Quick Answer. Ductless bathroom fans remove odors and germs by filtering the air through an activated charcoal filter. These fans have a lower blade speed, also called a tip speed, which allows more air to be sucked up into the filter. Once cleaned, the air is re-circulated back into the bathroom.
So-if you have 1 toilet (50 CFM), 1 shower (50 CFM) and 1 whirlpool tub (100 CFM) - you will need a 200 CFM Fan. The Pansonic FV-20VQ3 would work well in this bathroom. An inline fan kit that would work well in this bathroom is the Fantech PB 270-2. This kit includes a 200 CFM fan and allows for 2 exhaust grilles in the ceiling. Static Pressure and Duct Run: A ventilating fan must overcome resistance when pushing air from the inlet, through the duct, to the outside of the building.
