In vehicles built in 2007 and later you will find 80 percent of them have a cabin air filter and its function is to protect drivers and their passengers from contaminants such as pollen, mold spores, dust and other small and annoying particles. The cabin air filter is located on the passenger side of the vehicle and is most often, but not always tucked behind the dash around the glove compartment area. Whenever you turn on your defroster, air conditioning or heater it captures the debris so it doesn’t get into the cab of your vehicle. It is a very busy part and needs to be replaced at least once a year. If you or a passenger has severe allergies you may want to get it replaced more often. A clean cabin filter also helps prolong the life of your vehicle’s heating and air-conditioning system because it keeps debris and corrosion away from the evaporator core.
We get calls when customers turn on their heater fan wanting to know what that annoying rattling noise is from time to time. It is usually captured leaves or food stuffs left behind by rodents. Next time you get your cabin air filter changed you might ask to have a look at it. You will be very amazed about what it has collected and very thankful too that all that debris didn’t circulate into the cab of your vehicle.
Cabin air filters are becoming more sophisticated…some even eliminate odors. The good news is that it is usually a quick item to replace (depending on where the manufacturer placed it) and it is inexpensive. Next time you have your car serviced, don’t forget to get this part replaced. You’ll breathe easier…I guarantee it.
