Indoor Conditions

Abstract Plants have the ability to absorb and degrade VOCs (volatile organic compounds). Foliage can intercept particulate matter (PM) and thus, help to reduce its concentration in the air. Plants can be used as filters in indoor conditions adding an ecosystem service to the decorative purpose. A plant-based air filtration system that actively improves indoor air quality has been developed and installed at a students’ residence at Brunel University, London. This unit replaces an existing window with a mini-greenhouse containing upwards of 30 plants and is connected to an air circuit to treat the indoor air. A monitoring plan is collecting data on the performance of the solution until at least the end of 2021. Preliminary results are presented, which indicate good effectiveness at reducing tVOCs and lower efficiency at reducing PM.

Pollution Events

Effective strategies to reduce indoor air pollutant concentrations during wildfire smoke events are critically needed. Worldwide, communities in areas prone to wildfires may suffer from annual smoke exposure events lasting from days to weeks. In addition, there are many areas of the world where high pollution events are common and where methods employed to reduce exposure to pollution may have relevance to wildfire smoke pollution episodes and vice versa. This article summarizes a recent virtual meeting held by the United States Environmental Protection Agency (EPA) to share research, experiences, and other information that can inform best practices for creating clean air spaces during wildland fire smoke events. The meeting included presentations on the public health impacts of wildland fire smoke; public health agencies' experiences and resilience efforts; and methods to improve indoor air quality, including the effectiveness of air filtration methods [e.g., building heating ventilation and air conditioning (HVAC) systems and portable, free-standing air filtration systems]. These presentations and related research indicate that filtration has been demonstrated to effectively improve indoor air quality during high ambient air pollution events; however, several research questions remain regarding the longevity and maintenance of filtration equipment during and after smoke events, effects on the pollution mixture, and degree to which adverse health effects are reduced.
