THE CHOSEN AIR FILTER BY THE WORLD'S BEST

Don't Take Our Word For It

There are thousands of 5 star reviews from extremely happy customers that have experienced the Green Filter difference.

Amazing Perfect Fit!

Item looks great to say the least. The filter was an amazingly perfect fit for my vehicle. I drive a 2012 Ford Focus 2.0l and it changed out with the old stock filter in literally seconds. No having to wiggle it to fit and literally slid on the intake like butter. Tighten down the flat head bolt to hold it on tight and you're good to go! Great product!!

The Filter Sounds Fantastic.

This filter sounds fantastic, fits in the stock airbox iwth the cover on or off, and isn't terribly expensive. I really enjoy hearing the turbo spool and blowoff through the new filter. Others online have said they've experienced marginally better fuel economy but its too early to say for me. If it is true, its another added bonus.

Awesome & Re-usable

Car can breathe! No but it really can now, the old paper filter is terrible. Replaced it with this one on my 2014 Ford Focus st and car even sounds better now. Can actually hear the intake induction sounds etc a lot more. You can also clean and re oil the filter to use it over and over. What a great bargain for a reusable filter.

Green Filter's Technology Makes All The Difference

Woven Cotton

Deep pleats in the double-layered cotton create a 10-15% increase in filtration surface. This increase allows a greater volume of air to move more freely into your engine cylinders while maintaining superior filtration. Our specially designed cotton filter traps particles as small as 5 microns.

Steel Mesh

Steel wire mesh encases the cotton filter, providing strength and dent resistance so you can be sure your Green High Performance Air Filter will work under the toughest conditions.

Proprietary Lubricant

This oil creates a positive (+) magnetic charge, or ionic bond, with the filter's stainless steel mesh. The positive charge attracts the negatively (-) charged dust particles entering the filter, causing them to cling to the steel mesh and allowing the cotton to remain clear for maximum air flow.

Low Pressure Molding

Other filters use a simple pressure-molded injection process to bond the perimeter rubber to the interior components. That method saves manufacturing time, but in the process, a considerable amount of rubber can seep onto the filtering surface. While it may not look like much, that spill-over rubber can restrict as much as 25% of the intended air flow. We use a four-step production process which virtually eliminates rubber seepage and maintains maximum air flow through the filter.

Custom Molds

Our hand-molded, flexible rubber base offers an airtight seal and absorbs vibration. Our filter molds are created from an extensive on-site library of factory air boxes, with each part custom made on CNC machines. We don't reuse elements between filters or make universal molds, which means that when you buy a Green High Performance Air Filter you can be sure it will fit just like the one from the factory, with no modifications necessary.

In House Technology

Long before we were manufacturing a single air filter for your street-legal machine, we produced hundreds for the international motorsports industry. Our production technology is always improving with the most cutting edge processes and equipment. Also being committed to serving you, our product line is ever expanding to cover all of your needs. We stand by our guarantee of providing customers with what we think is the best filtering technology available.

It's not just better airflow

It's not just about immediate gains, but the long term ones as well.

Better
Performance

Dynamometer bench testing on an 1800cc 4-cylinder engine showed that a Green High Performance Air Filter provided a 6.7% increase in horsepower over the same vehicle with a stock paper air filter.

Fuel
Efficiency

In an independent test performed on a 2008 Chevy, a 5.6% increase in fuel mileage was shown over the same vehicle with a stock paper air filter. This is the same test that manufacturers perform to estimate fuel economy on new vehicles.

Made
In The USA

All Green Filters are made by hand in our Uniontown, Pennsylvania facility with materials manufactured in the USA.

Lasts a
Lifetime

Our filters are designed to be cleaned (with our biodegradable cleaner and synthetic oil) and reused. Not only will you notice a difference in your wallet, but you'll be helping the environment as well.
