Which Air Filter is Better: Foam or Paper?

When it comes to air filters, foam and paper are two of the most popular options. But which one is better?Foam filters are known for their superior filtration capabilities, as they can hold more dirt than any other type of filter. This makes them ideal for dusty conditions, and they can be washed and reused hundreds of times. However, when it comes to street cyclists who travel long distances, an OEM paper filter is the preferred choice.

Paper filters are made up of multiple layers, which makes them more effective at blocking dust particles than foam or cotton gauze filters. As the filter accumulates more dirt, its resistance to air flow increases, resulting in decreased power and fuel economy. On the other hand, wetting an OEM paper or gauze filter causes the fibers to swell and throttle the air flow, potentially stopping the engine. This is because dirt particles adhere to the outside of the filter and become part of the filter medium.

As a result, air must first pass through these particles before entering the engine. K&N air filters provide superior filtration without sacrificing airflow over a longer period of time. This is why most dirt bikes and off-road bikes contain foam air filters instead of paper filters. If you want to wash your foam filter, simply remove it from the filter and then remove the foam. The comment about being able to see light through a filter as bad is quite misleading, since that is precisely the best way to test a paper filter to determine if it is clogged. Most oil foam filters are oiled to better filter dust, dirt, and other air contaminants. In conclusion, both foam and paper air filters have their advantages and disadvantages.

For dusty conditions, foam filters are the best option. However, for street cyclists who travel long distances, an OEM paper filter is the preferred choice.
