What exactly is a car air filter?
In today’s cars, there are four main filters. Cabin filters are made to catch the dust and contaminants in the air before it enters the space occupied by the driver and passengers. The engine oil filter catches impurities, as well as dirt from your car’s motor oil. Fuel filters help clean up fuel so it is free of debris that would otherwise create wear on internal components such as pistons or cams. Air Filters prevent dust and contaminants from getting into your car’s engine.
In this article we will focus on the Air Filter as this is the one most often needing to be replaced by car owners.
The most common type found on cars today are known as “paper” filters which last around 12 -18 months under normal use conditions before needing replacement. These filters are made of cellulose fibers which trap dust and other debris as small as two microns.
How do you know if your air filter needs replacing?
It’s easy to forget about the air filter, but you are putting your engine at risk if it is not replaced or cleaned as recommended by the manufacturer. You might notice issues with fuel economy or power, or unusual sounds. There could also be a misfiring of cylinders when starting the car due to the lack of enough oxygen in the combustion chamber caused by old clogged-up filters.
How to clean your car engine filter
Remove the filter
The air filter is usually located near the engine compartment. Depending on the age, make and model of your vehicle, you may need to open up the housing which may or may not require a screwdriver.
Clean the filter with a vacuum cleaner
Use a small handheld vacuum cleaner to clean the filter. Clean it from both sides and in between pleats if needed. Use a microfibre towel to gently wipe any areas that are still dirty.
Wash in water
Performance air filters such as K&N filters are made to withstand some water. If your filter is of this sort then it will be a sponge or gauze material. If you have this type of filter you can gently wash it in warm soapy water before rinsing and drying. Never use strong detergent because doing either may damage the fibers which keep airflow as smooth and clean as possible.
If you have a standard paper filter and it is looking very dirty, it’s probably time for replacement, especially given the reasonably low cost of new filters.
