrode tubes to electrically produce negative ions in a safe and effective process. This method produces a density that is many times higher than the negative ion level found even at Niagara Falls, the highest natural producer of negative ions and one of the healthiest environments in the world.
