Air ioniser
Air Ioniser
An Air Ioniser (pronounced: /ɛər aɪˈɒnɪzər/) is a device that uses high voltage to ionise (electrically charge) air molecules. Air Ionisers are used to eliminate the occurrence of air-borne bacterial infections and to reduce static electricity build-up in electronics.
Etymology
The term "Air Ioniser" is derived from the process of ionisation it performs. The word "Ioniser" is a combination of the word "ion", which is a charged atom or molecule, and the suffix "-iser", which denotes an agent or device.
Function
Air Ionisers generate ions, which are atoms or molecules that have gained or lost an electrical charge. They create negative ions in the air, which are then attracted to positively charged particles such as dust, bacteria, pollen, smoke, and other allergens. The particles are then neutralised and removed from the air, improving the air quality.
Types
There are two major types of Air Ionisers: Fan-based Ionisers and Electrostatic Ionisers.
- Fan-based Ionisers use a fan to circulate air through the device, where it is ionised and then released back into the room.
- Electrostatic Ionisers work by creating an electric field that ionises the air passing through it.
Related Terms
- Ion: An atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
- Ionisation: The process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons, often in conjunction with other chemical changes.
- Electrostatics: The branch of physics that deals with the phenomena and properties of stationary or slow-moving electric charges.
