In connection with the wildfires in California, Car Care Council has released some tips to help drivers to remain safe in this difficult time.

During wildfires it is expected to encounter soot and smoke which can prove to be a serious issue for both vehicles and passengers. The auto parts that are usually affected are the air filters and cabin filters since these are the parts that gets to trap dirt particles including soot which often damage the engine cylinders, cylinder walls, pistons, piston rings and bearings. The air filter also plays an important role in preventing smoke and soot from polluting the airflow sensor on fuel-injected cars.

Air filters are auto items that calls for regular replacement and checking usually done at each oil change and replaced annually or when it shows signs of contamination. On the other hand the cabin air filter is responsible for screening the air that enters that passenger compartment. Without the wildfires, under the normal circumstances, the cabin air filter traps pollen, bacteria, dust and exhaust gases that finds their way into the vehicle’s ventilation, heating and air-conditioning systems. The filler further prevents bugs, leaves, and other particles from entering the HVAC system which could cause problems.

Of the new domestic and import vehicles sold in the US today, 80 percent are equipped with cabin air filtration systems or if not a slot where one can be fitted. Most filters are accessed through a panel in the HVAC housing which is usually found under the hood or placed within the interior of the vehicle.

Just like air filter, the cabin air filter needs to be replaced instead of simply being cleaned and reinstalled. The cabin air filter must be replaced every 12,000 to 15,000 miles or per the owner’s manual. In areas particularly in areas affected by the wildfires in California where heavy airborne contaminants are present it is important that cabin air filter be changed as often as possible.
