An air ioniser (or negative ion generator or Chizhevsky's chandelier) 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.
For seasonal affective disorder (SAD), a randomized controlled trial (RCT) comparing high (4.5x10 14 ions/second) and low (1.7x10 11 ions/second) flow rate negative air ionization with bright light therapy found that the post-treatment improvement percentage was 57.1% for bright light, 47.9% for high-density ions and 22.7% for low-density ions.

Most ionizers produce less than 0.05 ppm of ozone, an industrial safety standard. There are two major subdivisions: the fanless ionizer and fan-based ionizer. Fanless ionizers are noiseless and use little power, but are less efficient at air purification. Fan-based ionizers clean and distribute air much faster.
Researchers using high-tech air monitoring equipment rolled through an industrialized stretch of southeast Louisiana in mobile labs and found levels of a carcinogen in concentrations as much as 20 ...
Negative air ions (NAI) are important air component, generally referring to the collections of negatively charged single gas molecules or ion clusters in the air. They play an essential role in maintaining the charge balance of the atmosphere.
The most effective type of air filter for fine particulate matter, used in many air conditioners and HVAC systems, are HEPA filters, which "theoretically remove remove at least 99.97% of dust ...
2. The very young and very old are especially vulnerable. Dr. Ethan Sims, an emergency room physician at St. Luke’s, said people over 65 and under 12 are among the most vulnerable.
Air ion (afaik) means that the air molecule has gained or lost an electron. For instance, N 2 + or O 2-would be considered air ions. ~Adjwilley 22:05, 3 March 2013 (UTC) I understand that a negative ion is an element or molecule with one or more electrons than protons, but air is a mixture of gasses, not an element or molecule.
