Ionisers are quickly gaining in popularity overseas and in Australia. Air ionisers are now being used in hospital clean rooms, homes and offices to help to improve the air quality in these environments, remove dust, bacteria, smoke and odours from air, and relieve symptoms caused by polluted air such as sinuses, headaches, itchy eyes, and respiratory sicknesses.
While many have claimed that air ionisers do not work, various research papers indicate that there may be some truth to the benefits of air ionisers and negative ions after all. We have compiled some useful research papers below that may help you reach a decision on your own.
British research at the center for sport and exercise sciences in Liverpool discovered that negative ions helps to improve physiological states during rest after exercise. (http://www.nutricentre.com/Start/research_feb03.aspx#4)
Air ionisers can help to wipe out hospital infections (http://www.newscientist.com/article/dn3228)
Ionization is obligatory in many Russian and European hospitals.
In March of 1999, Good Housekeeping Magazine had its engineers test an ionizer by using a smoke test, and found that it cleared out the smoke in a tank.
A recent study by the U.S. Dept. of Agriculture found that ionizing a room led to 52% less dust in the air, and 95% less bacteria in the air (since many of the pollutants found in the air reside on floating dust particles).

Approved by the U.S. FDA (Food & Drug Admin.) as an approved allergy treatment
U.S. Dept of Agriculture found that ionizing also kills germ. (http://www.ars.usda.gov/research/publications/publications.htm?SEQ_NO_115=112644)
A 2006 research paper found that negative ions can help in treating seasonal affective disorder (http://www.apa.org/monitor/feb06/sad.aspx)
A 2008 research paper explained the physical behaviour of ions in indoor air (http://eprints.whiterose.ac.uk/7785/)
