If you do plan to replace it yourself, consider buying a replacement filter at an auto parts store or website to save money. Higher-end cars have more expensive parts, and they might only be available through the dealerships.
If you're having your vehicle serviced at a repair shop or dealership, the technician might recommend a cabin air filter replacement. Before you agree, ask to see your current filter.
You could be surprised to see a filter covered in soot, dirt, leaves, twigs, and other grime, which confirms the replacement service is important. However, if your cabin air filter is clean and free of debris, you can probably wait.
Failing to replace a dirty, clogged filter will impact the efficiency of the heating and cooling system in your car. Poor efficiency can lead to other problems, including a loss of air volume, bad odors in the cabin, or premature failure of HVAC components.
Simply replacing a dirty filter can make a big difference in the car's air quality. You can take additional steps to maintain air quality and prevent other allergens from settling in your car:. A clogged, dirty air filter can cause other issues for both you and your car.
One is a decline in your health, as pollutants can move through the air and cause allergic reactions or breathing problems. A dirty filter can't do its job properly and filter out the contaminants, so it's important to replace the filter in your car frequently. Consider replacing it every year in February before the spring allergy season begins.
While you may not think much of this small service, regular engine air filter replacements are affordable and can save you thousands of dollars in engine damage. This is why a clean engine filter is checked during your annual emissions inspection as well as your annual vehicle inspection. Much like your cabin filter, the cadence of your needed engine air filter replacement depends on your vehicle type. Certain environmental and driving factors can also impact how frequently you need to replace your engine filter.
For drivers who often travel on a dirt road or live in a city with excess pollutants, these hazards could overwhelm your engine filter quickly. You may notice a drop in your fuel efficiency and driving performance as a result of an overdue engine filter replacement. The fuel filter helps to prevent these contaminants from clogging your fuel injectors, thus helping to maintain fuel economy and performance. If a fuel filter becomes clogged, it can cause fuel pressure to drop.
You may also experience issues with starting your vehicle or have a hard time keeping it running. The filters in your car are no exception. At Firestone Complete Auto Care, our expert technicians even check your cabin and engine air filters during a full-service oil change. Any filter — home, auto, or otherwise — will eventually age and become clogged with pollutants and debris. When that happens, it becomes harder for the air or fuel to continue traveling through the filter, which can cause issues.
Eventually the filter media may break, allowing contaminants to reach parts the filter is meant to protect. When your air filter is clogged and heavily restricts airflow, it may lead to incomplete combustion, and ultimately reduced engine power. It can also lead to unwanted, unfiltered air in the cabin.
As for a clogged fuel filter, that can cause a reduction in engine power, low fuel pressure to the injectors, poor acceleration, and lousy fuel economy — not to mention a potential breakdown. The purpose of each filter is clear: to trap and protect. Like a clogged drain, a dirty filter starves the system of vital air or fuel and makes each system it protects work harder to do its job. Once a filter is old and full of crud, you may notice a decline in the performance of that system.
Spot the symptom. Replace the filter. Clogged engine air filters can reduce engine power, decrease throttle response, weaken acceleration, and increase engine wear. How do I know if my cabin air filter needs changing? Reduced air circulation inside your passenger compartment. Diminished heating and air conditioning performance. Musty odor in the cabin of the vehicle. Cabin air intake ducting may begin to make an unusual whistling sound.
How often should I change my cabin air filter? What else can I do to allergy-proof my car? Vacuum seats and carpeted floor mats to remove dust mites. Clean spills quickly to prevent mold from developing.
Wipe down steering wheel, dashboard, console and door panels.
