How Often Change Engine Air Filter ?

Filtration is an important component to the life of a vehicle. Engine air filters remove dirt, dust and other contaminants from the engine intake before it reaches vital engine parts like cylinder walls, pistons and piston rings. 

Air filters help reduce vehicle emissions and burn less fuel . There are three primary filters on a vehicle that protect and optimizes performance. These are Fuel, Oil and Air Filters. The most critical being the air filter. The common types of vehicle air filters are panel and round.

 typical vehicle engine can draw 10,000 gallons of clean air for every gallon of fuel it burns. 

Changing the air filter should be part of a routine maintenance schedule. Show and compare a clean engine air filter to a dirty filter.A clogged engine air filter can hinder the fuel to air ratio needed for the best engine performance.Changing their engine air filter can keep contaminants from damaging vital engine parts. Sluggish performance or loss of engine power is a strong indicator of a need for an air filter change

The Filter Manufacturer's Council recommends inspecting the air filter every time the oil is changed (every three to six months), and replacing every 12,000 miles for preventive maintenance.
Air Filter Construction Materials

A good quality air filter will trap at least 97.5 percent of incoming dirt.

Filter manufacturers use ISO 5011 test procedures to evaluate their air filters, and try to aim for the best balance between filtering efficiency, filter capacity and pressure drop (restriction).

Cheap, low-quality filters are typically less efficient and

may not have as much holding capacity as a quality

brand name filter.

Most of today’s dry paper pleated element air filters

are made of a mixture of cellulose fibers.

Better-quality media in filters are also treated with

resins so they can withstand moisture.

Untreated media in filters may be damaged if rain
