My Siemens vacuum cleaner so had a Hepa filter already in it, after 2 years but who was already deep black, so I went on the search for a new filter. Everything went well on Amazon as always, and the filter was perfect in my vacuum cleaner VS 06G series. Such a filter should be already at the latest refresh this every 2 years time, or even better every year, but is of course not cheap with nearly 17 Euros.
In any case, the filter is fine and filters the dust even from the air, I think that is a good thing.
