Hi,
H I almost ordered a Siemens hood. But with the common hoods, the charcoal filter has to be replaced about once a year, which costs around 100 €.
With Siemens hoods, there are two options. Either the filters are inside the hood itself, which apparently have to be replaced quite often, or you use the Clean Air module.
The charcoal filter there costs about 65 € and is said to last longer…
The grease is filtered by a metal filter, which you can simply clean in the dishwasher.
However, the problem of having to buy replacement filters will exist with every hood…
Best regards,
Andreas
