Candles add to the warmth & atmosphere of a home,
but some candles can contribute to an indoor air pollution
problem by emitting particulate matter (candle soot) into
the air. Candle pollution not only discolors the walls, ceilings
and contents of a home it can also contaminate the ventilation
system's ductwork. This is especially true of ducts constructed
from fiberglass "duct-board". It appears that petroleum-based
(paraffin) candles and scented and/or aromatic candles are the
worst offenders. Most candles on the market today are made
from paraffin wax or a blend of paraffin and other waxes.
Paraffin is a derivative of petroleum. When burned they
release carcinogenic toxins such as benzene, toluene,
formaldehyde, acetaldehyde, acrolein and soot into the air.
The emissions from paraffin candles contain many of the
same toxins produced by burning diesel fuel. It is like
starting up a diesel engine inside you home!
