Holy moly loud ! This fan is uber loud, but does have the commercial filters that does the job. Bit of a pain in the butt. It rattled like mad and we tried every which way to adjust the metal to stop the rattling - contacted seller and they were very nice and sent us replacement. It no longer rattles but it is loud as heck. Overall I'm happy it takes care of smells but I don't know you can get quieter due to its high cfm output. Has a timer and sometimes when it overheats it shuts off on its own.
