If the air in your car seems stuffy, it may be because the cabin air filter needs replacing, a routine maintenance task. Different models of vehicles have different locations for the air filter, but with a little searching, it should be easy to find.
The cabin air filter filters the outside air coming into the vehicle.
The useful life of a filter depends on external conditions and the air quality in your area; they usually require replacement around 15,000 miles, or every year.
The cabin air filter is rectangular in shape and protected by a plastic cover that can be removed, usually with a tab.
The cabin air filter may be in the outside air intake under the hood, or it may be inside the vehicle, around the dashboard on the passenger's side.
The car's owner's manual should include information about where to find the cabin air filter. The instructions will also explain how to replace the filter when necessary, including where to purchase a new one.
