According to Volant and Donaldson (Who actually makes the filter) http://www.donaldson.com/en/engine/s...datalibrary/00 1220.pdf there is no need to clean the filter because of it's design but I do use my compressor to blow it out in reverse to the airflow. The cool thing about this filter is it's water proof so those of us who ford streams and rivers don't have to worry.

If you already have a CAI they do just sell the filters and you can find your size here. Volant PowerCore™ Filters
