Abstract

This study has investigated the effect of a kitchen exhaust hood on the reduction of exposure to ultrafine particles (UFP) from a gas stove. Size-resolved UFP ranging from 2 nm to 100 nm were monitored in a manufactured test house (volume of 340 m3), using a Scanning Mobility Particle Sizer (SMPS). The flow rate of the range hood exhaust fan was varied from 100 m3/h to 370 m3/h. The majority of particles released from the gas stove were smaller than 14 nm. The effectiveness of the range hood for removing particles varies with the range hood flow rate, particle size and burner position. Higher particle removal efficiency for the gas stove was achieved with higher range hood flow rate and larger particles.
