<h4 class="dechead">On One Hand: Ionizers Clean the Air
Ionizers have been used in some hospitals, and have been shown to reduce the bacterial content of the air. In one case, airborne infections in the intensive care ward at St James's Hospital in Leeds, UK were almost entirely eliminated, according to New Scientist magazine.
On the Other: Ionizers Do Not Directly Impact Humans
Research on how ions influence the health of humans remains inconclusive, but many scientists agree that ions do not directly impact people. Studies that have examined the direct relationship between ions and humans have shown mixed results. The only thing that can be concluded is that any benefits of ionizers are indirect, resulting from cleaner air.
Bottom Line
Air ionizers have been shown to clean the air and reduce airborne bacterial infections, though research still needs to be done to fully understand the process by which ionizers do this. Though ionizers do not directly impact health, they can certainly be beneficial in creating a healthier environment.
