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.
First, you will likely be too hot or too cold. If you own a vehicle manufactured in the past decade, your onboard computer will try to compensate for the lack of an air filter by altering the power supplied to the fans, but that can reduce the lifespan of the entire climate control system.
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.
The cabin air filter is an essential component of your vehicle's ventilation system. It is responsible for getting rid of a variety of pollutants from the air which comes in through the ventilation system and circulates throughout the cabin.
On average, you should change your cabin air filter every 15,000 miles, however, we recommend consulting your owner's manual to be sure.
Neglecting your air filter can lead to several issues. Over time, it can cause reduced fuel efficiency, diminished horsepower, and even engine damage. Keeping up with this small maintenance task can save you from more significant, expensive problems.
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.
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.
Expensive air filters are made from higher-quality materials, like fiberglass, that can last for up to 12 months.
Effect on Engine Performance
While the cabin air filter's primary function is to protect the air inside your vehicle, its condition can indirectly affect engine performance. A clogged filter can lead to increased pressure within the HVAC system, which can put additional strain on the engine.
The first known OE cabin air filter was used on a Rambler in the 1970s, but the first ones to become a significant factor were on European luxury cars, particularly BMW and Mercedes in the late '80s.
Unlike engine air filters, there are no true performance gains to be found when moving from one brand of cabin air filter to another. Keeping your climate control system clean is a relatively simple job, and a basic filter typically gets the job done.
No, running your AC without a filter is not recommended and is generally dangerous to the health of your air conditioner. Any amount of time that an air conditioner is run without a filter could cause damage to the system and shorten its life span. It is best to get a replacement filter as fast as possible.
While cleaning may extend the filter's life slightly, it does not restore the material to its optimal condition. Replacing your cabin air filter ensures you have a fresh, efficient barrier against contaminants, improving air quality and vehicle performance.
If the filter is too small, it won't cover the entire space and may allow dust and dirt to flow past. If you're not sure what size filter you need, check the manufacturer's specifications or ask your HVAC technician for help choosing the right product.
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.
Can I run my car without a cabin air filter? While you can run a car without a cabin air filter, it's still important to replace it.
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.
Most cabin air filters can be replaced in less than 15 minutes without tools, although some take a little longer and may require removing fasteners that hold the glove box or interior trim panels in place. If you need help replacing your filter, check with your local auto repair shop.
When Should I Change My Cabin Air Filter. The rule of thumb for how often to change cabin air filters is every 15,000 miles. Some Purchase drivers encounter scenarios where their air filter works harder such as when going off-roading or when driving in locations with dirt or gravel roads.
Cleaning the air filter only improves its appearance. When should an air filter be replaced? The air filter should be replaced after the period indicated by the vehicle manufacturer.
Most cars are designed to last between 150,000 to 200,000 miles.
