Product review (3 stars): How to know if the machine performances as it's supposed to do the job?
Just installed the hood yesterday. It looks good. HOWEVER I am not convince  that it has 800 CFM, as it could not even suck up a square of 3"x3" THIN toilet paper that is only 4" below the baffle filter  (yes, I held the paper 4" below the filter), when it operated at the highest speed . I wonder if anyone has done the similar experiment.  Does the experiment say something about it? I did the experiment because I don't feel the "powerful" suction at all.
