Flushing and blowing air through a filter mesh will remove most of the particular debris but not all and after each cleaning there will be more particular matter not completely removed. Which is fine as long as you run a differential pressure guage across the filter element and do filter cleaning based on the pressure differential and not on miles driven or passes made.

These filters catch much smaller particles than spin on throw away filters.
And the flow rate/ lack of pressure drop is incredible. Much, much higher flow rate.
They are FFA approved, lives depend on them.
