Ions are invisible particles, either molecules or atoms, which bear an electric charge. Atoms, for instance, consist of an atomic nucleus that contains neutral neutrons and positively charged protons, as well as orbiting electrons that are negatively charged. When an atom is in a neutral condition, the number of protons (+) and electrons (-) is equal. When the number of protons and electrons is not the same, the particle becomes an ion that is either positively or negatively charged.
Positive Ion (Cation): an atom (or molecule) that has lost one or more electrons due to a high-energy impact. Natural forces that generate positive ions include the decay of radioactive minerals, radon gas, forest fires, lightning and ultraviolet rays.
Negative Ion (Anion): an atom (or molecule) that has gained one or more extra negatively charged electrons. Negative ions are naturally generated by evaporating water, ocean surf, waterfalls and ionic minerals such as Tourmaline.
There are also certain minerals that emit Negative Ions for example Tourmaline and Germanium.
Negative Ions can be artificially generated by electrical devices such as Air Ionisers which use an external power source (electricity) to generate large quantities of Negative Ions. Our USB Personal Air Purifier Ioniser and our 8 in 1 Room Air Purifier Ioniser both use electricity to generate Negative Ions.
Virtually all particles in the air have a positive charge, while negative ions have a negative charge. In which case, negative ions and 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 large numbers. This causes the particle to become too heavy to remain airborne. As a result, the particle will fall out of the air, and will then be collected by normal cleaning activities, such as vacuuming or dusting.
In nature, negative ions are generated by processes such as sunlight, lightening, waves from the ocean, and from waterfalls. "Concrete Jungles" minimize the natural production of negative ions by disrupting the delicate electrical balance between the atmosphere and the earth. Ioniser/ionic air purifiers recreate them with electrode pins ("needlepoints") to electrically produce negative ions.
The most popular product we stock is the Ionic Balance Band (worn on the wrist) which uses Tourmaline to naturally emit Negative Ions. We carry a range of ionic products suitable for humans and pets.
Our USB Personal Air Purifier Ioniser is ideal for travel and can be plugged into any USB socket. Our 8 in 1 Room Air Purifier Ioniser can be used in the home or office and also comes with a 12v adaptor for use in the car.
Ancient peoples recognized that the air is "electric" so to speak, but it is thought that the formal study of ions did not begin until fairly recently. In 1899, two German scientists, Elster and Geitel, discovered that there are particles in the atmosphere that carry electricity. These particles were later named "air ions" by the British scientist Faraday. The word "ion" was taken from the Greek language, in which it means to "go" or "wander about."
To date over 5000 studies have been conducted on Negative Ions. Many of these are available online.
