Exposure to fine particulate matter (PM2.5) has been identified as a significant public health issue. PM2.5 of outdoor origin accounts for around 50% of indoor PM2.5. Reductions in exposure to PM2.5 of both outdoor and indoor origin can be made in new and existing residential buildings. The practicality of reducing indoor exposures to PM2.5 of outdoor origin by applying airtightness in combination with filtered outdoor air to slightly pressurize new and existing residential buildings is discussed. Potential reductions of exposure to cooking related PM2.5 by applying the information to the design and installation of range hoods is also discussed.
