Winter air pollution is mainly caused
by small particle pollution, or particulate
matter (PM). The two major winter sources of
PM in the Bay Area are residential wood burning
and motor vehicles.
can help reduce winter air pollution if you:
Do NOT burn wood.
Retrofit your fireplace to burn natural gas,
a cleaner alternative to wood burning.
If you must burn wood, burn less and use only
dry, clean, seasoned wood, and nonglossy white
paper. Moist, or "green" wood smolders
more, producing greater amounts of harmful air
Check the chimney. Where there's smoke, there's
a bad fire. Excess smoke means that the fire
isn't burning properly.
