Guidelines for Drinking-water Quality - Bromide in Drinking Water

This informational article reviews the health and safety concerns associated with ozone generators marketed as indoor air cleaning devices. Drawing on findings from the U.S. Environmental Protection Agency (EPA), the document explains the properties of ozone, its potential health effects, and the limitations of using ozone for indoor air purification. The publication highlights that ozone concentrations required to effectively remove many indoor contaminants often exceed established public health guidelines and may pose risks to occupants. It also discusses alternative approaches to improving indoor air quality, including source control, ventilation, and proven air cleaning technologies, providing consumers with a science-based perspective on the use of ozone generators in occupied spaces.
