Essential Filter Replacement
Keep your engine and cabin air clean with our trusted filter inspection and replacement.
Engine & Cabin Air Filter Service
Clean air filters are vital for your vehicle's health and your comfort. The engine air filter protects your motor from abrasive dirt and debris; a clogged filter restricts airflow, reducing power and fuel economy. The cabin air filter cleans the air you breathe inside the car, trapping pollen, dust, and other allergens. We check these filters regularly and replace them when they become dirty. Using high-grade filters ensures optimal performance and protection. It's a simple maintenance with significant benefits for your engine and your health.

Why Filter Quality Matters
Not all filters are created equal. Cheap filters may use less effective filtering media or flimsy frames that can collapse. We use premium filters that offer superior filtration efficiency without excessively restricting airflow. A high-premium engine air filter captures more harmful particles while allowing your engine to breathe freely. A good cabin filter improves your HVAC system's airflow and does a better job of removing odors and pollutants from the cabin. Don't compromise on protection; we use the best filters for your vehicle.
Signs Your Filters Need Replacing
For the engine air filter, a loss of power or reduced gas mileage can be a sign it's clogged. visually, it will look dirty and caked with debris. For the cabin air filter, you might notice reduced airflow from the vents, musty odors, or increased allergy symptoms while driving. We recommend inspection at least once a year, or more often if you drive in dusty conditions. Our Novato crew will show you the filter and recommend replacement only when it's truly needed.
