CNN —Risks from the Covid-19 pandemic and increasingly intense wildfire seasons have sparked interest in air purifiers as a tool to keep indoor air healthy. But experts say they can be just as important to help manage indoor air pollution when there isn’t an acute air crisis. Other interventions – particularly ventilating indoor air by introducing new outdoor air and directly removing the source of indoor air pollution – may have a bigger impact on health outcomes, and they’ve been the focus of recent federal action. What air purifiers can and can’t doAir purifiers can’t fully eliminate indoor air pollutants, but they can help with the process of cleaning indoor air and come with little to no risk, experts say. But indoor air quality is not regulated in the same way that outdoor air quality is in the United States, and it’s been the subject of far less research.
