Fine particulate matter infiltration at Western Montana residences during wildfire season.

ABSTRACT:

Background/aims

Wildfire air pollution is a growing public health concern as wildfires increase in size, intensity, and duration in the United States. The public is often encouraged to stay indoors during wildfire smoke events to reduce exposure. However, there is limited information on how much wildfire smoke infiltrates indoors at residences and what household/behavioral characteristics contribute to higher infiltration. We assessed fine particulate matter (PM_2.5) infiltration into Western Montana residences during wildfire season.

Methods

We measured continuous outdoor and indoor PM_2.5 concentrations from July-October 2022 at 20 residences in Western Montana during wildfire season using low-cost PM_2.5 sensors. We used paired outdoor/indoor
