Cleaning your PowerCore®: One of the benefits of using a dry PowerCore® filter is that you don't have to clean it. Depending on driving and environmental conditions; the filter will eventually become weighed down with dirt after ~100,000 miles or 4 years.
Extended the Filter Life: Remove it from the vehicle and tap gentle on a hard surface or lightly vacuum the filter surface.
If you experience a sudden decrease in mileage or engine performance, the filter will need to be replaced.
DO NOT WASH! Washing your PowerCore® filter will cause it to become soggy and collapse and requires immediate replacement.
DO NOT OIL! Oiling your Dry filter will ruin it and requires immediate replacement.
