"These devices are marketed to reduce pollen and particulates in room air."
BUT the consumer should be aware:
"...a chemistry professor at the University of California at Irvine, noted that all “ionic” air purifiers emit some ozone.
They emit small amounts of ozone as a byproduct of this ionization process. The other machines, which employ ozonolysis, emit more ozone.
In a small and poorly ventilated room, the ozone adds to existing ozone and creates potentially unhealthy concentrations.
"People operating air purifiers indoors are more prone to being exposed to ozone levels in excess of public health standards," Nizkorodov said."
