Precautions to Take When Replacing a Cabin Air Filter
Cabin air filters should be replaced regularly to prevent pollen, dust, and other outside contaminants from entering the vehicle. Some cabin air filters even have activated charcoal to filter smells. There are a few precautions to take when replacing the cabin air filter. The cabin air filter is typically located above the blower motor. Here it traps contaminants before they can be pushed into the vehicle by the blower motor. If not re-placed, the cabin air filter may collect excess debris on top that may then fall into the blower motor housing, causing irregular noises in the blower motor housing and or/ the vents.
While replacement periods for cabin air filters vary based on location, usage, and where a vehicle is stored, it is typically recommended to replace the cabin air filter every time the air filter is replaced, on average every 15,000 to 25,000 miles.
