🌬️ Cabin Air Filters: Breathe Cleaner Inside Your Car

When was the last time you changed your cabin air filter? If you're not sure, you're not alone—but it might be affecting your health and your car's performance more than you think.

A cabin air filter plays a crucial role in maintaining the air quality inside your vehicle. It traps dust, pollen, dirt, smog, and even bacteria before they can enter through your HVAC (heating, ventilation, and air conditioning) system. Whether you’re stuck in traffic or driving through the countryside, a clean cabin air filter helps ensure you're breathing cleaner air.

Why You Should Replace Your Cabin Air Filter Regularly

Most car manufacturers recommend replacing your cabin air filter every 12,000 to 15,000 miles, but this can vary based on driving conditions. If you frequently drive in heavy traffic, urban areas, or dusty environments, you may need to replace it more often.

Common signs your cabin air filter needs replacing:

  • Reduced airflow from vents

  • Unpleasant or musty odors

  • Increased allergy symptoms while driving

  • Foggy windows or decreased HVAC performance

Replacing your cabin air filter is one of the easiest and most affordable ways to improve air quality inside your vehicle and keep your HVAC system running efficiently.
