The bags work perfectly with our red Bosch vacuum cleaner. However suit attached motor filter, which should be used behind the bag, not to Bosch. Apparently, here are Siemens and Bosch not identical. The accompanying filters are no Hepa filter, which are installed at the air outlet. Anyway, the Hepa filter when Bosch must never be replaced - according to dealer information.
Unfortunately, I was on my request for use of filters from Bosch still no answer.
Nevertheless, the product is recommended, as it is indeed bought only because of the dust bag. The filters are then halt unnecessary. Priced, it is still far cheaper than the "original" -4er pack.
