: My stinking feces has a powerful odor that fills my 9' x 5' x 8' bathroom with a stench that would make one's eyes water. Does anyone have any recommendation on what brand or size exhaust fan would handle the sickening gases that fill this room?

Stul,
If I were you, I would be thinking of a 110 CFM fan. Broan and Panasonic make nice ones.
