Auto Air Filters > About Us
Both cars and people benefit from breathing clean air, and different types
of air cleaners, or air filters, are used to clean and filter the
air that is used by automobile engines and people's lungs. In the
case of the automobile, the air cleaner actually contains an air filter
that removes dust and grit particles from air that enters the internal
combustion engine.
Prior to the 1950s, many automobile engines used oil-bath air intake filters, but today, most automotive air cleaners use disposable, pleated paper filters. These are relatively inexpensive, but they sacrifice good air flow for good filtration. It is important to replace these disposable air filters about every 12,000 miles, or more frequently if you drive in very dusty conditions. Regular air filter replacement can help protect your car's engine, improve gas mileage, and avoid excessive cylinder wear.
Cylindrical air filters were generally used on older cars with carburetor based air intake systems, while flat, rectangular air filters are often used on cars with fuel injection systems. Sometimes, for improved power and efficiency, conical filters and cold air intakes are used to improve the flow of air into the throttle body.
An engine air cleaner typically sits on top of the engine's carburetor,
or near the fuel injection system above the engine. In the latter
case, a large hose connects the air cleaner to the air intake duct.
If the air cleaner's filter becomes clogged with dirt, exhaust emissions
will increase and the engine will run less efficiently. Fortunately,
it is usually a fairly simple task to replace the filter. You will
need a new air filter designed for your vehicle make and model, a clean
cloth, and a basic screwdriver or wrench. Simply undo the clips,
screws, or bolts that hold the air filter cover in place, and remove the
filter cover. If the filter cover is connected to a large hose,
gently move the filter cover and hose aside. Notice how the old
air filter fits into the air cleaner housing, as well as its orientation,
then remove the old filter. Use the clean cloth to carefully remove
any dirt from inside the air cleaner housing, ensuring that no dirt enters
the air intake. Fit the new air filter into the housing, oriented
the same way as the old filter, and reinstall the cover securely, using
the clips, screws, or bolts that you removed earlier. Do not run
your automobile engine without an air filter installed!
