Of course, the most noticeable problem with a missing cabin filter is the air quality. You will be breathing in all of the contaminants spewed by other vehicles on the road, like diesel fumes and burning oil. Allergens also make its way in and won't be scrubbed before being circulated through the cabin.
You should not run without the cabin air filter. Not only does it prevent all those particles from being breathed in by you and your passengers, but it also prevents particles from getting into and damaging the fan and ducting mechanisms in your HVAC system.
Cabin air filters help drastically reduce the amount of allergens that can get into your vehicle. Pollen could easily get into your vehicle without the cabin air filter, and the less often you change your filter, the more pollen that will build up, which could cause more of it to get into your vehicle.
All vehicles will have an engine air filter, while many (but not all) newer cars have a cabin air filter. Check your owner's manual to find out. The cabin air filter plays a crucial role in your car's heating, ventilation, and air conditioning (HVAC) system.
Driving without an air filter will let more fine dust in to the engine. This makes the engine wear out a bit faster than it normally would. The more you drive through super dusty or sandy areas, the more harmful it is.
Cabin air filters stop debris from getting in the blower motor housing, and they remove pollen, dust, and toxins from the air. Without the filter installed, dirt can build up on the blades of the fan and inside the motor housing. This can overheat the unit and knock the fan off balance.
No, you should never run your AC without a filter!
The purpose of your air filter is to clean your home's air and to keep your AC system dust- and dirt-free, which is why it's important to only run your AC with a filter installed.
Just like how a low fan speed on a hot day will never make you feel cold enough, a clogged cabin air filter restricts airflow, which can make your AC seem less effective. So, while a new cabin air filter might not make your AC 'colder,' it certainly contributes to a cooler and more comfortable cabin experience.
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.
First introduced in the mid-1980's in European automobiles, cabin air filters appeared in North American automobiles in 1994.
Of course, the most noticeable problem with a missing cabin filter is the air quality. You will be breathing in all of the contaminants spewed by other vehicles on the road, like diesel fumes and burning oil. Allergens also make its way in and won't be scrubbed before being circulated through the cabin.
Expensive air filters are made from higher-quality materials, like fiberglass, that can last for up to 12 months.
You might wonder about the risks of running your AC without a filter, even temporarily. The simple answer is: not for long. Ideally, your AC should never operate without a filter for more than 6-8 hours. Going beyond this can negatively affect both your system's health and your home's air quality.
Cabin air filters can capture dust, bugs, leaves, and other various types of debris. A dirty air filter can certainly impede your air conditioner's ability to cool and after time could cause unnecessary strain on the entire system. Another common potential reason is that your compressor has failed.
While you can run a car without a cabin air filter, it's still important to replace it.
If you don't change your filter, you'll run into problems down the road. Why should I care if my filter is full? A dirty, old cabin air filter can have a negative effect on your vehicle. When your cabin air filter is clogged, airflow is restricted.
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.
If you breathe in air that has not been filtered or is filtered through a dirty cabin air filter, you may notice that you get sick more often, have difficulty taking deep breaths, and have allergies that are exacerbated. Your car's health may be at risk, too.
One of the most common culprits behind an A/C system blowing warm air is a low refrigerant level. Refrigerant is responsible for absorbing heat from the cabin and releasing it outside, creating cool air. Over time, your car's A/C system may develop leaks, resulting in a loss of refrigerant.
Does a Cabin Air Filter Affect Gas Mileage? If you find that your car's filter is clogged, it can actually affect how efficiently fuel burns because of the increased pressure needed to push air through an obstructed system. This means more work for your engine and less efficiency in powering wheels!
As a result, the air inside the vehicle can become polluted, which can trigger allergies or other respiratory problems for passengers. 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.
Without a functional air filter, dirt and debris can easily enter the turbocharger, causing extreme damage. To make things worse, metal from the failed turbocharger can find its way into the engine, circulating throughout the system. This can result in complete engine failure.
But when the filter wears down and gets dirty, it can choke off your car's air flow and hurt your engine's acceleration power. If you've noticed slower acceleration or other issues with your vehicle's performance lately, replacing the air filter could be the answer.
