FILTER MAINTENANCE

• How often should I clean my filter?
We recommend that you visually inspect your Green High Performance Air Filter at every oil change. As a general rule, a Green High Performance Air Filter should be cleaned at every 30,000 miles; however, this interval can be greatly influenced by your environment and driving conditions. In dusty areas, you may need to clean the filter more often.


• Can I use an air hose to clean my Green High Performance Air Filter?
We do not recommended using compressed air to clean a Green High Performance Air Filter because of the risk of damage to the filter. We recommend using a soft-bristle brush to remove packed dirt and debris from the filter.


• Can I use other cleaners/oils on my Green High Performance Air Filter?
Only Green Filter USA's biodegradable cleaner and lightweight synthetic oil are approved for use on a Green High Performance Air Filter. Use of other cleaners or oils is not recommended and may void the filter's Limited Lifetime Warranty.


• What makes Green Filter oil different from other brands?

  • Green High Performance Air Filters come pretreated with a specially formulated dirt-trapping oil. Our proprietary lightweight, synthetic Green Filter oil is designed to not damage any vehicle sensors.
  • 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.
  • Green Filter oil also contains a swelling additive for the cotton filtration media. This causes the cotton fibers to swell, which allows the filtration media to collect the very small dirt particles (down to 5 microns) that could otherwise harm your engine.
