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.
Exhaust fan on timer? My wife and I recently moved into a new home to us, built in 2000. There is an exhaust fan in the laundry room that turns on and off on it's own, almost as if it is on a timer. The wall switch will not turn it off while it is running. It runs while the wall switch is in either the off or on position, the only way to turn it off is to position the switch in between on or off, straight out / 90 degree angle from the wall. The remainder of the time, the fan works as should and turns off and on with the wall switch. I have also noticed that the exhaust fan in one of the upstair bathrooms comes on at the same time the fan in the laundry mysteriously turns on. Is this normal for an exhaust vent to be on a timer or some sort of sensor? Thanks
