always use the Miele as it perform well but never think to look for a alternative . with the increase cost I go to the filtrete by 3M and do not like the stiff plastic inlet fitting . it leak and there be a lot of dust inside the filter compartment . the closure fitting would not close completely when remove and dispose of the bag . more dust . be now use the Envirocare at a very substantial savings and have find they be every bit as good as the Miele . the inlet fitting be not plastic but cardboard but work very well . not a speck of dirt inside the filter compartment . actually , if memory still serve I well the original Miele be cardboard . the envirocare be the only bag that I will buy . top performance and great value .  for MIELE Vacuums f j m -lrb- 25 bag + 10 filter -rrb-
