AMSOIL Ea™ Air Filters

Air Filter Basics

An engine needs air in order for combustion to occur, but the air drawn in through the induction system is loaded with contaminants. There are over 400 tons of suspended dirt and other contaminants in a cubic mile of air over a typical city. The dirt and contaminants drawn into an engine are the leading cause of engine wear.
     The air filter is the first line of defense against the abrasive airborne grit that can cause engine damage. But in order to do the job right, an air filter must effectively filter the dangerous particles out of incoming air without obstructing the vital flow of air to the engine. As the filter traps more and more contaminants, air flow becomes restricted, smothering the engine and diminishing performance. The more wear-causing contaminants a filtration media traps and the more contaminants the filtration media holds, while still allowing optimum air flow, the better the filtration media is.

Revolutionary Technology

Nanofiber technology has been used exclusively in heavy-duty applications, including the US ARMY Abrams M1 tank. AMSOIL has brought this technology to the auto/light truck market. Nanofiber is a phrase generally referring to a fiber with a diameter less than one micron. The revolutionary nanofiber technology used in AMSOIL Ea™ Air Filters surpasses all other technology, capturing more dirt, holding more dirt, and allowing better air flow and a longer service life than conventional air filters.
     Here's how it works: Imagine two filtration media, a chain link fence and a mosquito net. Each is required to stop contaminants, in this case tennis balls. A tennis ball will fit quite nicely into an opening of a chain link fence, but will obstruct the hole almost 100 percent. Now, imagine a tennis ball covering a mosquito net. The tennis ball, at the point of contact with the netting, will obstruct much less filter area than the chain link fence example. In fact, air will flow around the tennis ball all the way to the point of contact. It will take many more particles to obstruct the netting surface area than the chain link fence.

Proper air flow is vital to maximize performance and engine life. Air is required to release the energy from the fuel being used. It takes 1,200 cubic feet of air to combust one gallon of gasoline. Inadequate air flow can cause serious loss of power, poor performance and excessive fuel consumption. Tests show that AMSOIL Ea™ Air Filters have more than three times the air flow of filters that use cellulose media alone, for increased performance and fuel economy. Although the wet gauze filter provided slightly better air flow, it allowed a lot more dirt to flow through and it didn't have anywhere near the dirt-holding capacity, as you can see on the graphs above.

As shown in the photo, cellulose fibers are larger than nanofibers and have larger spaces between the fibers, causing the contaminants to load inside the depth of the media and plug the airflow path, resulting in higher restriction and less capacity.
AMSOIL Ea™ Air Filters allow more airflow than filters that use cellulose media alone. The synthetic nanofibers in the Ea™ filter media have submicron diameters and small interfiber spaces, which result in more contaminants being captured on the surface of the media and less air restriction.

Cleanable - Longer Life

When cleaned according to AMSOIL specifications and used in normal service, AMSOIL Ea™ Air Filters are guaranteed for 100,000 miles or four years, whichever comes first. AMSOIL Ea™ Air Filters remain effective for 25,000 miles or one year before requiring cleaning. This coincides with the AMSOIL 25,000-mile/one-year motor oil drain interval, adding even more convenience for motorists by consolidating routine maintenance. (See below for cleaning instructions.)

Saves Money - Good for the Environment

Buying an AMSOIL Ea™ Air Filter makes good old-fashioned dollar sense because it will save you money. It is easily cleaned and reused and is designed for years of dependable service. As you can see on the chart below, one AMSOIL Ea™ Air Filter costs only slightly more than conventional cellulose air filters, but it lasts eight times times longer. Conventional cellulose filters must be thrown away and replaced every six months, which is quite costly. Over a four-year period, an AMSOIL Ea™ Air Filter can save you as much as 424%! And, not only does an AMSOIL Ea™ Air Filter pay for itself, there are also fewer dirty air filters to throw away, which is better for the environment! See the savings below:
