Cabin Air Filter Replacement

What is a Cabin Air Filter?

A cabin air filter, also known as an AC filter, is a component found in many modern vehicles. It is located in the HVAC (heating, ventilation, and air conditioning) system and serves to filter the air that enters the interior cabin of the car. The primary function of a cabin air filter is to trap and remove airborne particles such as dust, pollen, allergens, pollutants, and even some odors. It helps improve the air quality inside the vehicle by preventing these contaminants from entering and circulating in the cabin, providing a cleaner and more comfortable environment for the occupants. Regularly replacing the cabin air filter is essential to maintain optimal air filtration and ensure efficient HVAC system performance.

Cabin Air Filter vs Engine Air Filter

Every vehicle in New Hampshire and Maine has an engine air filter that cleans the air going into the engine, but not all have a cabin air filter that cleans the air going into the passenger compartment. Easy to get mixed up. The cabin air filter cleans out dust, pollen, spores and other pollutants. To give a point of comparison, a grain of sand is about 200 microns across. A cabin air filter can stop particles that are just 3 microns in size. It really does make the passenger cabin a much more pleasant environment.

When the cabin air filter gets dirty, you just need to replace it. Your owner’s manual may have a recommended interval for changing it. If not we can inspect it. You know, it’s ironic that many people who don’t realize they even have a cabin air filter first find out they do when it starts to get smelly.

 Some cabin air filters are very easy to access when it’s time to replace them. Others, not so much. We may have to get behind the dashboard and it takes some time. A clean cabin air filter keeps out smog, allergens and other harmful pollutants. If it’s time, get it changed right away.

DID YOU KNOW?

The air inside your vehicle may actually be more polluted than the air outside. Pollen, mold, dust, etc. can be trapped inside your vehicle. The cabin air filter stops these pollutants before they even get inside and filters out odors and smoke. People who suffer from seasonal allergies really appreciate a clean cabin air filter.
