I HAVE SEEN THIS MANY TIMES HERE IN sOUTH cAROLINA. pEOPLE WHO BURN
CANDLES HAVE A LOT OF SOOT IN THE AIR OF THEIR HOMES. bECAUSE THE SOOT
PARTICLES ARE SO SMALL, IT TAKES A LONG TIME TO SHOW UP ON STANDARD AIR
FILTERS.

Oops, sorry about the caps, caps lock was on :-)

The carpets will act like filters where doors are closed and you will
get soot under the doors on the carpet when the doors are closed.

Remember that any time you have a yellow flame, you have incomplete
combustion. That means that you will produce soot as well as carbon
monoxide. That is why you have to be careful not to have a yellow
flame in a gas furnace, it will soot up over the course of the heating
season.

The soot that is on your furniture will be deposited inside your
heating ducts as well, but it is not coming from the ducts, it is
coming from the candles.

If you are breathing soot, you are breathing carbon monoxide as well.
