AMSOIL exclusively offers Absolute Efficiency Ea Air Filters (EaA) with Nanofiber Technology for Automotive and Light Truck Applications
In 2005 AMSOIL INC. of Superior, WI announced the introduction of new premium, high efficiency air filters utilizing nanofiber technology with a four-year/100,000 mile service life guarantee and superior air flow. Positioning itself to be the world class leader in filtration, the AMSOIL Ea Filter remains incomparable in both design and performance: it’s the best in the world, it’s cheapest in use, and it can multiply engine life by three times or more.
In lab testing Ea media with nanofibers removed 5 times more dust than the average cellulose filter and 50 times more dust than the average wet gauze (oiled) media. Ea media also has 3 times the airflow of cellulose filters and is equal to wet gauze filters at the very low 0.5 inches of restriction. The proprietary Ea media held 15 times more dust than the average wet-gauze type oiled filter. In short, AMSOIL Ea Filters offer superior performance in all three of the critical performance benchmarks of efficiency, flow and capacity.
Fast Facts: A nanofiber is less than one micron in diameter. A human hair is 80 microns. A micron is one millionth of a meter, or 1,000 nanometers.
Nanofiber Filter Media – Overview of How It Works
- Traps sub-micron size particles on the nanofiber surface
- Prevents particles from lodging in the filter media depth

|Nanofiber technology has been used exclusively in cleanrooms and heavy duty applications, including the US ARMY Abrams M1 tank. Now AMSOIL has brought this exclusive technology to the auto/light truck market. AMSOIL Ea Air Filters provide the absolute best filtration and include an unmatched 4-year/100,000-mile guarantee. What’s just as surprising as the superior performance? Nanofiber filtration costs less to use: AMSOIL Ea Air Filters save money!

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 cause 50-90% of the engine wear in typical engines.
Wear particles are mostly those between 5 and 25 microns in diameter, and particles smaller than 2 microns do not cause measureable 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.
EaA Nanofiber Filters = Perfection || OEM Filters = Constant Compromise
When they are new, OEM filters are very inefficient and pass many large wear particles. Standard paper and “synthetic fiber” filter technologies immediately begin plugging up because they rely on “depth” filtration and a “dust cake buildup” in order to capture medium and small wear particles. This process of slowly becoming an efficient filter also slowly reduces engine power, efficiency, and fuel economy. Yet when they are able to capture most medium-sized wear particles, the pressure drop across the filter is costing fuel and power.
AMSOIL Ea Air filters avoid both problems to deliver ultimate performance: they provide extreme 100% efficiency at 3 microns when brand new, and when it’s well past time for cleaning they still equal the flow of a brand new OEM filter.
AMSOIL Ea Air Filters also provide greater security than other filters, because recommended service intervals are conservative and performance does not significantly degrade over time. Independent lab testing shows that the filters performed extremely well after 4 cleanings at 5 times the normal particulate loading levels, and still flowed at 99% efficiency after the equivalent of 120,000 miles between cleanings!
EaA filters should be cleaned every year or 25,000 miles, whichever comes first.
Filter Cleaning Instructions:
- Carefully remove filter from the housing. Clean the housing with a shop towel being careful not to knock contaminants into the air inlet.
- Cleaning can be done by two methods:
- Vacuum Cleaning: Place the filter on a flat surface and carefully vacuum the filter media on the dirty side where the incoming airflow enters the filter. Be careful not to rub the filter pleats with the vacuum cleaner attachment too aggressively as this may damage the filter. Using a vacuum with too much suction may damage the filter.
- Shop Air Cleaning: Hold the filter with one hand and carefully blow the filter media at a 45-degree angle on the clean side of the filter using low-pressure (15 to 20 psi) shop air. Be careful not to rub the filter pleats with the air nozzle as this may damage the filter. Using too high of air pressure will damage the filter media.
- Reinstall the filter into the air filter housing and secure.
