What is Climate Control Air Filter and How to Replace It

The cabin air filter is a small pleated filter made of multi-fiber paper cotton or other engineering material. It is designed to trap contaminants before they enter the passenger compartment of your vehicle. This filter is usually located behind the glove compartment and cleans the air as it moves through the vehicle's HVAC system. A cabin air filter helps remove harmful contaminants, such as pollen and dust, from the air you breathe inside the car. If you notice that your car has an unpleasant odor or that airflow has decreased, consider replacing the cabin filter to give the system and yourself a breath of fresh air.

A cabin air filter is an integral part of all modern vehicle climate control systems. They are visually similar to engine air filters and, like engine air filters, cabin air filters are sized based on the volume of air they must filter for efficient operation. Incoming air cools as it is forced onto the evaporator core and, as it cools, moisture is removed from the air. Continuous updates to the filter and activation media have resulted in the newest cabin air filters being able to remove even the smallest physical and irritating particles, filtering particles down to ≥2 microns. This is especially useful for the “maximum” setting for the air conditioning, because the air being used is already close to the desired temperature, which makes it easier for the air conditioning system to work.

These are literally systems that have replaceable scent cartridges that allow the driver to choose a fragrance to add to the cabin air for a new individualized in-car air quality experience. It also gives you peace of mind knowing that you and your passengers receive properly filtered air in a world that is constantly filled with additional harmful pollutants. This position near the base of the windshield is also an area of high air pressure, which means there is always an abundant supply of fresh air for the system to use. Recirculated air means that the air that is already inside the cabin is used as the primary source of air for your HVAC system. The air conditioner air cleaner installed inside the engine room compartment filters dust or other contaminants entering the vehicle from the outside through the heating and air conditioning system. If your air conditioner doesn't blow cold and you've done the maintenance we mentioned above, it may be time to seek professional help.

The best time to do this is when you perform the annual cabin air filter replacement, saving you time and effort accessing this part of the system. Some cars during that period were even manufactured with a location for a cabin air filter, but were not factory installed. From there, air is sent through the blower motor, which dictates how much air is drawn from the fresh air vent, as well as the strength of the air exiting the vents inside the car. Throughout the 1990s, cabin air filters became increasingly common across multiple makes and models, but it wasn't until the early 2000s that nearly every car in the U. S.

UU. were delivered with a factory one. The cabin air cleaner is usually installed in the heater box, which is located under the dash, usually near the firewall or the passenger side footwell area. It's a fairly easy and straightforward process to inspect and replace the cabin air filter on most vehicles. Replacing your car's cabin air filter regularly can help keep your car's interior smelling fresh and clean while also improving its performance. It's important to check your owner's manual for specific instructions on how to replace your car's cabin air filter.

If you're not sure how to do it yourself, you can always take your car to a professional mechanic who can do it for you.
