The Siemens filter is identical to 100% and absolutely compatible with the above-mentioned Bosch BSG 81466 vacuum cleaner.
(On the packaging of the filter are also d. Logos displayed both manufacturers passu).
Bosch recommends in d. Instructions, the filter from time to time "knock out" or "wash out".
However, retained in the filter dirt particles are at first glance hardly visible,
why "tapping" in my opinion, is rather less helpful.
After 4 months, was, for example. It was not until my filter already slightly dark tinted (wahrscheinl. Carbon / soot ..).
Had then the filter placed in a bowl of water to loosen the dirt out.
But it was less removed the discoloration, but rather dozens of other mini dirt particles
(Skin cells !! ...), which were previously not at all recognizable.
Since the filter also only 30 degrees u. Is washable with a little soap, I think,
that investing in a new filter is definitely more hygienic for around 5 euros.
Conclusion:
- Solid motor protection filter
- Convincing filtration performance (.. Therefore, "washout" wg Hygiene u U. less recommended)
- Compatible to Bosch BSG 81466 vacuum cleaner as identical with Bosch Microsan filter 616 268
- Good value for money for an original spare part (ie: to upgrade no incentive to No-Name)
