The dataset contains the results of a study examining the use of different flow-rate hood fans in reducing air pollution exposure during and after cooking. Tests were carried out in the Canadian Centre for Housing Technology's twin research houses, in Ottawa, Ontario. The same cooking protocol was conducted 60 times on a gas stove, testing 6 different flow rates on three different over-the-range exhaust fans, while continuously measuring ultrafine particles (UFP), Fine Particulate Matter (PM2.5), Nitrogen dioxide (NO2), and Nitrogen monoxide (NO). The fan was operated during cooking for all tests and then either turned off or left on after cooking for the duration of the three hour test. The dataset contains the estimated pollutant decay rates, peak concentration, source emission rates, and integrated exposures to measured pollutants following the cooking test.
