Find Your Green Filter

Don't Take Our Word For It

Drivers choose Green Filter for better airflow, easy installation, reusable performance, and long-term value. Here is what customers have experienced after upgrading from a standard paper filter.

I installed a Green Filter on my 2008…

I installed a Green Filter on my 2008 Porsche 997 Turbo, and the difference was noticeable immediately. The engine feels more responsive, performance has improved, and the intake sound is even better—exactly what I was hoping for. I have performance filters from competing brands on several of my other cars because they came with aftermarket cold air intake systems. After experiencing the results with Green Filter, I'll be replacing all of them with Green Filters. I highly recommend this product to anyone looking for a simple upgrade that delivers real performance and sound improvements. P.S. As a nice piece of racing heritage, the Ford GT that won the 2016 24 Hours of Le Mans was equipped with Green Filter.

How a Green Filter Works

Race-proven design, double-layer cotton and a precision fit: here is what makes a Green High Performance Air Filter different from a disposable paper filter.

Let It Breathe.

Clean, free-flowing air is as critical to your engine's performance as the octane of your fuel. Reduce the restrictions in your intake system, and you'll increase the output of your engine. Green High Performance Air Filters are engineered to maximize air flow while trapping harmful dirt particles. The result of this race-proven technology is increased horsepower, improved throttle response, better fuel mileage, and greater torque throughout your engine's RPM range.

Precision Production
At Green Filter USA we use an advanced production process that virtually eliminates seepage into the woven cotton filtration surface, which increases air flow by as much as 25% vs. competing products.
Fit Like a Glove
Every filter we manufacture starts with a precision CNC-machined mold, designed, milled and tested in-house to ensure an airtight, factory-quality fit with no modifications necessary.
Pleats of Strength
Deep pleats in the double-layered cotton create a 10–20% increase in filtration surface. This allows a greater volume of air to move freely into your engine cylinders.
Greater Air Flow
In a side-by-side test bench comparison, Green High Performance Air Filters allowed greater air flow than paper filters.

Ionic Charge. Bionic Performance.

Green High Performance Air Filters come pretreated with a specially formulated dirt-trapping oil. This oil creates a positive (+) magnetic charge, or ionic bond, with the filter's coated 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.

The Best Use of Cotton Since the Invention of Blue Jeans.

Because of its unique properties and organic composition, cotton is the ideal material for use in high performance air filters. But beyond the mere use of the material, Green High Performance Air Filters are uniquely designed, engineered, and manufactured to take full advantage of cotton's capabilities. Unlike multi-layer gauze filters that can fray and release fiber particles into your engine, Green uses two layers of tightly interwoven cotton fabric. Cross-weaving one fine and one medium layer produces a fabric that is thinner and stronger than other materials, while maintaining the ability to trap harmful dirt particles as small as 5 microns. The result is better airflow without sacrificing filtration. And because the fabric is so durable, it can be washed and reused over and over.

Drop It In. Fire It Up.

Green High Performance Air Filters come pre-oiled, so they're ready to use right out of the box. Pop open your air filter box, remove your stock filter and drop in a Green High Performance Air Filter. You simply can't perform a simpler, less expensive upgrade that yields as much improvement in engine performance.

Anyone Can Go Green.
Green High Performance Air Filters are available for virtually every domestic and import car, light truck, and SUV. All Green Filter air filters are covered by a limited lifetime guarantee.
Keep It Clean
Be sure to use only the Green Filter cleaner and oil kit. Others will discolor your filter.

Better Mileage. More Power. Cleaner Air.

Test results for Green High Performance Air Filters compared with stock paper air filters.

5.6%Better fuel mileage
Increased air flow to your cylinders results in a more potent air/fuel mixture. In addition to the performance enhancements Green Air Filters offer, you'll also reap the benefits of increased fuel mileage.
6.7%More horsepower
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 stock paper air filter.
Up to 25%More air flow
Our advanced production process virtually eliminates seepage into the woven cotton filtration surface, which increases air flow by as much as 25% vs. competing products.
5 micronsDirt particles trapped
Two layers of tightly interwoven cotton trap harmful dirt particles as small as 5 microns, so you get better airflow without sacrificing filtration.

What Makes Green Filter a Better Performance Air Filter?

Not all air filters are built the same. Green Filter uses advanced materials, precision molding, and race-proven manufacturing methods to create high-performance car air filters that deliver airflow, filtration, and long-term durability.

Double-Layer Woven Cotton Filtration

Green Filter uses double-layered woven cotton with deep pleats to increase filtration surface area. This allows more air to move freely into the engine while still helping trap harmful particles before they reach critical engine components.

Steel Mesh Support

A durable steel mesh surrounds the cotton filter media, adding strength and dent resistance. This helps the filter maintain its shape and performance even under demanding driving conditions.

Proprietary Filter Oil Technology

Green Filter's specially designed filter oil helps attract and hold dust particles while keeping the cotton media clear for airflow. This helps maintain strong filtration and performance between cleanings.

Low-Pressure Molding Process

Some filters use pressure-molding methods that can allow rubber to cover part of the filtering surface. Green Filter uses a careful molding process designed to reduce rubber seepage and preserve airflow through the filter media.

Custom-Molded Fitment

Green Filter does not rely on one-size-fits-all designs. Filters are built for specific applications to help provide a proper seal, factory-style fit, and easy installation without unnecessary modification.

Race-Proven Manufacturing

Green Filter technology was developed through years of performance and motorsports experience. That same focus on airflow, durability, and filtration is built into every filter made for street and performance vehicles.

Better Airflow. Long-Term Value. Lifetime Performance.

The benefits of Green Filter are not just about experiencing immediate gains, but there are long term ones as well.

Improved Airflow

Green Filter's high-flow design helps your engine breathe more freely compared to a restrictive stock paper filter. Better airflow can support stronger throttle response and improved performance.

Reusable and Washable

Instead of throwing away your air filter every few thousand miles, a Green Filter can be cleaned, re-oiled, and reused. This makes it a smart long-term option for drivers who want performance and value.

Made in the USA

Green Filters are made in Uniontown, Pennsylvania, using quality materials and careful manufacturing processes. Every filter is built with attention to fitment, durability, and performance.

Eco-Friendly Alternative

Because Green Filters are washable and reusable, they help reduce the need for disposable paper filter replacements. That means less waste over the life of your vehicle.

Keeping It Green.

Change your air filter according to your manufacturer's recommended maintenance schedule, and you'll dump 20 paper air filters into our nation's landfills in the first 100,000 miles of driving.* But replace that stock filter with a washable, reusable Green High Performance Air Filter, and it'll be the last one you need. Add the benefits of reduced fuel consumption, and not only will you be helping the environment, you'll be putting a lot of Green back into your pocket.

* Based on recommended air filter replacement every 4,000–5,000 miles, or with every oil change.
