Air Ioniser
An air ionizer (or negative ion generator) is a device that uses high voltage to ionise (electrically charge) air molecules. Negative ions, or anions, are particles with one or more extra electrons, conferring a net negative charge to the particle. Cations are positive ions missing one or more electrons, resulting in a net positive charge. Most commercial air purifiers are designed to generate negative ions. Another type of air ioniser is the ESD ioniser (balanced ion generator) used to neutralise static charge.
Russian scientist and inventor Alexander Chizhevsky produced the so called Chizhevsky Chandelier around 1918. This was the first modern air ioniser.

Famous quotes containing the word air:
“His hope is treacherous only whose love dies
With beauty, which is varying every hour;
But, in chaste hearts uninfluenced by the power
Of outward change, there blooms a deathless flower,
That breathes on earth the air of paradise.”
—Michelangelo Buonarroti (1474–1564)
