Study Shows Indoor Air Purifiers That Produce Even Small Amounts Of Ozone May Be
Scientists also discovered that ozone produced by air purifiers adds to ozone already present in any room - a prediction that had never been experimentally verified in a realistic indoor environment.
"These results mean that people operating air purifiers indoors are more prone to being exposed to ozone levels in excess of public health standards," said Sergey A. Nizkorodov, assistant professor of chemistry in the School of Physical Sciences at UCI.
