In EcoSwitch mode, the berbel hybrid filter ensures that the air is cleaned and then returned to the room in recirculation mode. Just like the berbel recirculation filter, the active carbon in a hybrid filter must be changed every 2-3 years. This is really easy to do with a cost-effective refill pack. However, the hybrid filter has even more to offer: Whether to improve performance in recirculation mode or as an overpressure valve for exhaust air mode, the berbel hybrid filter can be used completely flexibly.
