(Wall-Mount Exhaust Fan) Comparing Apples To Oranges? Don't get fooled - some desperate fan manufacturers are advertising their fan CFM/watt and CFM, but are not disclosing that those performance numbers are at non-real-world .00" S.P. vs. .05"S.P. (as listed on electric company rebate lists). Some are advertising "highest CFM/watt", but are not disclosing that it is for low vs. high speed and for .00" S.P. vs. .05"S.P. Some are also comparing the price and performance of their fans WITHOUT a shutter to ours WITH a shutter. Demand straight talk!
