Reusable Synthetic Air Filters


Some aftermarket performance air filters are made of synthetic materials and designed to flow more air than a paper filter while providing an oil free solution to washable, reusable filters. Most synthetic air filters use a wire mesh for structural support bound by a rubber mold.

Can a synthetic air filter increase my horsepower?
Synthetic air filters are designed to allow air to flow with little restriction into the engine. These air filters have material that is thicker than paper. It filters air as the air works its way through the material, not just on the filter's top surface. This allows the filter to flow air with less restriction and hold more dirt for long intervals between cleaning. Less restriction usually results in better power and torque.

How do I service a synthetic air filter?
Synthetic air filters, like cotton air filters, are washable and reusable, but do not always require the use of oil. They use a tight weave of synthetic material to achieve the filtration efficiency needed to protect your engine. Always use the manufacturer's recomended cleaning methods to avoid issues with your warranty. AEM Air Filters is a major player in the synthetic air filter world. Their oil-free air filters can be used up to 50,000 miles before cleaning is needed depending on driving conditions. These air filters are cleaned using a sythetic air filter cleaner. Spectre Performance makes a low cost oiled synthetic air filter that looks a lot like a cotton air filter, however, it has a shorter life. Some Spectre air filters can be cleaned several times and are often a great value because of their low initial cost. AIRAID synthetic air filters use a non-oiled dry filter media and can be serviced with the AIRAID Tune-Up Kit.

How often do I need to clean a synthetic air filter?
Most synthetic replacement air filters are designed to withstand numerous cleanings without deteriorating. Depending on your specific driving conditions, you may be able to get up to 50,000 miles before needing to clean a reusable synthetic air filter. The large synthetic air filters used on AEM Cold Air Intakes can be used for as much as 100,000 miles depending on driving conditions.

Are synthetic air filters environmentely friendly?
This is not a throw away air filter that takes up space in landfills with wasted air filter material. Millions of automotive air filters are thrown away every year. Reusable products, like synthetic air filters, are a great way to be environmentally friendly.

What about a warranty for synthetic air filters?
Many synthetic air filter manufacturers offer a lifetime limited warranty for their OE stock replacement air filters for street cars and trucks. These companies stand behind their product which builds confidence with the consumer that their synthetic air filter will be that last one they will ever need to buy for their vehicle.

Why buy a synthetic air filter?
Most synthetic air filters are reusable and have a lifetime limited warranty which means you buy one filter and don't buy another one for your car ever again. While reusable synthetic air filters might not have the least restriction of all air filters they typically restrict air less than paper so often you will see a performance gain. Good for the environment, easy to clean and they can help your car run better, what more do you need?
