Product review (1 stars): the inspector called this a toy
I didn't know anything about this type of appliance.  My renovation thought me a lot.

The two things that I should have  looked at was the sonos rating which should be below 1 and the CFM rating should be above 300.

This sonos rating  for this is 4.5 meaning its really noisey. And the CFM rating was 75 which just a basic fan.  They can go as high as1200, so in scale you  a have hand fan in a heat wave.
