Tests show that ducting out is around 35% more efficient than the best available charcoal filters. Therefore, it will always be better to extract cooking odour and humidity outside, rather than opting for recirculating. When ducting is not an option, it's important to find a hood with an efficient charcoal filter. Without good filtration, the hood merely acts as a fan pushing dirty air around in the kitchen. A number of our charcoal filters offer more than 90% recirculation efficiency, however, the cheaper models are often very ineffective, with around 30% filtration. In order to provide the best possible conditions for charcoal filter technology, it is important to follow the grease filter’s maintenance instructions. Regular maintenance of the grease filter helps to ensure the optimal effect of your charcoal filter. Our best charcoal filters have a working lifetime of 900 hours. We recommend using an original charcoal filter intended for the extractor for the best effect. Until other regenerable filters are better documented and tested, we do not recommend them for our kitchen hoods. If you have an older RørosHetta hood and can’t find a replacement charcoal filter for it in the list below, please contact our Customer Service Centre.
