Overview

A representative telephone survey of 2,019 California adults was conducted to determine the extent to which Californians purchased and used indoor air cleaners, specifically models that produce ozone either intentionally or as a by-product, as well as the reasons for their purchase, the frequency and duration of their use, and to determine other factors that may impact public health.

Fourteen percent of California households own an air cleaner. Ten percent of California households own an air cleaner that produces ozone intentionally (often referred to as "ozone generators") or as a by-product: two percent (2%) of California households own an ozone generator that intentionally emits ozone, while eight percent (8%) own an air cleaner that may emit ozone as a by-product. An estimated 828,000 Californians (about 282,000 households) may be intentionally exposed to potentially harmful levels of ozone.

Many more residents may be exposed to lower ozone concentrations from by-product devices. Californians purchase air cleaners primarily for health reasons, and most use their air cleaners continuously every day.
