Green Filters started in the business by crafting custom filters for the motorsports industry, with clients who had very high demands. A racing filter has flow air like an open storm door, even when it has collected dirt from the racetrack for an entire 24 hour endurance race, or a thousand miles of Baja. Expanding the product line into street vehicles gave the company a lot of happy customers who have changed over to Green Filters from their stock unit. And the attributes that make a great race filter apply to street cars as well.
The basis of Green Filters technology is an oiled, woven cotton element. Why low-tech cotton in a high-tech racing car? Wouldn't the cotton gauze used in other aftermarket filters perform better and have less restriction than cotton cloth? Nope. Woven cotton is thinner, holds oil better, and is stronger. Since it's thinner, it has superior air flow without sacrificing filtration. Woven cotton distributes oil more evenly, and the medium is much stronger. Unlike gauze, you can't wear a hole in woven cotton by rubbing it, and there is no way small bits of cotton can rip off since it's interlocked with another piece. Crossing one fine and one medium layer produces a fabric that is thinner and stronger than other materials and has the ability to trap dirt down to 5 microns. The result: better airflow without sacrificing filtration. And because the fabric is so durable, the filters can be washed and reused over and over, which allows Green Filter to give a lifetime guarantee.

This superior cotton fabric sandwich is armored with steel mesh, not aluminum, for better strength and durability. A casual knock from careless handling during cleaning won't dent the mesh like it would aluminum. The weight penalty is minor, but the lifespan of the filter element should now be longer than the lifespan of the car or truck it's installed in. The use of steel also permits the pleats to be deeper for maximum surface area, which reduces flow restriction and lengthens the interval between cleanings.
Consider something as simple as the rubber molding that surrounds the mesh. Other filter manufacturers use a pressure injection-molding process, similar to the process used to mold the rubber onto OEM-style paper filters. This is faster, but allows a lot of rubber to creep onto the filter medium instead of staying around the perimeter like it's supposed to. This can block as much as 25% of the airflow in some applications. Green Filters doesn't inject all the rubber at one fell swoop, but uses a slower four-step process that keeps the rubber where it belongs.
Very happy with the product. Would recommend to others. No problems. I would say this filter was larger than my K&N original filter, which I think is good. Allows more air to reach engine, which may mean more horsepower.

Well, I wasn't looking for more horsepower and didn't expect any so I really haven't noticed any increase over the previous AMSOIL air filter. What I was hoping for was an increase on gas mileage and I'm sorry to say that there was none over two full tanks worth. Even a modest increase would have been nice but I actually am now getting slightly less mileage. For now I am hoping that this new filter will clean the air as well as the AMSOIL filter that they no longer make for my vehicle.

I received my Green replacement air filter in a timely manner. I am pleased with changing to the Green air filter so far in my 2006 Chrysler 300 customer. I have noticed an increase in my MPG and gain in pick up getting on the freeway.

Good looking filter and easy to install, the shipping could have been faster but it came within the promised time. You have to buy a filter cleaner on the manufacturer's website which is around $10-$15, but if the filter can lasts up to the car's life, which is remains to be seen, then I guess it's worth it.

I purchased my Green Performance air filter here simply because it was the cheapest price I found online. I had no problems with my order and I would order from here again.

It seems to work fine. Definitely able to hear engine breather a little more. It's a subtle sound difference, but it's there. Not sure if it's just the car, but there seems to be some type of stall or lag at about 3rd gear when attempting to go WOT. Didn't seem to have this with the stock filter. My mpg has however increased.

Definitely noticed a difference from the paper filter I previously used. Acceleration was quicker, and the car improved with a lower idle rpm and gas mileage. I would recommend this to anyone looking to upgrade an air filter. Easy installation and maintenance for people who like to take care of their car.
