Kitchen range hood

Particles generated from cooking activities are the biggest contributor to the concentration of indoor particles in most homes, and they are not easily removed without natural or mechanical ventilation. As more focus is directed on human health, kitchen range hoods have drawn increasing attention and their performance in various conditions needs to be evaluated. Consequently, in this study, we performed measurements to establish the particle capture efficiency of a kitchen range hood for various particle diameters at different exhaust flow rates.
