What replace charcoal filter
actually means.
When a Bosch wall hood returns air to the kitchen instead of ducting it outside, an activated carbon filter holds the odors. The display counts 120 hours for it, four times the grease filter interval, and then asks for a new one. The count only matters once the display has been switched to circulating-air mode.

The hood has counted enough hours of fan time to ask for its filters: the mesh or baffle grease filters want a wash, or on a recirculating hood the charcoal filters want replacing. Most hoods count hours rather than measure grease, so the light comes on whether the filters are clean or not, and it stays on until it is reset with the key the manual names. A reminder that returns straight after a reset, or a hood that still pulls weakly with fresh filters, is worth a visit.

What not to do
Replace charcoal filter is not the grease filter message, and washing the carbon filter does not bring it back. On a hood ducted outdoors the message should not appear at all once the display is set to exhaust mode.
