Your car’s air filter keeps pollutants from coming in through the vents. The air filter has a pretty important job, so you want to treat it well. Plus using an old air filter long past its life can lead to major problems for your air conditioning system. And trust us, you don’t want that. Replacing your full AC unit can run anywhere from $1,000 to $4,000.
Change your air filter every 12 months or 12,000 miles.
