How Often Should I Change My BORA Filter?
The recirculation version of all BORA products rely on the efficient operation of activated charcoal filters and ensure that unpleasant cooking odours do not enter the room air, thus keeping the air in your kitchen always fresh.
Activated charcoal filters absorb unpleasant cooking odours, but their absorption capacity is limited. When activated charcoal is saturated, no further odours can be filtered, which is why the filter has to be replaced at certain intervals.
So how often do you need to replace the activated charcoal filter of your BORA system? It depends on your BORA product and its activated charcoal filter:
BORA Professional & BORA Classic
BORA Pure (PURU) & BORA X-Pure (PUXU)
BORA Basic Models (BFIU, BIU, BHU & GP4U)
HOW WILL I KNOW WHEN IT’S TIME TO CHANGE THE FILTER?
HOW DOES ACTIVATED CHARCOAL ACTUALLY WORK?
Activated Charcoal Filter
Activated charcoal consists mainly of carbon and graphite crystals with a large inner surface and a highly porous structure. Activated charcoal is used both for cleaning liquids and for odours. In the case of our BORA activated charcoal filter, the pore structure ensures that the activated charcoal traps cooking odours in its pores like a sponge. In comparison to a sponge, the activated charcoal stores the odour molecules in its pores and basically does not release them anymore.
In a BORA activated charcoal filter, the filters have an additional “acidic” ion exchanger layer which ensures that certain odour particles such as amino acids in fish are destroyed and thereby made odourless.
