What does an air filter do?

An air filter helps your engine run smoothly. It does this by intercepting tiny particles like dust and dirt before they reach your engine. This helps your engine run efficiently, as these particles can cause damage if not trapped. A clean air filter also ensures the optimal amount of clean air mixes with your fuel. This enhances engine performance and fuel efficiency.

How often should you replace your air filter?

How often you change your air filter depends on your car. Usually, manufacturers recommend replacing them in an annual service or every 12,000-15,000 miles—whichever comes first. If you’re unsure, check your vehicle’s manual for specific recommendations. You can also check the air filter to see if it’s visibly dirty. If it is, it’s a wise idea to replace it. Regular replacement helps keep your engine running smoothly.

Pollen Filter

Often referred to as a cabin filter, a pollen filter cleans the air that enters your car’s interior through the heating, ventilation, and air conditioning (HCAV) system. You can find your pollen filter inside the passenger compartment, often behind the glove compartment.

Other filters

  • Oil Filter: An oil filter removes things that contaminate your engine oil, such as air, water, fuel, soot and other impurities. Oil filters are typically mounted on the engine block.
  • Fuel Filter: The fuel filter cleans the fuel before it reaches the engine, preventing dirt and debris from causing damage to the fuel injection system. They’re located in the fuel line, either in the engine compartment or along the chassis.
