The cabin air filter for a Chevy Tahoe is located on the passenger side of the vehicle under the dashboard. However, not every Chevy Tahoe has a cabin filter. Models later than 2003 do not include them as a standard feature.
A cabin air filter is different from an engine air filter. The purpose of a cabin air filter is to improve the comfort of a vehicle's passengers. The filter removes various air pollutants, such as dust and pollen, from the air inside the car. Cabin air filters connect to a vehicle's heating and air conditioning system and are easy to replace when they become dirty and ineffective.
