Can i use a dust collector to help dust my log cabin?

A dust collector usually won’t solve this — most cabin dust comes from dry, unfinished logs shedding fibers, not from the air system. The best fix is gently cleaning the walls with a soft brush or vacuum and then sealing the interior logs with a finish like oil, wax, or shellac to lock the dust down. Once the logs are sealed, the dust problem usually drops dramatically. Air purifiers can help, but sealing the logs is what really makes the difference.
