2. Air ioniser - Wikipedia

   en.wikipedia.org/wiki/Air_ioniser

   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.

3. Do Air Purifiers Actually Work? Here's What Experts Say - AOL

   Note that some air purifiers use ionizers to help attract particles like static — negative ions bond to dust and allergens and make them settle out of the air.

4. Air purifier - Wikipedia

   en.wikipedia.org/wiki/Air_purifier

   Active air purifiers release negatively charged ions into the air, causing pollutants to stick to surfaces, while passive air purification units use air filters to remove pollutants. Passive purifiers are more efficient since all the dust and particulate matter is permanently removed from the air and collected in the filters. [ 15 ]

5. GPS Air - Wikipedia

   An additional study done at the University of Arizona found that the devices did indeed kill microorganisms when they were producing ions at "62,000 negative ions per cubic centimeter", but that this was an order of magnitude higher than the ion production rates of the devices under normal usage. Furthermore, other studies have found that ...

6. Negative air ions - Wikipedia

   en.wikipedia.org/wiki/Negative_air_ions

   Common gases that produce negative air ions include single-component gases such as nitrogen, oxygen, carbon dioxide, water vapor, or multi-component gases obtained by mixing these single-component gases. Various negative air ions are formed by combining active neutral molecules and electrons in the gas through a series of ion-molecule reactions ...

   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.

   In January 2016, Dyson released the Dyson Pure Cool air purifier. It uses the same Air Multiplier technology to blow air, as well as a 0.99 micron HEPA filter to trap suspended particles. Along with a coarse filter to trap slow particles, the unit uses low-force velocity to trap fine particles within the filter as well. [46]
