"Wildfire smoke can pose a significant hazard to human health, mainly due to its composition and prolonged exposure. Although wildfires are local events, wildfire smoke disperses horizontally and vertically in theatmosphere and could be transported a long distance form the point of origin. As a result, the impact of wildfires extends far beyond their physical footprint, putting a large population at risk. Induct air filters are the most commonly used method to maintain a habitable indoor air quality during wildfire smoke seasons, however, the standard test for evaluating their performance uses an aerosol of salt which is different from smoke composition. In this report, the development of a bench-scale setup for testing the performance of the in-duct air filters exposed to simulated wildfire smoke is presented. The setup consists of a tube furnace to generate the simulated smoke and a chamber to house the filter and the instrumentation. Pine needles and wood chips were used in a tube furnace at oxidative pyrolysis conditions to produce the smoke. The setup showed reproducible production of smoke and thorough mixing of particulate matter (PM) in the chamber. This setup could be used to evaluate the short term and long-term performance of in-duct air filters"--Executive summary, page 7. Air filters Canada Testing.
