Revolutionary Technology
Nanofiber is a phrase generally referring to a fiber with a diameter less than one micron. Cellulose fibers, on the other hand, are larger than nanofibers and have larger spaces between the fibers, causing contaminants to load in the depth of the media and plug the airflow path, resulting in higher restriction and less capacity.

AMSOIL Ea Air filters incorporate a specially constructed cellulose media with exclusive synthetic nanofibers applied to the surface. Dust and submicron particles are trapped on the nanofiber surface, preventing them from lodging in the filter media depth.

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.

Above: AMSOIL Ea Air Filters have more than three times the airflow of cellulose. Both wet gauze and Ea are below 0.5 inches of initial restriction.

Above: AMSOIL Ea Air Filters hold 15 times more dust than a wet gauze type filter.

Above: AMSOIL Ea Air Filter media removes 5 times more dust than traditional cellulose filters and 50 times more dust than wet gauze.

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 concentration can be even higher in rural areas where there is frequent travel on unpaved roads. The dirt and contaminants drawn into an engine are the leading cause of engine wear.

The function of the air filter is to trap and hold these wear causing contaminants without restricting air flow. 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.

The new nanofiber technology used in AMSOIL Ea filters surpasses all other technology in efficiency, capacity and service life. With AMSOIL Ea Air Filters, dust and submicron particles remain on the surface and are trapped in the nanofibers, preventing particles from lodging in the filter media depth. This produces higher efficiency and higher capacity which extends engine and filter life and reduces engine wear.

Ea Air Filters Capture More Dirt
Efficiency is the ability of a filter to stop dirt and other airborne contaminants from entering the engine. The more efficient a filter is, the more dirt and contaminants
it stops. Extensive testing proves that AMSOIL Ea Air Filters are more efficient than cellulose and wet gauze air filters.

Allows More Air Flow
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 airflow of filters that use cellulose media alone.

Holds More Dirt
A filter’s ability to contain trapped contaminants determines how well an engine will run and how long the filter will remain effective. If the capacity is too low, the filter will have to be replaced constantly. When the filter is full, air cannot pass through at the rate necessary for proper engine performance.

AMSOIL Ea Air Filters hold up to five times more contaminants than cellulose air filters. Since the nanofibers in the media are so small there are more pores per square inch, allowing for higher dirt-holding capacity and lower pressure drop when compared to cellulose filter media alone. Thinner media fibers produce more uniform pore size distribution, improving the filter’s overall quality and ability to capture and retain particles. Testing shows that Ea Air Filters hold 15 times more contaminants than a wet gauze type filter. The capacity is so great, in fact, that the new AMSOIL Ea Air Filters remain effective for a full 25,000 miles or one year before 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.

Synthetic media have submicron diameters (nanofibers) and small inter-fiber spaces which result in more contaminants being captured on the surface of the media and lower restriction. Cellulose fibers are larger and have larger spaces between the fibers, causing the contaminants to load inside the media and plug the flow path, resulting in higher restriction and lower capacity. Why does the AMSOIL EaO Filter use wire mesh? The synthetic media needs support. Will the AMSOIL EaO Filters remove soot? AMSOIL EaO Filters were designed to meet the filtration needs post EGR engine development. However, these are full-flow filters and are not designed as a soot control device. How long do Ea Oil Filters last? EaO Filters are guaranteed for 25,000 miles or one year, whichever comes first, when used in conjunction with AMSOIL Synthetic Motor Oil. AMSOIL recommends changing the oil filter at the time of oil change. Can I still purchase AMSOIL SDF Filters? AMSOIL SDF Filters will be available while supplies last. They are no longer available for online purchase. Why are the SDF Filters being phased out? AMSOIL is continually searching for new and innovative technologies to enhance its product line. With the advent of the nanofiber filtration media, AMSOIL desired to be on the cutting edge and provide the most innovative oil filter technology in the auto/light truck market. Will SDF Filter warranties still be honored? Yes, if an SDF Filter is deemed defective in accordance with the AMSOIL filter warranty, AMSOIL will replace the defective SDF filter with a comparable EaO filter or will credit the customer’s or Dealer’s account for the purchase price of the SDF filter. What is AMSOIL’s filter warranty? AMSOIL warrants that its filtration products are fit for use according to AMSOIL’s recommendations and warrants its products to be free of defective materials, design and workmanship. What kind of vehicles are the AMSOIL EaO Filters designed for? AMSOIL EaO Filters are designed for cars and light trucks equipped with gasoline engines and some diesel pickups.
