Use of air ionisers as an experimental non pharmaceutical treatment
Negative air ionization therapy (NAIs) uses air ionisers as a non pharmaceutical treatment for respiratory disease, allergy, or stress related health conditions. The mainstream scientific community considers many applications of NAIs to be pseudoscience. Many negative ion products release ozone, a chemical known to cause lung damage.

For Seasonal Affective Disorder (SAD), a randomized controlled trial (RCT) comparing high (4.5x1014 ions/second) and low (1.7x1011 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. An older RCT conducted by the same authors also found air ionization effective for SAD. A 2007 review considers this therapy "under investigation" and suggests that it may be a helpful treatment for SAD. An RCT comparing the short term effects of bright light, an auditory stimulus, and high and low density negative ions on mood and alertness in mildly depressed and non depressed adults found that the three first (active) stimuli, but not the low density placebo, reduced depression on the Beck Depression Inventory scale. The auditory stimulus, bright light, and high density ions all produced rapid mood changes with small to medium effect sizes in depressed and non depressed subjects. Researchers have continued to cite a dearth of evidence about the effects of negative air ionization. "The presence of NAIs is credited for increasing psychological health, productivity, and overall well being but without consistent or reliable evidence in therapeutic effects and with controversy in anti microorganisms," researchers wrote in a 2018 article published in the International Journal of Molecular Sciences.
