Car Air Filter

Fresh air in your car – air filters

Today, most cars and trucks today have air filters that clean the outside air before it gets blown into your car. What they clean, specifically, is particulate matter, such as dust and pollen. This may not seem like a major thing to some, but for those that suffer from asthma and allergies, clean air inside a car can be a godsend.

These filters are generally referred to as “cabin air filters.” They do a great job of keeping the air in your car clean, but they do get dirty over time. Most automotive manufacturers suggest that you change your cabin air filter every 10,000 to 15,000 miles in “standard environments.”  If you drive in dusty environments, you may have to change your filter more often.


Cabin air filters can sometimes be changed by the car owner. Obviously this can save you some money but sometimes they can be very difficult to get at. For example, many cabin air filters are located behind the glove box and to get at them, you need to drop the glove box from its support fasteners and sometimes other components too. We advise that you look online to see how to change the filter in your car and decide if you want to take it on.

Professional replacement

If you find that replacing a cabin air filter is a major operation, take it from Neuwirth Chrysler of Wilmington, NC, it may be best to let a factory-trained mechanic do it for you. They will know exactly how to do it without breaking anything under the dash. In addition, they may have some tricks to make the process easier.

More expensive than engine filters

By the way, you may be surprised at how expensive replacement cabin air filters are.  Its primarily because of the filter paper is somewhat exotic with very fine pores. In general, cabin air filters are typically twice the price of common engine air filters which don’t have to catch miniscule particles such as fine dust and pollen.

Take a look

If you elect to have your dealership, replace your filter, ask to see it before they toss it.  You might be surprised to see that stuff that it has caught.  It may have insects, leaves, dirt and all sorts of stuff attached to its surface.  If you see a lot of junk on the surface, you may want to replace it more often than the factory recommends.
