Sample size of one, but ours is pretty effective (and loud lol)! We have an old Wolf stove, the fan vents directly outside, and I have been ad hoc testing it with an Awair sensor over the past year. Without running the fan the Awair score drops from the 90s to the 40-50s pretty quickly when running the stove (either oven or surface) and takes about 45 minutes to return to normal once the stove is off. With the fan on high the score stays in the high 70s to 80s. My ears, tho...
