The typical dusty grumpy odor (and was not to superimpose by smell sticks) one from during feeding and accommodating hit by the exhaust air flow, is now finally history.
There is a second filter element with a vacuum cleaner (just behind the dust bag sitting), to which I previously here at Amazon unfortunately not yet have found :-( Simple filter pieces, such as those found in the spare bags from Swirl, not let there namely Insert as the original filter does not allow partial replacement, only the entire filter can be removed (with plastic frame).
