This is a device that many manufacturers began adding to their cars’ A/C and heating systems to filter the air coming into your car’s passenger compartment. It’s designed to remove the dust and soot, and provide you with fresh air to breathe.
While a clogged cabin filter won’t affect the car’s performance, it will affect the quality and volume of fresh air coming in through your car’s heating and air conditioning system.
Air Filter Replacement
Many manufacturers suggest checking the cabin filter occasionally. But in most cases it takes more than a little effort to reach the cabin filter, so you’re probably better off just having it replaced every couple years or so. Check your car’s owners manual for the factory replacement recommendation.
