1. A range hood for ventilating an indoor environment adjacent a cook top, the range hood comprising:
a ventilation fan adapted to move air within the indoor environment; and
an indoor air quality event detector comprising
a temperature sensor configured to measure one of a temperature of one or more objects and a temperature at the ventilation fan,
a pollutant sensor configured to measure the levels of one or more pollutants in the indoor environment,
a humidity sensor configured to measure a level of humidity in the indoor environment,
wherein the indoor air quality event detector is configured to selectively operate the ventilation fan in
a low speed when the temperature is above a first threshold level, the humidity level is below a second threshold level, and the pollutant level is below a third threshold level,
a high speed when the temperature is above the first threshold level, the humidity level is above the second threshold level, and the pollutant level is above the third threshold level, and
a medium speed when the temperature is above the first threshold level but the conditions for operating the ventilation fan in the low speed and the high speed are not met.
