BORA activated charcoal filters – cooking odours don’t stand a chance

When is an activated charcoal filter required? 

All BORA cooktop extractor systems are available as either recirculation or exhaust air versions. The best type of system for a kitchen depends on the specific planning situation. Both operating modes extract steam, grease particles and odours with equal efficacy but there is a difference: with the exhaust air version, the air drawn in by the cooktop extractor is expelled outside via a duct system. With the recirculation version, on the other hand, the drawn-in air is filtered and returned to the room.  

Irrespective of the operating mode, all of our cooktop extractor systems come with an integrated stainless steel grease filter. This is located in the system’s cooktop extractor. The stainless steel grease filter filters grease particles that arise while cooking and can be easily cleaned in a dishwasher.  

As the exhaust air version expels the drawn-in air and cooking odours externally, no further filtration is required with this mode. In the recirculation version, on the other hand, a second filtration stage occurs: odour filtration. All BORA cooktop extractor systems in recirculation mode and the BORA X BO use a premium-quality activated charcoal filter to this end. Thanks to the filter’s pore structure, the activated charcoal absorbs cooking odours in its pores like a sponge absorbs water. The odour particles are then stored in the filter’s pores, preventing unpleasant cooking odours from entering the air in the room.  

How long does a BORA activated charcoal filter last?

The BORA activated charcoal filters absorb and store unpleasant odour particles, providing fresh air when cooking. However, the filters’ absorption capacity is limited and once the activated charcoal is saturated no further cooking odours can be filtered. This makes regular replacement necessary.  

How often and after how long the activated charcoal filter in your BORA system needs to be replaced depends on the specific system and the associated activated charcoal filter. We explain which system requires which filter and when this needs to be changed. 

BORA Basic systems 

The BORA Basic systems BHU, BIU and BFIU use the BORA activated charcoal set (BAKFS) for air filtration. Replacement is necessary after 150 operating hours. The letter ‘F’ appears on the fan’s indicator area when a filter change is due.  

BORA Pure systems 

The BORA Pure systems PURU, PUXU and PURSU use the BORA Pure activated charcoal filter (PUAKF) for air filtration. Replacement is necessary after 150 operating hours. The letter ‘F’ appears on the fan’s indicator area when a filter change is due. 

BORA Professional and BORA Classic 

The modular BORA Professional and BORA Classic systems offer two options for air filtration in recirculation mode: the BORA flexible air purification box (ULBF) or the BORA air purification box with three activated charcoal cartridges (ULB3X). The ULBF has to be replaced after 300 operating hours and the ULB3X after 600. 

On the Professional 3.0 system, the letter ‘F’ appears on the fan’s indicator area when a filter change is due. On the Classic 2.0 system, ‘i FILT’ (less than 20 hours of filter life remaining) or ‘E FILT’ (less than 5 hours of filter life remaining) appears on the display when a filter change is due. 

BORA X BO

The BORA X BO uses the X BO odour filter (XBOGF) for air filtration. Replacement is necessary after 150 operating hours. A message on the BORA X BO’s display reminds you when a filter change is due.
