A dirty or clogged cabin filter will cause a decrease in the flow of air coming from the vents inside your car. You may also notice the blower motor malfunction or not perform efficiently when the cabin filter is clogged.
A clogged cabin air filter hinders airflow.
Your car's climate control system depends on a clean cabin air filter. When the filter is full of dirt and debris, air cannot flow properly through the system. You'll notice that your windows won't defrost as well if you haven't changed your cabin air filter.
Mold can build up on the filter if you don't change it, which can cause bad odors and smells. Mold is also extremely unhealthy to breathe in, as it can make a person very sick. But by replacing the cabin air filter regularly, you can avoid breathing in that unhealthy mold and keep your cabin smelling fresh.
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.
Believe it or not, your cabin filter can affect your AC system, and the AC can have a strong impact on the power of the entire vehicle. If your filter is clogged, then you might have to turn up the AC. The harder your AC works, the more the engine does, too.
Many cabin filter suppliers recommend a yearly change interval of 12,000-15,000 miles. We recommend adjusting this schedule depending on the region in question and how the vehicle is used. Most often, seasonal changes in the Spring and Fall are appropriate for the cabin air filter.
No, you should never run your AC without a filter!
Although there are specific situations when this may be acceptable for a very short time, in most situations running your AC without a filter could be disastrous. Generally, anytime you run your air conditioning system without an air filter you are taking a major risk.
May cause overheating. Also, a dirty air filter will not be able to provide the oxygen needed to provide a proper air-fuel mix. This can cause the temperature of your engine to rise to dangerous levels. Eventually, your vehicle's engine could overheat which could lead you to the side of the road.
Dirty Air Filter Symptoms
Engine misfires and violent vibrations can be caused by an air filter that is dirty and clogged. The clogged air filter may allow oil to burn improperly, thus contaminating the spark plugs of your engine with excess oil deposits.
A dirty engine air filter can cause your engine to run poorly, and contaminants that pass by it can cause wear inside your engine. A bad cabin air filter usually won't cause damage, but it can prevent you from operating your car safely.
An extremely dirty air filter restricts engine air intake. This disrupts the air/fuel mixture inside the engine. As a result, the vehicle may experience performance problems that trigger the check engine light.
If the cabin air filter is excessively clogged, it can restrict airflow to the engine compartment, affecting the combustion process. Reduced airflow may lead to inefficient fuel burning, which can result in decreased power output and sluggish acceleration.
Cabin Air Filters Make a Difference in Three Important Areas
Having a super dirty cabin air filter can decrease your vehicle's air-conditioning, make your engine work harder, and can even reduce the amount of clean air that you breathe while driving.
Besides causing foul odor as mentioned earlier, an unclean cabin air filter with mold and mildew can make you sick. Plus, since the filter can't trap more particles like dust and pollen, you end up breathing unfiltered air in your car, which can worsen allergies and respiratory problems.
Most manufacturers recommend a replacement every 15,000 to 30,000 miles under normal operating conditions. A cabin air filter does not have a specific service life, since cars operate at different intensities, and you should change it as needed.
In addition to affecting air quality, a dirty cabin air filter can also affect the performance of the vehicle's heating and air conditioning system. The system must work harder to circulate air when the filter is clogged, which can lead to reduced efficiency and increased strain on the system.
First, check your filters and coils for dirt and debris that may be impeding airflow. Once you've cleaned the filters and coils, run the air conditioner with just the fan so that the ice accumulation can melt off. If the AC still doesn't blow cold air, it could be that refrigerant levels are too low.
The answer depends on your vehicle's make, model, and year, but generally, you should replace the cabin air filter every 15,000-30,000 miles. You can find your vehicle's recommended interval in your owner's manual. To find the specific recommendation for your vehicle, you should reference your owner's manual.
If you take your vehicle to your dealer for service, they will likely replace the air cabin filter with a manufacturer-approved version that can run from around $40 to upwards of $100. If you replace the filter yourself, it can be as affordable as $18 to $28.
How do you know if your cabin air filter is bad? Decreased airflow from the vents, bad smells in your car, and trouble clearing a foggy windshield indicate your cabin air filter is bad.
Changing your vehicle's cabin air filter can make a big difference on your vehicles overall performance in addition to some health benefits. Cabin air filters help drastically reduce the amount of allergens that can get into your vehicle.
