Ever noticed a musty smell when you turn on your car’s A/C or felt like the airflow just isn’t what it used to be? It’s easy to blame the weather or dust outside, but chances are, you need a Cabin Air Filter Inspection and Replacement. This filter removes dust, pollen, dirt, smog, and even mold spores before they reach the air inside your car. It also helps protect your HVAC system from getting clogged with debris. When it’s clean, it keeps the air fresh and your system running efficiently. But when it’s dirty? It can reduce airflow, make your car smell funky, strain your A/C system, and even affect fuel efficiency.

One of the biggest issues with clogged filters is how easily they go unnoticed. Since the filter is out of sight, many drivers don’t realize it needs attention until symptoms start creeping in unpleasant odors, foggy windows that won’t clear up, or allergies that seem worse when you’re driving. These are all signs that your filter may be due for an inspection. Another important but lesser-known impact of a dirty cabin filter is how it affects your engine indirectly. When airflow is restricted, your car’s ventilation system has to work harder to push air through. That extra strain can reduce the efficiency of the entire system, including how hard your engine has to work to support it. That means more fuel consumption and, over time, more wear on your engine.

So, how often should you get a Cabin Air Filter Inspection and Replacement? It depends on your driving conditions, but a good rule of thumb is every 15,000 to 20,000 miles or once a year if you drive frequently in urban areas, dusty environments, or during allergy seasons. If you’ve never had it checked or can’t remember when it was last replaced, there’s a good chance it’s time. At Multnomah Automotive, we don’t just swap out your filter and call it a day.
