What’s the Most Serious Consequence of Neglecting to Change the Cabin Air Filter?
Beyond Clean Air and Fresh Scents
Today, many brands are selling cabin air filters on the notion that no one wants to spend time in a smelly car if they can help it. The approach makes sense. I think most of us would agree that if a simple filter swap can remedy bad odors in the cabin, we’d be willing to try a change for a reasonable price. It’s an easy problem to solve for customers and their passengers because it’s something they can directly relate to and understand.
Reduced Climate Control Airflow Leads to Unsafe Driving Conditions
But what about the dangers that can’t be seen and the effects that might only be noticed gradually or during certain modes of operation? The reality is that a foul-smelling cabin is not the most pressing problem drivers will face if they never change the cabin air filter or don’t change it frequently enough. Sure, the musty aroma of a wet gym sock with a hint of mildew and a touch of mold would definitely bother me on my daily commute, but a windshield that won’t defog or defrost quickly would be even more prohibitive. Depending on the season or weather conditions, a clogged cabin air filter can be downright dangerous. Suddenly, a clean cabin air filter is less about comfort and more about safety.

Damage to the Car’s Climate Control System
With a clogged cabin air filter, the lack of airflow can be felt at the dashboard vents and will result in lackluster defrosting and defogging performance as well as reduced air conditioning and heating functionality. While these issues can definitely create unsafe driving conditions, there is another problem that customers should be aware of – and that problem is the added stress put on the system’s blower motor. In extreme cases, the clogged filter can completely obstruct the flow of air – either causing the blower motor to fail or suck the filter out of the housing along with all of the debris it’s filtered out. This is the most serious risk for anyone neglecting to change their cabin air filter because the result is acute failure of an important vehicle safety system which will be very expensive to fix.
