Ceiling fans are for removing moisture, not odors, however they do
pull gas and harmful germs up into the bathroom air. A vented toilet
seat (Miracle Seat - www.miracleseat.com) that comes equipped with a
fan vacuums toilet odors and germs from the toilet bowl before they
can escape into the air. The exhaust duct can be connected to the
dryer duct, an existing ceiling fan duct or run to an exterior vent.

I read about something like this for outhouses in Popular Science a
long time ago. It was solar powered and drew the air down the "hole"
and up into a tall vent. Probably too expensive to implement.

Very forthright of you to post the Cecil Adams link on your website. I
especially like the following:

"As Professor Gerba's research would later determine, however, the
bathroom was hardly the most dangerous part of the house,
microbe-wise. The real pesthole: the kitchen sponge or dishcloth,
where fecal coliform bacteria from raw meat and such could fester in a
damp, nurturing (for a germ) environment. Next came the kitchen sink,
the bathroom sink, and the kitchen faucet handle. The toilet seat was
the least contaminated of 15 household locales studied. 'If an alien
came from space and studied the bacterial counts,' the professor says,
'he probably would conclude he should wash his hands in your toilet
and crap in your sink.'"

[Note to everyone: Might want to follow the medical links on the
website because even while debunking the efficacy of this product,
they alert you to areas that need attention and how to deal with
them.]
