Green Filter USA: Racing Heritage, Street-Ready Performance

Green Filter USA was founded in 2001 by Mark German, who channeled years of racing experience and parts manufacturing expertise into a single mission: build an air filter that genuinely outperforms the competition. From day one, the brand set its sights on the motorsports world — engineering filters for the demanding environments of rally racing, endurance road racing, and professional circuit competition — before bringing that same technology to everyday street and truck applications.

The brand's racing pedigree is no marketing gimmick. Green Filter has supplied filters to world-renowned racing engineers, top engine builders, and championship-winning teams. A notable milestone came in 2018, when a Ford GT equipped with Green Filter technology took victory at the Rolex 24 Hour race — a real-world testament to the brand's filtration capabilities under extreme conditions.

What Sets Green Filter Apart

At the heart of every Green Filter product is a two-layer woven cotton media encased in stainless steel mesh. Unlike gauze-based competitors, woven cotton holds filter oil more uniformly, resists wear, and maintains consistent filtration efficiency over time. The filter oil itself creates an ionic bond with the stainless steel mesh, attracting negatively charged dust particles and keeping the cotton media clear for maximum airflow.

Manufacturing precision is equally important. Green Filter uses a four-step, hand-molding production process for the flexible rubber base — a method that virtually eliminates the rubber seepage common in pressure-molded competitors, which can restrict up to 25% of intended airflow. Every mold is built from an extensive on-site library of OEM air boxes and machined on CNC equipment, ensuring each air filter fits exactly like the factory original — no trimming, no adapters, no compromises.

Green Filter's performance air filters are engineered to trap particles as small as 5 microns — meeting OEM engine filtration standards — while simultaneously promoting increased airflow for better throttle response, improved fuel efficiency, and greater horsepower. Because the cotton media is washable and re-oilable, a single Green Filter can last the lifetime of the vehicle, making it both an environmentally conscious and economically smart upgrade over disposable paper filters.

Green Filter products are proudly manufactured in the United States, and the brand's ever-expanding catalog covers a broad range of cars, trucks, SUVs, and motorcycles — from daily drivers like the Ford Focus and Chevrolet Silverado to performance icons like the Corvette, Mustang, Subaru WRX, and BMW M-Series. Whether you're a weekend track warrior, a show car enthusiast, or simply a driver who demands more from every component under the hood, Green Filter USA delivers filtration technology that started on the podium and belongs in your engine bay.
