The World Health Organization estimates significant air pollution–attributable deaths, including 11% of lung cancer deaths, 18% of COPD deaths, and 23% of pneumonia deaths (www.who.org). (Carlsten C, et al. Europ Respir J. 2020;55[6]: 1902056).
The Environmental Protection Agency uses air quality (AQ) monitors around the country to track ambient pollution levels. These real-time data are available to the public on AirNow.gov; however, these data do not reflect indoor air pollutants. Thus, AQ monitors may not accurately represent the total air pollution exposure to patients.
Low-cost AQ monitors available for purchase enable indoor AQ monitoring.
Unfortunately, many indoor air pollutants do not have well-established safe levels. Although several devices detect specific pollutants like volatile oxygen compounds or particulate matter, other harmful compounds may remain undetectable and unmonitored. Even if high pollutant levels are detected, most devices are not designed to alarm like smoke and carbon monoxide detectors (www.epa.gov).
Although efficacy data are limited, several laboratories, such as the Indoor Environment Lab at Berkeley, have conducted performance evaluations. In a study of 16 devices publicly available for purchase, the devices tended to underreport pollutant levels by nearly 50%. Nevertheless, most devices successfully detected the presence of pollutants (Demanega I, et al. Building and Environment. 2021;187:107415).
Regardless of these limitations, low-cost AQ monitors may empower patients to intervene on unsafe household conditions and minimize their risk of poor lung health.
