It is an undisputed fact that roadways are some of the major
sources of air pollution. Therefore, as you are driving, you are forced to
breathe the air tainted with exhaust fumes, dust and soot particles, many of
which may pose a hazard to your health.
Not to be left out are pollen, mold and other allergens that enter your
vehicle on your commute.
Many GM vehicles are combating the pollutants making their
way into your vehicle with a cabin air filter.
It is a filter, usually situated under the dash or behind the glove box
that collects the dust, pollen and other air borne pollutants that enter your
vehicle through the heating, ventilation and air conditioning systems.
It is recommend that your cabin air filter be replaced every 12,000 km or at least once a year
— how often can depend on how much you
drive and where. If you drive in heavy traffic in an urban area that has poor
air quality, you could need to replace the filter more often.
Some signs that you need a new cabin air filter are reduced
air flow through your HVAC system, such as when you crank up the fan too high
and you get more noise than results. Another is persistent bad odors. Even if
you don't have these warnings, you should have the filter checked at least once
a year, and you may be able to do that yourself.
The next time you book in for an appointment ask them to
check your cabin air filter.
