you gotta use a little bit of common sense when cleaning any air filter.
the idea is to blow the dust off of the filter from the clean side, not to blow holes in the filter. if i were to (accidentally) blow a hole in a filter
, i would install another filter for sure.
when i am driving on a dusty dirt road, i have to clean the genny air filter every day. my genny is located at the rear of my moho on the drivers side (behind the rear wheels) so it is in a bad area for dirt and dust. at $12 a copy, it would be very expensive (and unnecessary) to replace the filter every day.
i use a large panel k&n oiled gauze air filter for my main engine. with the air inlet in the front grill area, it does not get dirty quickly even on dusty dirt roads.
