The only "community" I know about that likes these is the sand rail, and they
ALWAYS use the oiled bag that fits over the cone filter. Without that, they are
NOT effective. They actually filter better when they are dirty, but then
you've lost effective air flow, which is usually why those kinds (oiled filters-
more porous fibers) of filters are used.
