My cooker hood (base model of Bauknecht) is on recirculation mode, so I depend on these active carbon filter with strong cooking odors. Nevertheless, I use the deduction when cooking not always but only so about 4 times a week and not constantly. Thus, the activated carbon filter keeps loose 5-6 months. Then the price delivery is here at Amazon unbeatable price, reliable, fast and - important! - The spare part is original and not plagiarized from China or something.
