dust in bathroom exaust fan
Jon Derman
I get lots of dust collecting in one of my bathroom exaust fans -- and
then it settles on every surface in the bathroom. The fan is mounted
on the bathroom ceiling, where there is a hole going through to the
attic and flexible duct-hose goes up to the roof.
I have this exact same kind of fan set up in two bathrooms, but the
dust problem is sooo much worse in one bathroom.
I suspect the dust is coming down into the bathroom from the attic.
Sound reasonable? Any suggestions on how to reduce the dust?

I suspect the flexible duct only goes into the attic and lays on top
of the insulation. If it's loose insulation, than some of it might be
getting sucked back down the exhaust hose due to pressure differences
between the house and the attic.
I have three ideas.
1. Make sure the end of the hose is well above the attic floor. Tie
it to a rafter with wire.
2. Take a piece of furnace filter and form a cap for the end of the
hose. Secure it with duct take.
3. Get a dryer vent and secure it horizontally to a rafter and attach
the hose to it with duct tape.
If your fan vents to the outside than I have no ideas.

You might want to try some expandable caulk around any loose fitting
of the fan and the hole it is in. Don't over do the caulk as it will
expand and if you use to much you can have problems. Another thing
would be to place some insulation in the same area but this isn't as
good an idea as it may too loose particles into your room.
If this sealing doesn't do the job you might want to try a filter of
some sort on the exhaust pipe itself. Maybe the dust is coming from
outside if this room vents to a particularly dusty area outside.

On the subject of bathroom exhaust fans; what is the proper way to vent a
bathroom fan? Can it just go into the attic or must if go to the outside
of the house? I just installed one last fall and tried to do my homework
ahead of time but couldn't get a straight answer from anyone. It was the
usual scenerio, ask 3 people and get 3 different answers. I ended up
running flex pipe (dryer vent pipe) into the attic and positioned it
directly below a roof vent. Seems to be satisfactory. Any comments out
there? All are welcome.
Thanks,
Steve

The proper way to vent anything is to the outside. In the case of a
bathroom vent you are actually just moving the steam (moisture) to
you're attic. If the bathroom gets allot of use (showers etc.) you
could be putting allot of moisture into you're attic and can cause
wood rot and mold.
