conditioning system. It catches dust, pollen and other airborne material that

respiratory on when it should be replaced vary by manufacturer - some say every
12,000 or 15,000 miles, others longer - and how often can depend on how much you
drive and where. Check the maintenance schedule in your owner's manual. If you
drive in heavy traffic in an urban area that has poor air quality, you could
need to replace the filter annually or even more often. However, that also could
be true in a desert climate where there is a lot of 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

at least once a year, and you may be able to do that cabin air filters are
located behind the glove box and are easily accessible by freeing the glove box
from its fasteners (instructions should be in the owner's manual). Others are
located under the dashboard and may not be easy to reach, or under the hood

surface that comes in contact with incoming air. You'll know it's time for a new
cabin air filter.
