Put simply, an air ionizer is a small device that uses a high level of voltage to electronically charge air molecules. But there is a lot more to it than that.
Air ionizers are most commonly used within air purifiers. The majority of commercial air purifiers that you would encounter today are designed to generate negative ions. That is how they work!
Negative ions (otherwise known as anions) are particles made up of one or more electrons, conferring a net negative charge to the particle.
Within the air purifier, the airborne particles are attracted to the electrode in an effect which has been compared by many to static electricity.
One of the most common mistakes that people make is confusing ionizers with ozone generators.
This is understandable since both operate in similar ways within whatever appliance they are found in.
However, while ozone generators are optimised to attract an extra oxygen ion, ionizers use electrostatically charged plates to ultimately produce gas ions.
The battle against hospital infections
One of the most innovative ways in which air ionizers have been utilised in recent times is by a hospital in Britain.
St James’s Hospital in Leeds carried out a trial in 2003 where they installed a negative air ioniser to counteract a succession of bacterial infections within an intensive care ward.
It was a groundbreaking use of ionizers at the time and led to the infection rate within the unit eventually dropping to zero at the end of a yearlong trial.
The results stunned many leading medical professionals and have led to further tests involving air ionizers to see what other ways they can be positively applied.
