Please substantiate your claim on this concerning all washable air filters. The one I have is made By Fram and is not a foam or oil impregnated filter like the K&N. Amsoil also made a filter similar to the Farm Washable one.
It is common to wash the Air Filters on big rigs and other types of engine powered equipment. They actually sell special washers and even dryers for that. Of course they target businesses that own fleets.

You're comparing an industrial application to a consumer application? You aren't comparing apples to apples.
The air filters you're referring to aren't "washable" but they clean them by reversing the flow of the air in a spinning cleaner. These filters are also expensive compared to ours and have a much longer serviceable life.
I agree that the premise that all washable consumer air filters offer less filtration for smaller particles.
