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. AMSOIL Ea Air Filters provide the absolute
best filtration and with an unmatched
4-year/100,000-mile guarantee, AMSOIL Ea Air Filters
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
Hereís how it works: Imagine two
filtration media, a chain link fence and a mosquito net.
Each is required to stop contaminants, in this case
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

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
it stops. Extensive testing proves that AMSOIL Ea Air
Filters are more efficient than cellulose and wet gauze
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 filterís 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 filterís 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 filters should be cleaned every
year or 25,000 miles, whichever comes first.
- Carefully remove filter from the
housing. Clean the housing with a shop towel being
careful not to knock contaminants into the air
- Cleaning can be done by two
- 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.
