Most vehicles have two types of air filters: cabin air filters and engine air filters. Your cabin air filter is very similar to the air filter in your home, supplying clean air to the inside of your vehicle. If you notice bad quality air or low air pressure when you turn on the A/C, it may be time for a new cabin air filter.
Your vehicle also has an engine air filter. This air filter supplies clean outside air to your engine to make the combustion process possible. A dirty engine air filter means that less air can get to the engine. Most times it is better to go to the professionals at auto repair mesa az if you fear your vehicle has a dirty engine. Reduced airflow decreases your engine power and even lead to poor fuel economy in extreme cases because the engine has to work harder.
While it varies from vehicle to vehicle, you should usually replace your engine air filter every 20,000 – 30,000 miles or every 2 – 3 years for average driving conditions. However, if you live in a polluted area or often drive in dustier conditions, your engine air filter may need to be replaced more often.
Some oil shops will try and convince you that your engine air filter should get replaced with every oil change. While this is often extremely excessive, it’s not a bad idea to check your engine air filter every time you do an oil change. Your owner’s manual will tell you the location of both your cabin air filter and your engine air filter.
If your engine air filter appears clogged to the point where less air can pass through, or you notice a lot of debris, it may be a good time to change your oil filter.
All auto parts stores carry both cabin and engine air filters. A guide is typically included that allows you to look up the make and model of your vehicle to determine what filters you need, or you can ask a clerk. Some dealerships will allow you to order factory replacement air filters. If you’re looking to save some money you could always look at filter prices online. If your driving conditions require more frequent filter changes, you may be able to find deals on bulk filters on eBay, Amazon, or specialty online car part retailers. Always remember to double check that the filter you are purchasing is compatible with your vehicle.
