The Cabin Air Filter is a commonly overlooked maintenance item. It's normally checked whenever you bring your vehicle to us for routine maintenance and recommended if needed; yet it's the number one declined recommendation across all six of our dealerships even though it's priced competitively.

The cabin air filter's function is in the name, it filters the air coming into the passenger cabin. Changing your vehicle's cabin air filter can make a big difference on your vehicles overall performance in addition to some health benefits.

Here are the top three reasons you should replace your cabin air filter:

Allergens
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.
Pollution
Pollution is the most commonly cited reason to regularly change out your cabin air filter. Because the filter is basically all that stands between the exterior air of the road and interior air of your car, the filter blocks a lot of the smog and dirty exhaust let out by other vehicles on the road. Regularly changing out your cabin air filter helps ensure these undesirable pollutants don't find their way into your car's cabin.

Reduced Efficiency
When your cabin air filter gets clogged, your air conditioner has to work harder to push cool air through the filter. This can result in a noisy or ineffective air conditioning system. This can be a huge pain during those hot summer months - if your cabin air filter is full of debris and dirt, it'll take way longer for your cabin to cool down. Because your air conditioner or heater has to work harder to cool or heat your car's cabin, your engine has to work harder to power these systems. Surprisingly, having a clogged cabin air filter can actually impact your fuel efficiency because your engine is having to put out more energy than it should.
Most manufacturers recommend replacing the cabin air filter every 12,000 to 15,000 miles. Check your owner's manual for the exact mileage. Many cabin air filters can be difficult to access so it's recommended you have your vehicles service provider replace it for you.
