Don't have to carry 30 count box around like TarBar or the other filters
Very effective. I use to buy TarBar for a long time. With TarBar, the collected tar oozes down the mouth piece when they get warm, (especially down here in Florida), cutting their re-usage times down.. The Nicfree don't seem to have this problem as much. The convenient, smaller 10 pack boxes are a plus as well. Don't have to carry 30 count box around like TarBar or the other filters.
