How do Air Filters Work?

Chentai is a industrial filter media manufacturer. Which share you the work of air filters.

Air filters work by trapping some of the small particles that exist in most environments while allowing air to flow relatively unimpeded. In an automotive intake system, the air filter always sits ahead of the throttle body and mass air flow sensor.

In older applications, the air filter typically sat directly on top of the carburetor. In newer applications, air filters are typically installed in “air filter boxes” at the head end of the intake system. In those cases, the air inlet may be located on the box, or there may be a tube that leads from the box to the front of the engine compartment.

When air first enters the intake system, it has to pass through the air filter. As it passes through the filtration media, any particulate matter larger than the pores in the filter gets stuck, while the air itself is able to pass through. This causes a certain level of restriction on the flow of air, but it is typically negligible when the filter is relatively clean.

Without an air filter, particulate matter would be able to enter the throttle body and pass into the combustion chambers. Depending on the amount of particulate matter in the air, this could potentially cause damage to the engine or various components. In that way, an air filter “sacrifices” itself to protect the engine. Over time, the filter will gradually become clogged up, and it will eventually have to be cleaned or replaced (depending on what type of filter it is.)
