Did you know that most cars made after 2000 have a cabin air filter? (CAF) A lot of people don’t, but not changing yours regularly can result in health problems for you and your passengers, and extra wear and maintenance for your car’s HVAC system.  For the majority of cars built after 2000, CAFs are either standard equipment, or are included as an option. If you’re not sure if your car has a CAF, consult your owner’s manual. Many CAFs are located either beneath the hood or under the dashboard, often behind the glove compartment. Changing your car’s CAF is usually a simple and easy proposition often taking less than 10 minutes to undertake. Most can be changed with simple hand tools, or simply by hand.

The importance of keeping a clean CAF in your car can’t be overstated. When the CAF becomes clogged and dirty, those inside the car start to breathe the outside air which is often polluted with contaminants and noxious gases. Also, your car’s HVAC will start to be taxed and have to work harder than it has to if the CAF isn’t changed regularly. Recommendations call for the CAF to be changed every year or 10,000 to 15,000 miles.

Most CAFs are composed of three layer of filter media: two outer layers that capture larger particles  such as pollen, dust, mold spores, soot, and smog, and an inner layer made of activated charcoal or electrostatically charged to remove gases and odors from the air entering your car’s interior. Filters Fast offers a wide selection of CAFs for many different makes and models of cars. To see if we carry your car’s CAF, simply go to and type your car’s make and model into our search bar. Changing your CAF regularly can save your health, and extend your car’s life.

Help Your Car’s Engine Breathe Easier: Change Your Air Filter

Clean air filters will prevent dirt and debris from building up in your engine.

Are you one of the many drivers who neglects to change their car’s air filter on a regular basis? With the purchase of a new car, your sales person will normally include a maintenance schedule of things to have completed such as oil changes, tire rotations, battery checks and other standard items while your car is under warranty.

Amid respiratory concerns about outdoor air pollution, a vehicle’s air filter functions similarly to your lungs. A clogged air filter comes from gradual buildup of dirt and debris. It is recommended that you change your air filter every 12,000 to 15,000 miles. If you live in a rural area where you frequently travel down dirt or sandy roads, you will more than likely have to change your car’s air filter more regularly. The car air filter for your engine is called an internal combustion filter. This is different from the cabin air filters that is used in your car’s air conditioning system.

There are 3 types of internal combustion filters:

  1. Paper air filters are made from specially treated, industrial grade paper that is pleated like an accordion. These standard filters are relatively inexpensive and easy to replace if you want to do-it-yourself.
  2. Foam air filters are made from polyurethane foam soaked in oil. These filters are highly absorbent of dust and are great for vehicles that frequently drive on dirt roads or in off-road motor sports.
  3. Cotton air filters are made of oil-wetted cotton gauze and are better known for high-performance automotive applications such as racing cars.


The auto air filter is usually enclosed in a black plastic casing and is probably the largest non-metal assembly that you see under your hood. Sometimes it is located near the center top of your engine or it could be found to the side in some models. You can easily do a basic air filter change. It only takes a few minutes and will save you money in labor costs.

A clogged air filter could easily cause poor performance, poor fuel mileage and reduced engine life. In addition, it is one of those quick fix tasks that will create a headache of costly engine-related repairs if it is ignored and not replaced regularly. Get in the habit of checking and replacing your car’s air filter with every oil change if you do not want to replace it yourself. If the technician doesn’t automatically check it with your oil change, then ask them to do so.
