A Look at Amsoils air filters.

[Ridin' Around]

AMSOIL Ea Air Filters represent a major breakthrough in filtration technology. For the first time, revolutionary nanofiber technology is available to the auto/light truck market. Nanofiber technology has been used exclusively in heavyduty 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 for AMSOIL customers and with an unmatched four-year/100,000-mile guarantee, AMSOIL Ea Air Filters save money!



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 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.


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%.
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.


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 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 on top of 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.



Efficiency is the ability of a filter to stop dirt and other airborne comtaminants 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 filters.



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.


The filters are available as both drop-in filters for OEM replacement & as cone styles which can be used on your favorite aftermarket intake set-up.

*Please note that anywhere a "wet guaze" or "oiled guaze" filter is mentioned they are talking about filters like the K&N brand.

Bump to the Top

[JDePietro]

I can't find any customer reviews, so I'm a little hesitant to drop 47.50 on a filter.

Is anybody running one of these? I get the concept but honestly I'm a little more catutious since falling for the K&N hype.

Do you offer any kind of discount for forum members?

trust me i got one it's great you just blow them out with air no oiling

the K&N's make your throttle body sticky.

drop me an Email & I will get you a wholesale price.

There are alot of guys running these. I will see if we can get a few guys to chime in here.

Efficiency is the ability of a filter to stop dirt and other airborne comtaminants 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 filters.

Seems like someone is trying to re-invent the definition of efficiency.

If something stops more dirt from entering the engine, it doesn' make it more efficient.

Some of the phrases sound a lot more like marketing hype than actually factual statements.

"if a filter is more efficient, that means it has the ability to pass more air through to the engine, even when it starts to get dirty"

[Ridin' Around]

There is a little more to it than making it just that simple. Here is what is commonly found on air filter efficiency. While this example applies to HVAC air filters, it still explains the idea well.

Efficiency and arrestance are commonly used to describe air filters functionality.
Air Filter Efficiency

The ability of a device to remove particulate or gaseous material from an airstream by measuring the concentration of the material upstream and downstream of the device.
The efficiency describes how well of an air filter removes microscopic particles such as dust, dust mites, pollen, mold, bacteria, and smoke.
In the ASHRAE 52.1 Standard test method, efficiency is a measure of the ability of a filter to remove the staining portion of atmospheric dust from the test air - officially termed "Atmospheric Dust Spot Efficiency".


Air filter efficiency can be expressed as

μ_e = n_t / n_u = (n_u - n_d) / n_u (1)

where

μ_e = air filter efficiency

n_t = particles trapped

n_u = particles upstream

n_d = particles downstream

Air Filter Arrestance

A measure of the ability if an air filtration device to remove synthetic dust from the air.
The arrestance describes how well an air filter removes larger particles such as dirt, lint, hair, and dust. ASHRAE arrestance is a measure of the ability of a device to remove ASHRAE dust from test air.
The dust holding capacity of a filter is the amount by weight of standard dust that the filter will hold without exceeding the resistance 0.18 in W.G. for low-resistance filters, 0.50 in W.G. for medium-resistance filters and 1.0 in W.G. for high-resistance filters.


Dust arrestance can be expressed as

μ_a = 1 - C_a / C_b (2)

where

μ_a = dust arrestance

C_a = dust concentration after filter

C_b = dust concentration before filter

The efficiency of a filter is an indication of how well it filters over time. Can it trap dirt & still let air pass? or is it clogged in 100 miles? there is alot to it.

I assume that these are one time use filters, not the wash and re-use type?

[CLNinja]

these are reusable filters , they are just not oiled like K&N filters


i have one of these on my Jeep and love it

when i clean it i either just blow it out with an air compressor... or hose it off and then blow it out

i highly recommend the amsoil air filters

[ZJones]

I've got one in my jeep as well. It's been great so far!

[Ridin' Around]

The official lifetime of the Filter from Amsoil is 4 years or 100,000 miles, whichever comes 1st.

To clean you can use a shop vac to suck out debris or low pressure compressed air to blow it clean. No waiting for it to dry or worrying if it is oiled correctly.
