vacuum bags appear to be the same as the original Miele FJM bags except they are much thinner: same locking ring and same bag holder. The filters are also much thinner than the original. Hopefully they are just as good and do the job, but they are definitely lower quality than the original bags so I don't think they will have the same filtration speed and performance as the original bags. The original is made in Germany. These bags are made in China and packaged in the USA.
