The filter is sufficient (according to Siemens customer service) entirely for domestic use from. The more expensive convection sets differ on the filter thickness and are intended for professional use.
After so there is no alternative to the recirculation mode, can I product. If someone has an idea on how the pipes can be reduced please post!
