Does recirculated air get filtered?
Most of the time, air flows through the cabin filter from outside the vehicle. But, when the HVAC controls are set to recirculation mode, interior air is blown through the filter before re-entering the cabin. This allows the filter to remove harmful contaminants that are already inside the vehicle.
Cabin air filters can capture dust, bugs, leaves, and other various types of debris. A dirty air filter can certainly impede your air conditioner’s ability to cool and after time could cause unnecessary strain on the entire system.
How often is the cabin air filter replaced?
The time period for replacing your cabin air filter is dependent on the make, model, and year of your vehicle, so you’ll want to check your owner’s manual for verification. In general, though, most cabin air filters should be replaced somewhere between every 15,000 and 30,000 miles.
